Andaman Sea, RV “Dr. Fridtjof Nansen”, stn 68, 14°06.22’N, 94°31.81’E, 457 m, 4 April 2015, beam trawl, 1 female (cl 37.5 mm), NTOU M02040. Description. Body strongly compressed laterally; integument rather firm, glabrous. Rostrum (Fig. 1 A, B) relatively small for genus, arising posterior to frontal margin of carapace, terminating in tiny spine directed forward and falling short of carapace frontal margin; anterior margin slightly sinuous. Carapace (Fig. 1 A, B) 2.1 times longer than deep; rostrum and postrostral region strongly compressed laterally; dorsal margin gently sinuous in lateral view, distinctly carinate in anterior 0.8 (edge of dorsal carina blunt), rounded in posterior 0.2; frontal margin slightly convex; lateral face with obsolete ridge extending from postorbital region to hepatic region; hepatic region with very shallow depression; branchial region with clearly demarcated longitudinal ridge (branchial ridge) extending from hepatic region to near posterolateral margin and short branched ridge extending obliquely from hepatic region; suborbital lobe roundly triangular; antennal lobe obtusely triangular; branchiostegal spine small, submarginal, shortly buttressed, tip overreaching anterolateral margin of carapace; branchiostegal sinus broad, deep. Pleon (Fig. 1 C) with somite 1 rounded dorsally (Fig. 1 D); terga of pleomeres 2 (Fig. 1 D) and 3 (Fig. 1 E) generally flattened, lateral margins delimited by blunt carinae; tergum of pleomere 4 slightly ... |
