Abstract

Species of the subgenus Tatsipolia Benedek, Behounek, Floriani & Saldaitis, 2011 of
the genus Dasypolia Guenée, 1852 are reviewed and the genus-group names Chalapo-
lia Benedek, Behounek, Floriani & Saldaitis, 2011 and Kitapolia Benedek, Behounek,
Floriani & Saldaitis, 2011 previously considered as distinct subgenera of Dasypolia
are synonymised with Tatsipolia. Six new species are described from southern Xi-
zang, China: Dasypolia (Tatsipolia) polymorpha sp. nov., Dasypolia (Tatsipolia) inter-
media sp. nov., Dasypolia (Tatsipolia) amoena sp. nov., Dasypolia (Tatsipolia) diffusa
sp. nov., Dasypolia (Tatsipolia) luxuriosa sp. nov., and Dasypolia (Tatsipolia) ultra-
montana sp. nov. Adults and male and female genitalia of all species in Dasypolia
(Tatsipolia) are illustrated.

Key words: Antitypina, new synonym, Noctuinae, owlet moth, Xylenini

Introduction

Dasypolia Guenée, 1852 is a large owlet moth genus distributed in Palearc-
tic Region and reaching its greatest diversity in high mountain areas of Asia.
The genus belongs to the subtribe Antitypina of the tribe Xylenini of the sub-
family Noctuinae (Lafontaine and Schmidt 2010; Zahiri et al. 2011; Keegan et
al. 2021). Many species of Dasypolia were described during the last two de-
cades (Nupponen and Fibiger 2006; Ronkay et al. 2010, 2014, 2023; Bened-
ek et al. 2011, 2014; Volynkin 2012; Benedek and Saldaitis 2014; Chen et al.
2022; Pekarsky and Pekarska 2022). However, the fauna and taxonomy of the

249

Enyong Chen et al.: On the taxonomy of the subgenera Tatsipolia, Chalapolia, and Kitapolia of the genus Dasypolia Guenée

genus sensu lato are understudied in the highest mountain regions of eastern
Himalaya and southern part of the Tibetan Plateau and it is likely that additional
undescribed species will be found.

The genus is currently subdivided into nine subgenera (Benedek et al. 2011,
2016; Benedek and Saldaitis 2014; Ronkay et al. 2014; Gordeev et al. 2023;
Ronkay and Ronkay 2023), some of which are substantially different from the
nominate one in their genitalia morphology. The subgenus Tatsipolia Benedek,
Behounek, Floriani & Saldaitis, 2011 was erected to solely include Dasypolia
(Tatsipolia) ruficilia Benedek, Behounek, Floriani & Saldaitis, 2011 (Benedek
et al. 2011). Subsequently, another species of the genus, Dasypolia vignai L.
Ronkay & Zilli, 1993 was assigned to Tatsipolia after the discovery of the male
of the species (Benedek and Saldaitis 2014), and eight years later, the subge-
nus was reviewed by Chen et al. (2022), who described two additional species
from southern Xizang Province of China. Two other subgenera morphologically
similar to Tatsipolia, Chalapolia Benedek, Behounek, Floriani & Saldaitis, 2011
and Kitapolia Benedek, Behounek, Floriani & Saldaitis, 2011 were erected to
solely include Dasypolia (Chalapolia) brandstetteri Benedek, Behounek, Floriani
& Saldaitis, 2011 and Dasypolia (Kitapolia) kita Benedek, Behounek, Floriani &
Saldaitis, 2011, respectively (Benedek et al. 2011), and both remained mono-
typic up to date.

During further entomological studies in the southern Xizang, extensive ad-
ditional materials on Dasypolia sensu lato comprising six unidentified spe-
cies were collected by the senior author of the present paper. After com-
paring the male genitalia structures of those species with other species in
the genus, they proved to belong to the subgenera Tatsipolia and Chalapolia
and express significant distinctive characters from known taxa and therefore
represent species new to science. Additionally, the detailed examination of
their morphology led to the conclusion that the type species of Tatsipolia,
Chalapolia and Kitapolia display no fundamental differences in their genitalia
of both sexes and are nothing more than species groups within the same sub-
genus. In the present paper, Tatsipolia is selected as the senior genus-group
name for this complex with Chalapolia and Kitapolia being synonymised with
it, all species included into the subgenus Tatsipolia are reviewed and six new
species are described.

Diagnosis. Species of D. (Tatsipolia) are relatively small owlet moths externally
reminiscent of members of the genus Cteipolia Staudinger, 1896 (see Gordeeva
et al. 2023; Volynkin et al. 2024), from which D. (Tatsipolia) differs clearly in the
genitalia morphology of both sexes. The male genital capsule ground plan of
D. (Tatsipolia) is similar to Dasypolia s. str. (e.g., see Ronkay et al. 2001, 2014)
and the main differences are found in the phallus and vesica: in D. (Tatsipolia),
the phallus carina is smooth and the vesica bears one or two clusters of spine-
like cornuti medially whereas the carina of Dasypolia s. str. bears a dentate plate
and the vesica is unarmed. In the female genitalia, D. (Tatsipolia) has asymmet-
rical anterior sclerotisations of the ductus bursae (it is evenly sclerotised in the
similar genus) and a reduced appendix bursae, which is well-developed and
semiglobular or conical in Dasypolia s. str.

Taxonomic accounts

The D. (T.) vignai species group

Diagnosis. The male genitalia of the species group are characterised by the
reduced harpe, which may be present as a short tubercle. In the female genita-
lia, the ostium bursae is broad, the ductus bursae has three regions of sclero-
tisation (the posterior of which forms a ventral margin of the ostium bursae),
and the anterior (dilated) section of the corpus bursae is short (equal to the
ovipositor length or shorter).

Diagnosis. The species largely varies in its forewing colouration (from mouse
grey to ochreous with slate grey suffusion) and the degree of the forewing pat-
tern development within the same population. Dasypolia polyformis sp. nov. is
most morphologically similar to D. cerritula, from which the new species differs
in the somewhat larger size, the broader forewing, and the paler ground colour
and cilia of both wings. In the male genital capsule, D. polyformis sp. nov. is
distinguished from D. cerritula by the broader uncus, the somewhat narrower
cucullus with thinner setae, the somewhat longer ampulla extending beyond
the ventral margin of the valva, and the somewhat broader but shorter juxta
with a narrower medio-dorsal process. As the female of D. cerritula is unknown,
the female genitalia of D. polyformis sp. nov. were compared with D. sejilaensis
and D. vignai, from which the new species differs in the narrower ostium bur-
sae, the shorter anterior sclerotised plate of the ductus bursae, and the corpus
bursae less curved sideways.

Description. External morphology of adults (Figs 1-9). Forewing length
12.0-13.0 mm in males and 13.0-14.0 mm in females. Antenna serrulate
in male and filiform in female. Body covered with long hair-like scales, dark
brownish-grey with admixture of pale grey. Forewing elongate, with anteme-
dially convex anal margin and evenly convex outer margin. Forewing ground
colour varying from mouse grey to ochreous with grey suffusion. Forewing
pattern diffuse, blackish-brown, sometimes indistinct. Subbasal line short,
indistinct. Subbasal longitudinal dash narrow, diffuse. Antemedial line irreg-
ularly sinuous. Orbicular marking elliptical, pale with blackish-brown margin.
Reniform marking narrow, semilunar, pale with indistinct dark margins. Post-
medial line antero-medially curved outwards, dentate on veins. Subterminal
line interrupted into row of blackish irregular spots of various sizes. Terminal
line black, interrupted into spots between veins. Forewing cilia long, grey-
ish-brown. Hindwing pale grey, suffused with brownish grey, with thin grey-
ish-brown marginal line and large and diffuse, semilunar grey discal spot.
Hindwing cilia long, pale brownish-grey. Male genitalia (Figs 39-41). Teg-
umen short, penicular lobe large, trapezoid with elongate posterior corner.
Vinculum somewhat longer than tegumen, robust, U-shaped. Valva lobular
with well-sclerotised costa and oblique editum bearing digitiform and api-
cally pointed distal ampulla directed distally-ventrally and protruding beyond
the ventral margin of valvula and exceeding ventral corner of cucullus. Cucul-
lus trapezoidal with rounded corners, densely covered with spine-like setae.
Sacculus broad (~2/3 of valva width proximally). Clasper oblique, slightly
curved and dilated distally, without harpe. Valvula shortly triangular, slightly
protruding ventrally. Juxta heavily sclerotised, broad, rectangular with round-
ed corners, with short, triangular, and apically pointed dorso-medial process.

Phallus broad with rounded coecum, distally dilated. Proximal section of
vesica granulose, as broad as distal end of phallus, distally tapered and ex-
tended into membranous vesica ejaculatorius directed distally, with short
semiglobular dorsal subbasal diverticulum, and two unequally elongate lon-
gitudinal clusters of spike-like cornuti on its sides. Female genitalia (Figs 59,
60). Ovipositor short, broad, conical. Papilla analis elongate trapezoidal with
rounded corners, weakly sclerotised and setose. Apophyses elongate and
narrow, rod-like, heavily sclerotised, slightly tapered distally, anterior one
shorter than posterior one (~70% of its length). Ostium bursae broad, its ven-
tral margin with heavily sclerotised, belt-like antevaginal plate. Ductus bursae
asymmetrical with somewhat longer right side and asymmetrical, sclerotised
plates dilated to the right side: short and belt-like medial one, and broad and
almost triangular anterior one. Posterior section of corpus bursae more or
less tubular, somewhat dilated posteriorly. Anterior section of corpus bursae
broad, teardrop-shaped, its ventral wall medio-posteriorly with small signum
with irregular margins varying in size and degree of sclerotisation. Appendix
bursae vestigial, conical, situated postero-laterally on right side at corner of
anterior sclerotised plate of ductus bursae.

Etymology. The specific epithet is an adjective derived from the Greek
mtoAupopuno (polyphormis) meaning polymorphic and refers to the fact that
the new species has several colour forms.

Distribution. The new species is currently known from three localities in
southern Xizang, China.

[Altitude] 4500 m (coll. [leg.:] Pan Zhaohui | and Chen Enyong)” (TAAHU).
Diagnosis. The forewing length is 11.5 mm in the male holotype. Dasypolia
cerritula is most morphologically similar to D. polyformis sp. nov. and a detailed
comparison is provided above in the diagnosis of the latter. Another similar
species is the sympatric D. sejilaensis, from which D. cerritula can be distin-
guished by the greyish-brown hindwing with a smaller and rounded discal spot
whereas the hindwing of D. sejilaensis is creamy with intense greyish suffu-
sion outwardly and along the costal and anal margins, and its discal spot is
large and falcate. The abdomen of D. cerritula is covered with black hair-like
scales medially and distally whereas it is unicolourous brown in D. sejilaensis.
In the male genital capsule, D. cerritula differs from D. sejilaensis in the narrow-
er uncus, the larger penicular lobe with a more elongated posterior corner, and
the shorter valva with a markedly broader cucullus densely covered with more

robust setae. Additionally, the ampulla of D. cerritula is shorter and thinner than
in D. sejilaensis, the valvula is markedly shorter and not protruding ventrally, the
harpe is absent (it is present and tubercle-like in D. sejilaensis), and the juxta is
narrower and bears a somewhat shorter and basally broader posterior medial
process. The phalli and the vesica configurations of the two species are very
similar but D. cerritula has two clusters of cornuti (vs 1 in D. sejilaensis).

Distribution. The species is currently known only from its type locality in
southern Xizang province of China.

Diagnosis. The forewing length is 11.0-12.0 mm in males and 13.0 mm in
the female. Dasypolia sejilaensis is externally reminiscent of D. vignai but is
distinguished by its forewing shape, which has a straight costal margin and a
more elongate apex, and the more diffuse forewing pattern in males, and the
longer hindwing discal spot in both sexes. Additionally, compared to D. vignai,
the reniform stigma of D. sejilaensis is situated closer to the forewing costa,
and the pale suffusion on the transverse lines and stigmata is grey whereas it
is brown in the congener. The male genital capsule of D. sejilaensis differs from
D. vignai in the broader valva with a broader and less downcurved cucullus, the
shorter but markedly thicker and upcurved ampulla (it is downcurved in D. vig-
nai), the broader sacculus, and the less prominent and triangular valvula, which
is more rounded in D. vignai. Additionally, the uncus, penicular lobe and juxta
of D. sejilaensis are broader than in D. vignai. The phallus of D. sejilaensis is
shorter and broader than in D. vignai (in proportion to the genital capsule). The
vesicae of the two species are similar but the cornuti are more or less equal in
size in D. sejilaensis whereas the distal cornuti of D. vignai are markedly longer
and thicker than the proximal ones. In the female genitalia, D. sejilaensis can be
distinguished from D. vignai in the longer apophysis anterior (in proportion to
the ovipositor length), the narrower, more asymmetrically sclerotised and side-
ways curved ductus bursae (it is nearly straight in D. vignai), and the straight
posterior section of the corpus bursae, which is sideways curved in D. vignai. A
detailed comparison with another similar species, the sympatric D. cerritula is
provided above in the diagnosis of the latter.

Distribution. The species is currently known only from its type locality in
southern Xizang province of China.

07.x.2011,29°53.097’N, 102°00.459’E, A. Florianileg., gen. slide no.: JB2170 (AFM).

Diagnosis. The forewing length is 12.0 mm in both sexes. Dasypolia vignai is
externally similar to D. sejilaensis and D. cerritula but distinguished by the fore-
wing having a slightly convex costal margin and a shorter and more rounded
apex, and the more distinct forewing pattern in males, and the shorter hindwing
discal spot in both sexes. Additionally, compared to the similar congeners, in
D. vignai the reniform stigma is situated more inwardly from the forewing costa.
The male genitalia of D. vignai differ clearly from other species in the D. vignai
species group in the narrow cucullus, the long, downcurved and apically point-
ed ampulla, and the large and rounded valvula. A detailed comparison with the
most morphologically similar D. sejilaensis is provided above in the diagnosis
of the latter.

Distribution. The species is known from two localities in Sichuan Province,
south-western China.

prep. No.: BG7015 (prepared by Behounek) (ZSM).

Diagnosis. The forewing length is 12.0 mm in the male holotype. Dasypolia
ruficilia differs externally from other species in the D. vignai species group in
the unicolourous pale brown forewing ground colour and the reddish-brown
forewing cilia, and is most reminiscent of D. brandstetteri, from which, however,
it can be easily distinguished by the markedly shorter rami of the male antenna
and the lack of the longitudinal black stripes in the cell and along the vein A1,
which are characteristic of D. brandstetteri. Additionally, unlike in D. brandstet-
teri, D. ruficilia has a forewing with a more medially convex costal margin and a

less elongate apex, reddish-brown cilia, and distinct transverse lines. The male
genitalia structure of D. ruficilia is similar to D. intermedia sp. nov. and a detailed
comparison is provided below in the diagnosis of the latter.

The female is unknown.

Distribution. The species is known only from its type locality in western Sich-
uan Province of China (Benedek et al. 2011).

Diagnosis. Dasypolia intermedia sp. nov., with its larger size, elongate fore-
wing and bipectinate male antenna, is externally readily different from other
species in the D. vignai species group and is reminiscent of certain members of
the D. nivalis species group, namely D. diffusa sp. nov., from which D. intermedia
sp. nov. is distinguished by the more elongate forewing with a darker ground
colour and more distinct markings. The male genital capsule of the new spe-
cies is most reminiscent of the externally dissimilar D. ruficilia but differs in the
narrower uncus, the longer and broader valva, the shorter cucullus with a nar-
rower setose area, the thicker ampulla directed more distally, and the broader
clasper with a slightly larger harpe directed anteriorly (inwards). Additionally,
unlike D. ruficilia, the juxta of D. diffusa sp. nov. is more weakly sclerotised,
anteriorly narrower, and bears a shorter and triangular medio-dorsal process,
which is thumb-shaped in D. ruficilia. The phallus of D. diffusa sp. nov. is distally
narrower than in D. ruficilia, and the vesica has a considerably longer proximal
section and bears only one cluster of larger cornuti whereas there are two clus-
ters in D. ruficilia. As the female of D. ruficilia is unknown, the female genitalia of
D. diffusa sp. nov. were compared with other species of Tatsipolia s. str., from
which the new species differs clearly in the markedly longer posterior sclero-
tised region of the ductus bursae forming a glass-shaped antrum (whereas in
other species of the D. vignai species group, it is short and belt-like), and the
gelatinous and globular anterior section of the corpus bursae bearing a sclero-
tised plate, which is similar to that of certain species of the D. nivalis species
group, whereas in other species in the D. vignai species group, the anterior sec-
tion of the corpus bursae bears a larger and flattened sclerotised plate. Addi-
tionally, the anterior section of the corpus bursae of the new species lacks the
signum, which is present in other members of the D. vignai species group but
also absent in the D. nivalis species group.

medial sclerotisation while anterior part dilated, globular, gelatinous with scle-
rotised plate anterio-laterally. Corpus bursae egg-shaped, membranous, short-
er than ductus bursae. Appendix bursae vestigial.

Etymology. The specific epithet is a Latin adjective meaning intermediate
and refers to the external and genital morphology of the new species, which
appears as intermediate between the D. vignai and D. nivalis species groups.

Distribution. The new species is currently known from its type locality in
southern Xizang, China.

Diagnosis. The male genitalia of the D. nivalis species group differ from the
D. vignai species group in the well-developed, clavate harpe. In the female gen-
italia, compared to the D. vignai species group, the ostium bursae is consider-
ably narrower, the ductus bursae has two regions of sclerotisation with a mem-
branous ventral margin of the ostium bursae, and the anterior section of the
corpus bursae is longer than the ovipositor.

holotype (AFM, ASV, BBT).

Diagnosis. The forewing length is 12.0 mm in males. Dasypolia brandstetteri
with its strongly bipectinate male antenna, brown colouration, and the lack of
the forewing transverse lines, is externally dissimilar to other species in the D.
nivalis species group and is most reminiscent of D. ruficilia, a detailed compari-
son with which is provided above in the diagnosis of the latter. The male genital
capsule of D. brandstetteri is distinct from other species in the D. nivalis species
group by the narrower cucullus and the triangular valvula protruding ventrally.
The vesica structure of D. brandstetteri is most reminiscent of D. nivalis with its
vesica having a ventral diverticulum but in the former species the diverticulum
is longer and bilobate.

The female is unknown.

Distribution. The species is currently known only from its type locality in
western Sichuan Province, China.

Enyong Chen et al.: On the taxonomy of the subgenera Tatsipolia, Chalapolia, and Kitapolia of the genus Dasypolia Guenée

Diagnosis. Dasypolia amoena sp. nov. is externally vaguely reminiscent of
D. nivalis but can be readily distinguished by the serrulate male antenna (it is
shortly bipectinate in D. nivalis), the somewhat broader forewing with slightly
more convex costal and anal margins, the bluish-grey forewing ground colour
(vs brown or grey brown in D. nivalis), the orange suffusion on the claviform,
orbicular and reniform markings and the subterminal line, and the lack of the
intense grey suffusion along the hindwing costal and outer margins, which is
characteristic of D. nivalis. Additionally, the head and the thorax of the new
species are pale grey with admixture of dark grey and ochreous hair-like scales
whereas in D. nivalis they are more unicolourous dark brown. The male genital
capsule of D. amoena sp. nov. is similar to D. diffusa sp. nov., D. luxuriosa sp.
nov., D. ultramontana sp. nov. and D. nivalis but differs in the broader cucullus
and the apically narrower harpe. The phallus of D. amoena sp. nov. is shorter
and broader than in the similar species. The vesica configuration of D. amoena
sp. nov. is most similar to D. u/ltramontana sp. nov. with its semiglobular ventral
diverticulum but differs in the markedly smaller cornuti gathered into two more
elongate clusters, which are more distant from each other than in the congener.
Among species of the D. nivalis species group with known females, the female
genitalia of D. luxuriosa sp. nov. are most similar to D. amoena sp. nov., but in
the latter the medial, membranous section of the ductus bursae is longer, the
sclerotised plates of the anterior gelatinous region of the ductus bursae are
larger, and the corpus bursae is considerably shorter.

Description. External morphology of adults (Figs 22-24). Forewing length
11.0 mm in male holotype and 14.0 mm in females. Female larger than male
and with more elongate forewing, paler ground colour and more distinct and
contrast pattern, and more intense orange suffusion on certain markings. An-
tenna shortly serrulate in male and filiform in female. Body pale grey with ad-
mixture of blackish scales. Forewing elongate with oblique tornus. Forewing
ground colour grey with blackish suffusion. Pattern elements dark grey. Subbas-
al and antemedial lines irregularly sinuous. Costa with irregular blackish spots.
Claviform dash elongate and protruding into medial area, suffused with orange.
Orbicular marking small, elliptical with diffuse blackish margins, filled with pale
grey in male and suffused with orange in female. Reniform marking pale grey
with diffuse blackish margins and black dot-like core spot, in female intense-
ly suffused with orange proximally and distally. Postmedial line thin, question
mark-like curved, dentate on veins, suffused with pale grey along outer margin.
Subterminal line irregular and diffuse, in female suffused with orange. Terminal
line black, interrupted on veins. Forewing cilia pale grey with admixture of dark
grey. Hindwing pale grey with dark grey suffusion, darker in male. Terminal line
dark brownish-grey, thin. Discal spot elliptical and diffuse, broader in female.
Hindwing cilia pale ochreous. Male genitalia (Fig. 50). Uncus elongate, distally
tapered, and apically pointed. Tegumen with short and swollen, rounded penic-
ular lobes. Vinculum as long as tegumen, heavily sclerotised, U-shaped. Valva
lobular, somewhat shorter than annulus, with almost parallel margins. Costa
narrow, distally dilated and reaching cucullus. Cucullus lobular, rounded, densely
covered with robust setae. Editum thin and weakly sclerotised, stretching along
costa and fused with it dorsally, bearing short triangular and apically rounded,
ventrally directed distal ampulla originating at the ventral corner of cucullus
and not protruding beyond the ventral margin of valvula. Valvula short and not

protruding ventrally. Sacculus trapezoidal, broad (~3/4 of valva width). Clasper
oblique, straight, apically dilated, with elongate clavate harpe well-protruding be-
yond dorsal margin of valva. Juxta trapezoidal, with short, triangular medio-dor-
sal process. Phallus broad with rounded coecum, somewhat dilated distally.
Proximal section of vesica short and somewhat broader than phallus, with very
short but broad, protrusion-like ventral diverticulum and two short longitudinal
clusters of small spine-like cornuti dorsally and ventrally. Vesica ejaculatorius
tubular and membranous, originating apically and directed distally. Female gen-
italia (Fig. 64). Ovipositor short, conical. Papilla analis elliptical, setose. Apoph-
yses elongate and thin, proximally flattened and distally rod-like, more or less
equal in length. Ostium bursae moderately broad, with membranous margins.
Ductus bursae elongate, somewhat constricted medially and globular and gelat-
inous anteriorly. Medial sclerotised plate situated posteriorly, elliptical. Anterior
gelatinous section of ductus bursae with two medio-lateral sclerotised plates of
different sizes. Corpus bursae membranous, elongate pear-shaped. Appendix
bursae vestigial, conical, situated ventrally at junction with ductus bursae.

Etymology. The specific epithet is a Latin adjective meaning pleasant and
refers to the beautiful external appearance of the new species.

Distribution. The new species is currently known from two localities in
southern Xizang, China.

Diagnosis. Dasypolia diffusa sp. nov. is externally clearly different from other
species in the D. nivalis species group by its ash-grey forewing ground colour and
the indistinct forewing markings. The male genital capsule structure of D. diffu-
Sa sp. nov. is most similar to D. /uxuriosa sp. nov. but in the former the uncus is
broader, the harpe is apically narrower, and the valvula is more protruding ventral-
ly than in D. luxuriosa sp. nov. Compared to D. /uxuriosa sp. nov., the vesica of D.
diffusa sp. nov. has a markedly narrower proximal section and bears two elongate
row-like longitudinal clusters of smaller cornuti whereas in D. /uxuriosa sp. nov.
the cornuti are gathered into short, bunch-like clusters. In the female genitalia, D.
diffusa sp. nov. differs clearly from other species in the D. nivalis species group in

Diagnosis. Dasypolia luxuriosa sp. nov. is externally vaguely reminiscent of
D. ultramontana sp. nov. but differs in the shorter rami of the male antenna, the
larger size, the broader forewing, the darker grey forewing ground colour, the
less sinuous antemedial line, and the narrower, falcate reniform marking lack-
ing the dark core spot. Additionally, unlike in D. ultramontana sp. nov., the inner
triangular dashes of the subterminal line of D. Juxuriosa sp. nov. are more dis-
tinct and longer, and the hindwing is suffused with brownish-grey medially and
along the anal margin whereas in D. ultramontana sp. nov. it is paler but with
intense grey suffusion along the costal and outer margins. The male genitalia
of the two species are similar but in D. /uxuriosa sp. nov. the uncus is somewhat
longer, the juxta is broader, the sacculus is narrower, and the vesica lacks the
ventral diverticulum. As the female of D. ultramontana sp. nov. is unknown, the
female genitalia of D. luxuriosa sp. nov. were compared with D. amoena sp.
nov., a detailed comparison with which is provided above in the diagnosis of
the latter species.

Description. External morphology of adults (Figs 29-34). Forewing length
14.0-15.0 mm in males and 14.0 mm in females. Antenna shortly bipectinate
in male and filiform in female. Head and thorax dark grey with admixture of pale
grey. Forewing triangular with rounded apex and convex anal margin. Forewing
ground colour grey with slight dark grey suffusion. Pattern elements blackish.
Subbasal and antemedial lines irregularly sinuous, antemedial one edged with
pale ochreous grey inwardly. Costa with series of irregular blackish spots. Or-
bicular marking elliptical, small, with blackish margins, filled with pale grey or
off-white. Reniform marking semilunar, with blackish margins, filled with off-
white. Postmedial line question mark-like curved, irregularly dentate on veins,
edged with pale ochreous grey outwardly. Subterminal line irregular, interrupted
into series of triangular dashes of different sizes. Terminal line thin, interrupt-
ed on veins. Cilia dark grey with admixture of pale grey scales. Hindwing pale
ochreous grey with slight dark grey suffusion along costal and outer margins.
Discal spot semilunar, diffuse. Terminal line thin, ochreous grey. Hindwing cil-
ia grey. Male genitalia (Figs 53, 54). Uncus swollen, elongate, distally tapered
and apically pointed. Tegumen with rounded and swollen penicular lobes. Vin-
culum somewhat longer than tegumen, heavily sclerotised, U-shaped. Valva
lobular, slightly tapered distally. Costa distally dilated and reaching cucullus.
Cucullus rounded and densely covered with setae. Editum thin, stretching along
ventral margin of costa and dorsally fused with it, bearing narrow triangular
distal ampulla directed ventrally and not protruding the ventral margin of valva.
Sacculus trapezoidal, ~1/2 of valva width. Clasper oblique, ventrally straight
and dorsally dilated and upcurved, bearing clavate harpe protruding beyond

Diagnosis. Dasypolia ultramontana sp. nov. is morphologically similar to
D. nivalis, from which the new species differs externally in the smaller size, the
less elongate forewing with a less elongate apex and a more angular tornus,
the brownish-grey body and forewing ground colour (vs pale brown in D. niva-
lis), the more zigzagged antemedial line, the smaller dark core of the reniform
marking, and the less curved postmedial line. The male genital capsules of the
two species are similar but in D. ultramontana sp. nov. the uncus is shorter and
somewhat broader and the harpe is more distally dilated than in D. nivalis. In
the vesica, the new species has two bunch-like clusters of cornuti (vs a single
cluster in D. nivalis), and a shorter ventral diverticulum. A diagnostic compar-
ison with another morphologically similar species, the sympatric D. /uxuriosa
sp. nov. is provided above in the diagnosis of the latter. The female is unknown.

Description. External morphology of adults (Figs 35, 36). Forewing length
11.0-11.5 mm in males. Male antenna shortly bipectinate. Body dark brown-
ish-grey with admixture of pale grey scales in head and thorax and intense
admixture of brown in abdomen laterally and distally. Forewing elongate
with almost straight costal and moderately convex anal and outer margins.
Forewing ground colour brownish-grey with blackish-grey suffusion. Pattern
elements blackish. Costal margin with series of irregular blackish spots.

Note. In the original description, Hreblay and Ronkay (1995) listed a D. (Tat-
sipolia) female specimen as paratype of D. nivalis and illustrated its genitalia.
However, as it originates from a non-type locality, its conspecificity to the holo-
type is doubtful.

Diagnosis. The forewing length is 13.0 mm in the male holotype. The species
is morphologically similar to D. ultramontana sp. nov. and a detailed compari-
son is provided above in the diagnosis of the latter species.

Distribution. The species is currently known only from its type locality in Xi-
zang, China.

The D. (T.) kita species group

Diagnosis. The male genitalia of the species group are characterised by the
combination of the basally dilated and heavily sclerotised harpe (whereas it is
slender and clavate in the D. nivalis and reduced in the D. vignai species groups)
and the reduction of the distal ampulla, which is well-developed in two other
species groups of D. (Tatsipolia). The female genitalia are unknown.

3700-4200 m’).

Type material examined. Holotype (Figs 38, 58): 3, “China, W.Sichuan | Kang-
ding, near | Zheduo Pass | 3700-4200 m., | 14.10.2009. | Floriani&Saldaitis

Behounek, 2011” / “coll. G. BEHOUNEK | Grafing bei Miinchen” / “BC ZSM Lep
35678” (ZSM).

Diagnosis. The forewing length is 11.0 mm in the male holotype. Dasypolia
kita is easily distinguishable from similar species by the bronze-brown thorax
and forewing ground colour and the strongly bipectinate male antenna, which
is similar only to D. brandstetteri. The key genital differences from other species
in Tatsipolia are discussed above in the diagnosis of the D. kita species group.
The female is unknown.

Distribution. The species is currently known only from its type locality in
western Sichuan Province, China.
