Description
Size: 35-50 mm

Carapace with pterygostomian spine as large as antennal; rostrum always longer than carapace, with 11-16 dorsal teeth, of which 7-12 are on the elevated crest; lower margin with 7-16 teeth; carapace bluntly carinate mid-dorsally in its anterior half and bears 1 or 2 minute spinules behind basal crest of rostrum. Antennular peduncle hardly reaches to 2/3 length of antennal scale, the latter variable in form and usually more than thrice as long as broad. Third maxilliped falls short of apex of antennal scale.
Carpus of 1st pereopod a little shorter than chela; dactylus scarcely 2/3 length of palm. Merus of 2nd pereopod indistinctly divided into 7-11 segments, while the carpus is composed of 12-17. Palm of chela shorter than last carpal segment. Last 3 pairs of legs have a variable number of spines on the ventral side of merus. Fifth pair of legs extends to 2/3 or 3/4 length of antennal scale. Dactylus with a few spinules posteriorly.
Epipods short and rudimentary at base of first 4 pairs of pereopods and concealed from view by downward growth of pleurobranchs. Sixth abdominal somite is 1/4 longer than 5th. Telson about twice the length of 6th somite, has 2 pairs of dorsal spinules. It extends beyond distal end of uropods. There are no terminal spinules.
