ST7), ST 1 conspicuously enlarged, gap between ST 5 and ST 7 
present; ST A present, located distally, part of first row; ST B—C 
present, part of second row, ST D absent; inner plate without a well 
developed shoulder, setae pappose. 
Maxilla 2 gaping and geniculate, outer plate setae with distal 
hooks present, distal cleft absent; inner plate setae row A covering 
the entire margin, clearly separated from row B, row A setae 
pappopectinate; row B setae proximally pappose, distally with 
cusps present; row C present; row D present, 1—3 long setae distally, 
setae with many small cusps distally. 
Maxilliped palp 4-articulate, article 2 distal inner margin weakly 
produced, dactylus distally simple (pointed); inner plate with 2 
nodular; medial setae-row present, reduced to one or two setae but 
differentiated from distal row, transverse, setae pectinate; distal 
setae-row present, setae simple; inner setae-row present, setae not 
conspicuously large; outer plate outer setae-row present, marginal, 
setae attached in a deep hollow, setae short, strongly curved upwards 
(hooks); inner setae-row present but strongly reduced, setae short 
simple and slender, proximally parallel to outer, distally transverse; 
distal setae-group present, setae attached in a deep hollow, setae 
short simple. 
Labrum elongate; lobes asymmetrical, right lobe not reduced, left 
lobe reduced. 
Labium distally narrowing. 
Coxal plates and basis of pereopods covered with simple setae. 
Coxae |—3 contiguous.

Fig. 25 Stegocephalides attingens, female (8mm) cotype. 
Pereopod | coxa deeper than basis; propodus subovate. 
Pereopod 2 general appearance like pereopod 1; ischium not 
elongate, ratio length:breadth not exceeding 1.5; ischium distal 
posterior margin plumose setae present; propodus subrectangular; 
palm absent. 
Pereopod 4 coxa posteroventral lobe large, reaching about the 
base of the 7th pereon segment; basis anterior margin without long 
setae, posterior margin with long setae, plumose setae on distal 
anterior margin, no plumose setae on distal posterior margin; is- 
chium with plumose setae on posterior distal margin. 
Pereopod 6 basis posteriorly unexpanded, with a row of long 
plumose setae present. 
Pereopod 7 basis anterior margin straight, distally pointed and 
acute, with medial row of long setae. 
Oostegites on pereopods 2-5, but strongly reduced on pereopod 
2. Gills on pereopods 2-7. 
Pleonites 1-3 dorsally smooth. 
Urosome: articulation between urosome segments 2 and 3 absent. 
Uropod | peduncle longer than rami, outer ramus as long as inner. 
Uropod 2 peduncle longer than rami, outer ramus shorter than inner. 
Uropod 3 peduncle longer than half the length of rami, outer ramus 
l-articulate, outer ramus longer than inner. 
Telson longer than broad, longer than peduncle uropod 3, cleft, 
apically pointed, submarginal setae on apex of each lobe. 
MALE. Pereopod 2 propodus larger in males than in females. 
Urosome ordinary (similar to females). 
REMARKS. The distally acute basis on pereopod 7 is a character 
state only shared with Stegocephaloides auratus (Sars, 1883), but S.
