The rostrum is nearly 1.5 to 2.0 times of the carapace length, it is armed dorsally at its basal end with usually 5 teeth, three or four of which are movable and very small and stand close together on the gastric crest, with two large isolated ones just in front of them, ventrally it is armed throughout, beyond the antennular peduncle, with a series of distant teeth not concealed by setae to the number of from 4 to 8; the 6th abdominal tergum is not quite twice as long as the 5th; there is no distinct ocellus on the dorsal margin of the eye; 1st perepods are not shorter than the external maxillipeds, 2nd perepods in the male alone are very slightly unequal in length: one of them reaches almost to the other very slightly beyond the tips of the external maxillipeds ( Alcock 1901).

Distribution. Arabian Sea, off the south and south-west coast of India, Bay of Bengal, Andaman Sea, Indonesia, Japan and Philippines; at depths of 496–1092 m ( Alcock 1901; Holthuis 1980; De Grave & Fransen 2011).
