Fig. 20. Lanceola sphaerica Vinogradov, male (after Vinogradov, 1970). 



The integument is very thin and transparent. The pereon bulges 

 notably, being almost spherical in the females. The pereon is short and 

 broad. A rostrum is absent. The eyes are small, poorly discernible in 

 fixed specimens. 



The proximal segment of the flagellum of antennae I is elongated- 

 conical, weakly armed on the anterior margin; the distal segments are 

 well developed. Antennae II of the male are slightly longer than anten- 

 nae I, their four-articled flagellum twice longer than the peduncle. The 

 mandibles have a thin palp, slightly larger than the mandibular body. 

 The outer lobes of the maxillipeds are well developed and armed with 

 strong setae, the inner lobes small, tapering apically. 



Pereopods I and II are structured as in L. clausi; their 2nd segment 

 is broad — in pereopods I the width of the 2nd segment is 1/2 and in pere- 

 opods II slightly less than 1/2 its length. Pereopods III are strong, the 

 2nd segment slighdy shorter than the 4th and 5th together and somewhat 

 longer than the 6th; the 4th segment is broadened distally; the 5th seg- 

 ment is linear, almost 1 .5 times as long as the 4th, and in the male richly
