TYPE MATERIAL OF STEGOCEPHALIDAE 

Fig. 2 Andaniexis australis, female cotype. 
Labrum very short; lobes symmetrical and reduced. 
Labium distally broad, oval. 
Coxal plates and basis of pereopods smooth; coxae 1-3 con- 
tiguous. 
Pereopod 1 coxa not as deep as basis; propodus subovate. 
Pereopod 2 longer and thinner than pereopod 1; ischium elongate, 
ratio length:breadth exceeding 1.5, posterior margin with long 
plumose setae distally; propodus subovate, 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, with plumose setae on distal anterior margin, no 
plumose setae on distal posterior margin; ischium with 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 concave, distally rounded, no 
medial row of setae. 
Oostegites on pereopods 2-5. 
Pleonites 1-3 dorsally smooth. 
Urosome: articulation between urosome segments 2 and 3 present. 
Uropod 1 peduncle longer than rami, outer ramus longer than inner. 
Uropod 2 peduncle longer than rami, outer ramus slightly longer 
than inner. Uropod 3 peduncle longer than rami, outer ramus 2- 
articulate, outer ramus equal to inner. 
Telson as long as broad, shorter than peduncle uropod 3, entire, 
apically pointed. 
Unknown. 
REMARKS. 
MALE. 
This species was originally described by K.H. Barnard

in 1932, and has later been redescribed by Barnard 1962, 1964) and 
Ledoyer (1986). However, neither of these redescriptions were 
made based upon the type material. Consequently, both Andaniexis 
americana sp.nov. (see below) and Andaniexis gloriosa sp. nov. (see 
below) were wrongly identified as A. australis s.s. 
The combination of a rectangular coxa 4, a concave anterior 
margin of pereopod 7 and the presence of only one nodular seta on 
the inner plate of the maxilliped is unique for this species within the 
genus (note: the last character is unknown for A. oculatus.). From 
the description of A. oculatus, it is not possible to separated A. 
australis from A. oculatus. However, until material of the latter has 
been made available for examination, the two species are not put into 
synonomy.
