but well noticeable; the 1st and 2nd segments are short; the 3rd is nar- 

 rower and long. Antennae II in females are four-segmented and slightly 

 longer than the peduncle of antennae I. 



The cutting edge of the left mandible is formed by two fully nonover- 

 lapping plates. Maxillae I have a broad inner lobe; the spines on the outer 

 lobe are small and weak. 



The outer lobe of the maxillae is narrower and shorter than the inner 

 lobe. The maxillipeds have broadly oval outer lobes armed on the inner 

 distal angle with a row of short setae; the inner lobes are longer than 

 half the length of the outer lobes and bear a row of short setae and one 

 strong apical seta each. 



Pereopods I and II have a slightly curved 5th segment; the dis- 

 tally slightly narrowing 6th segment in pereopods I is shorter, in pere- 

 opods II longer than the 5th segment, and bears numerous setae on both 

 the anterior and posterior margins and the distal surface (especially in 

 pereopods I). Pereopods III are longer than the preceding pairs, their 

 2nd segment much shorter than the 4th and 5th segments together; the 

 distally broadening 4th segment is equal to or slightly longer than the 

 oval 5th and slightly shorter than the thin 6th segment; the claws are 

 small and curved. Pereopods IV have roughly the same proportions but 

 their distal segments are stronger. Pereopods V-VII are roughly equal in 

 length (pereopods VII slightly shorter), thin, rod-shaped; the length of 

 their 2nd segment is roughly equal to the length of the 4th and 5th seg- 

 ments together; the long 4th segment is almost equal to or even longer 

 than the 5th and even shorter 6th segments together; the 6th segment has 

 a spoonshaped formation; the claws are retractile.
