Antennae I in males are half the body length, the peduncle three- 

 segmented, and the flagellum has 14 segments. The conical 1st segment 

 of the flagellum has a convex posterior margin that is 1 .5 times longer 

 than the peduncle and its lower and inner surfaces bear numerous long 

 sensory setae. In females the peduncle of antennae I has two segments, 

 the flagellum is one-segmented, conical, and armed with a few sensory 

 setae. Antennae II in males are longer than antennae I, the segments of 

 the peduncle are short, and the flagellum is 13-segmented. Antennae II 

 in females are rudimentary and one-segmented. 



The mandibles have a very narrow denticulate cutting edge and an 

 accessory plate (on the left mandible); the dentate process is strong, 

 straight, with a tubercular masticatory surface. The palp of maxillae I 

 is broad, denticulate along the anterior margin, and has a strong short 

 spine on the inner distal angle. The inner lobe of maxillae li is broad and 

 short. The basal segment of the maxillipeds is notably longer than the 

 conical outer lobes, which have a smooth outer margin while the inner 

 margin bears a few setae in the distal part. 



The 5th segment of pereopods I is slightly broadened distally and the 

 anterior margin straightly truncate; the 6th segment is conical and half 

 as thick but 1.5 times longer than the 5th; the claw is strong and exceeds 

 half the length of the 6th segment; the 4th-6th segments bear numerous 

 short setae on the anterior surface. Pereopods II are somewhat longer 

 than pereopods I; the 5th segment is broadened distally but its lower 

 distal angle is stretched into a short spoon-shaped lobe armed along the 

 307 margin with numerous strong setae; the 3rd-6th segments bear numerous 

 short setae on the anterior surface. Pereopods IV are somewhat longer 

 than pereopods III; the 5th segment is almost twice longer than the 4th, 

 its anterior margin convex, the posterior margin straight; the 6th segment 

 tapers distally and is notably narrower and somewhat longer than the 5th 

 segment; the claw is almost straight and the proximal part of its posterior 

 margin denticulate; the posterior surface of the 5th and 6th segments is 

 covered with very minute setae. Pereopods V are equal to pereopods IV; 

 the 2nd segment is highly broadend, with convex anterior and posterior 

 margins, its anterior distal angle stretched into a small denticle; in the 

 narrow linear 6th segment the anterior distal angle resembles a straight 

 tooth, which forms a chela with the claw curving tightly toward the 

 anterior margin. Pereopods VI are slightly longer than pereopods V; the 

 2nd segment is slightly broadened and has a poorly developed posterior 

 lobe; the 5th segment is the same length as in pair V but the 6th seg- 

 ment longer; the claw is less than 1/4 the length of the 6th segment. 

 Pereopods VII are equal in length to pereopods V and the length ratio 

 of the segments identical.
