The first two somites of the pereon are very small, their total length 

 equal to that of the third somite. The coxal plates are separated from the 

 pereon except for the coxae of pereopods VII. Pereopods I-II are very 

 small and have poorly developed chelae. Pereopods III-IV are remark- 

 ably thin and relatively long, equal in length or somewhat longer than 

 pereopods V-VI. the 2nd-6th segments of pereopods V-VI are broadened 

 and the claws very small. Pereopods VII are small and have an oval flat 

 2nd segment and virgate distal segments; the total length of the latter is 

 less than or equal to the 2nd segment. 



The pleon is shorter than the pereon. The urosome is short; uro- 

 somite I is more than twice wider than long; the second (geminate) uro- 

 somite is approximately equal in length and width and slightly tapers 

 distally. The telson is roundish and fused with the last urosomite. The 

 rami of all the uropods are free.

Length of sexually mature crustaceans up to 17 mm. 



The head in females and young males is strongly bulged in the 

 proximal part and ventrally roundly projects downward and backward, 

 covering the neck; dorsally the neck remains visible; the occipital part of 

 the head is steeply elevated. The rostrum is rounded anteriorly, concave 

 ventrally, and dorsally forms a straight line with the proximal part of the 

 head occupied by the eyes (lateral view). The longer axis of the head 

 forms a small angle with the longitudinal axis of the body, imparting a 

 unique appearance to the crustacean. 



Pereopods I-II do not reach the middle of the 2nd segment of pere- 

 opods III; their 2nd segment is longer than the distal segments together; 

 the chelae formed by the process of the 5th segment and the 6th segment 

 are weak; the 5th segment is less broadened and its process in pereopods I 

 does not reach, in pereopods II reaches the base of the claw; often the 

 process is additionally ornamented with a group of short spiniform setae 

 at the base or on the inner side. Pereopods III-IV are unusually thin and 

 longer than the other legs. Pereopods III are longer than pereopods IV, 

 their 2nd segment the same length as the 4th-5th segments together; of 

 the distal segments, the 4th is the longest; the claws are very small; all 

 the segments are armed with short setae. Pereopods V-VI are identical 

 and have broadened segments, especially in pereopods V. The 2nd seg- 

 ment of pereopods V is 2.5-3 times longer than wide and narrow at the
