TYPE MATERIAL OF STEGOCEPHALIDAE 
Fig.5 Andaniexis americana sp.nov., holotype. 
Birstein & Vinogradov, 1960, the anterior margin of pereopod 7 is 
slightly concave, while only two other known species, A. australis and 
A. gloriosa (see below), share its state of having just one nodular seta 
on inner plate of the maxilliped. Furthermore, the present species has 
coxa 4 ‘heart’-shaped, a character otherwise only found in A. gracilis, 
A. mimonectes Ruffo, 1975 and A. tridentata Ledoyer, 1986.

Andaniexis australis Ledoyer 1986: 953-954, fig. 375. (non A. 
australis K.H. Barnard, 1932) 
MATERIAL EXAMINED. Holotype, female 7mm, st. CH90 (see 
Ledoyer 1986). Paratypes 4 females, 7-10 mm, st. CH 87 (see 
Ledoyer 1986), 3716m. Additional material, immature 2,5 mm, st. 
DE 12 (see Ledoyer 1986), 2500m. 
DISTRIBUTION. Only known from the type locality (Madagascar). 
DESCRIPTION 
Rostrum very small. 
Antennae short. Antenna | shorter than antenna 2; flagellum 5- 
articulate; accessory flagellum article 2 present. Antenna 2 peduncle 
(articles 3-5) as long as flagellum; article 3 short, about as long as 
broad; article 4 shorter than article 5. 
Epistome produced laterally, rectangular with a long ridge on 
each side; epistomal plate (medial keel) produced into a small 
elongate medial ridge exceeding along the entire epistome. 

3 
Mouthparts not elongate or pointed. 
Mandible incisor transverse; incisor smooth; left lacinia mobilis 
present, reduced, laterally straight, not conical. 
Maxilla 1 palp 2-articulate, rectangular, apex reaching beyond 
outer plate; outer plate distally rounded; ST in two parallel rows, 
first marginal and second submarginal, ST first row with 6 setae 
(ST1—5, ST7), ST 1 ordinary (similar to ST 2-4), gap between ST 5 
and ST 7 present, ST A-C present, all part of second row; inner plate 
with a weakly developed shoulder, setae pappose. 
Maxilla 2 ordinary, outer plate setae without distal hooks or cleft; 
inner plate setae row A covering the entire margin, clearly separated 
from row B, row A setae pappose, 3-4 first setae pectinate distally; 
row B setae proximally pappose, distally without cusps; row C 
present; row D present, 1—3 long setae distally, slender. 
Maxilliped palp 4-articulate, article 2 distally unproduced, dacty- 
lus distally simple (pointed); inner plate with 1 nodular setae; medial 
setae-row absent; distal setae-row present, setae simple; inner setae- 
row present, row reduced to one or two setae, conspicuously large 
and strong; outer plate outer setae-row present, submarginal, setae 
attached normally, setae long robust, straight; inner setae-row present, 
well developed, setae long robust, slender, appressed to outer setae- 
row; distal setae-group absent. 
Labrum very short; lobes symmetrical and reduced. 
Labium distally broad, oval. 
Coxal plates and basis of pereopods smooth. Coxae 1—3 contigu- 
ous. 
Pereopod | coxa not as deep as basis; propodus subovate. 
Pereopod 2 longer and thinner than pereopod 1; ischium elongate, 
ratio length:breadth exceeding 1.5; ischium distal posterior with 
margin plumose setae; propodus subrectangular, palm absent. 
Pereopod 4 coxa posteroventral lobe small, reaching about the 
base of the 6th pereon segment; basis anterior and posterior margins 
without long setae, without plumose setae on distal anterior and 
posterior margins; ischium without plumose setae on posterior distal 
margin. 
Pereopod 6 basis posteriorly expanded, expansion conspicuous, 
rounded posteriorly; without a row of long plumose setae. 
Pereopod 7 basis anterior margin straight, distally rounded. 
Oostegites on pereopods 2-5. 
Pleonites 1—3 dorsally smooth. 
Urosome: articulation between urosome segments 2 and 3 present. 
Uropod | peduncle longer than rami, outer ramus longer than inner. 
Uropod 2 peduncle longer than rami, outer ramus longer than inner. 
Uropod 3 peduncle longer than rami, outer ramus 2-articulate, outer 
ramus longer than inner. 
Telson longer than broad, shorter than peduncle uropod 3, entire, 
apically pointed, no submarginal setae on apically. 
MALE. Unknown. 
REMARKS. The present species is separated from all other mem- 
bers of Andaniexis by its relatively long and pointed telson. 
Furthermore, coxa | is relatively long and pointed (triangular), and 
is thus more similar to that of Andaniotes Stebbing, 1897. 
Unfortunately, the type material, borrowed from Museo Civico de 
Storia Naturale in Verona, Italy, disappeared in the mail. Thus, at 
present, there exists, to the authors’ knowledge, no registered material 
of this species.
