Description. -Body stout (Figure 43), integument 

 moderately thick, firm. Carapace with restricted 

 pubescent areas, setae dense and long at base of 

 rostrum, on pterygostomian region, and in patch 

 extending from orbital margin to epigastric tooth; 

 minute, sparsely set setae on dorsum and hepatic 

 region. Abdomen polished, almost entirely naked 

 except for setae on posterior part of dorsal keel; 

 telson and mesial ramus of uropod rather densely 

 pubescent. Rostrum short, its length 0.20-0.25 

 that of carapace, falling short of distal margin of 

 first antennular article, almost horizontal, with 

 dorsal margin straight and ventral margin 

 strongly convex, with subapical concavity giving 

 rise to saber-shaped tip; latter almost 0.4 length 

 of rostrum. Rostral plus epigastric teeth 5-7 (mode 

 6; N = 60), base of third rostral tooth at 

 level of orbital margin. Adrostral carina extend- 

 ing from orbital margin to ultimate tooth; more 

 dorsal barely perceptible carina extending from
