as pygofer apex; style extending posteriorly approximately as far as apex of 
connective which is subtriangular with apical angle produced; aedeagus with 
shaft slender, very slightly decurved, truncate apically; paraphyses with stalk 
shorter than rami which are abruptly curved anterodorsally at apices. 
Color of crown red, with broad median stripe and a marginal area before 
each eye, ivory; pronotum and scutellum tan, the former tinged with red 
along anterior and anterolateral margins; forewing marked as in L. paraensis, 
n. sp. (below); face, thoracic pleura, and legs, yellow. 
Holotype male, Rio Uaupes, Taracud, (Brazil) April 7, (Roman). One ad- 
ditional male, Fonteboa, Amazonas (RMS). 
L. insperata, n. sp., is very closely similar to the following three species, with 
which it forms a complex. The aedeagus, only slightly decurved and without a 
convexity on the ventral margin in lateral view, and the erect paraphyses with 
their abruptly curved apices, are a combination of characters which are dis- 
tinctive for insperata. In the specimen not illustrated, the stalk of the para- 
physes is broader than in the type (see fig. 2784), approaching the condition 
found in L. comitis, n. sp. 
Ladoffa comitis, NEW SPECIES 
FIGURE 279, PAGE 347 
Length of male 6.4-7.0 mm, of female 6.4 mm. Head with median length of 
crown from three-fourths to slightly more than eight-tenths interocular width 
and from four-tenths to less than one-half transocular width; clypeus slightly 
flattened dorsomedially, muscle impressions not very distinct. Male pygofer 
well produced, apical margin regularly convex, without processes, with inter- 
spersed long and short macrosetae on posterior half of disk; plates and styles 
as in L. insperata, n. sp. (above); aedeagus with shaft slender, more decurved 
than in insperata, usually with an anteapical convexity on ventral margin in 
lateral view, with an apicoventral angle; paraphyses symmetrical with stalk 
longer than rami and very broad, rami extending straight posterodorsad in 
lateral view, apices curved very slightly ventrally in lateral view in some speci- 
mens, never curved dorsally. 
Color of crown as in insperata; pronotum as in insperata, or red with a short 
median stripe anteriorly, a pair of short discal longitudinal stripes, and the 
lateral margins dull yellow; scutellum dull yellow, tinged with red apically; 
forewing marked as in L. paraensis, n. sp. (below). Face, thoracic pleura, and 
legs, yellow. 
Holotype male, an additional male, and one female, Maroni River, French 
Guiana (NCS). Two males, Barro do Tapirape, Mato Grosso, Brazil, Decem- 
ber 10, 1962 (B. Malkin) (CAS). One male and one female near Mazaruni 
Head, Pakaraima Mountains, British Guiana, 1932 (J. G. Myers) and one 
male, Monkey Jump, Essequebo River, British Guiana, October 11, 1929 
(Oxford University Expedition) (BM). Holotype on indefinite loan to USNM. 
L. comitis, n. sp., is closely related to insperata, from which it can be dis- 
tinguished most readily by the paraphyses in which the stalk is longer than
