Fig. 19 Phippsia gibbosa, immature female, Bioice st.570. 
121 
about two thirds of the margin, clearly separated from row B, row A 
setae pappopectinate; row B setae proximally simple, distally with 
cusps present; row C present; row D present, expanded, row elon- 
gated towards and beyond row A, with many small cusps distally. 
Maxilliped palp 4-articulate, article 2 distal inner margin greatly 
produced, dactylus distally simple (pointed); inner plate with 2 
nodular setae; medial setae-row present, not reduced, vertical, setae 
pectinate; distal setae-row present, setae simple; inner setae-row 
present, row reduced to one or two setae, setae conspicuously large 
and strong; outer plate outer setae-row present, marginal, setae 
attached normally, setae short, strongly curved upwards (hooks); 
inner setae-row present, well developed, setae long robust, setae 
pappose, 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 smooth. Coxae 1—3 contigu- 
ous. 
Pereopod 1 coxa deeper than basis; propodus subrectangular. 
Pereopod 2 longer and thinner than pereopod 1; ischium not 
elongate, ratio length:breadth not exceeding 1.5, ischium distal 
posterior margin with plumose setae; propodus subrectangular, 
palm absent. 
Pereopod 4 coxa posteroventral lobe very large, reaching beyond 
the base of the 7th pereon segment; basis anterior margin without 
long setae, posterior margin with long setae, without plumose setae 
on distal anterior and posterior margins; ischium with plumose setae 
on posterior distal margin. 
Pereopod 6 basis posteriorly unexpanded, with a row of long 
plumose setae. 
Pereopod 7 basis anterior margin straight, 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 as long as rami, outer ramus shorter than inner. 
Uropod 3 peduncle longer than half the length of rami, outer ramus 
2-articulate, outer ramus shorter than inner. 
Telson longer than broad, longer than peduncle uropod 3, cleft; 
apically rounded, no submarginal setae on apex of each lobe. 
MALE. Unknown. 
REMARKS. Records at The Natural History Museum, London (see 
also Thurston & Allen, 1969) state that a type specimen of the 
present species is stored there, but that the validity of its status as a 
syntype is doubtful. The specimen in question was collected by 
G.O.Sars from the west coast of Norway, but the absence of a date 
leaves some doubt as to its type status. 
The present species is easily distinguished from all other 
stegocephalid species due to its peculiar gibbous pleonite 3. For a 
revision of this genus, see Berge & Vader (2000).
