Diagnosis: Postorbital region with two long and one short striae; exopod of third maxilliped reaches proximal third of merus. Propodus of 2nd ambulatory leg with one row of spinules dorsally. First pleopod stout; penultimate segment 3.8 times as long as ultimate; ultimate segment straight; synovial membrane 1.8 times as long as broad.

Description of holotype: The carapace is quadrangular and distinctly flattened excluding the frontal and the orbital regions. The length of the carapace is 0.86 times its greatest breadth and the depth is slightly more than the length of the carapace. The postfrontal region bears crenulate, short striae. The postorbital region has two long and one short transverse striae. The epibranchial region bears some smooth tubercles and short striae. The antero-lateral margin of the carapace is crenulate and its posterior margin ends slightly inwards to the dorsum of the carapace. The postero-lateral margin and the subbranchial region bear many short striae. The frontal region bears many tubercles, it is 0.33 times as broad as the carapace, and 0.43 times the distance between the external orbital teeth. The orbital region is narrow and is distinctly crenulate on the margin. Between the suborbital and the subhepatic regions have short striae. The pterygostomial region bears many short striae on the upper part and is smooth on the lower part. The exopod of the third maxilliped reaches the proximal third of the merus; the propodus is slightly longer than broad.
The 6th abdominal segment is 0.56 times as long as broad, and slightly longer than the 7th; the 7th segment is 0.60 times as long as broad. The first pleopod is stout; the penultimate segment is 3.8 times the length of the ultimate; the ultimate segment is straight; the synovial membrane is 1.8 times as long as broad.
The chelipeds are similar and subequal, but the right is slightly longer than the left. The palm bears many crenulate short striae. In the right cheliped the palm is 0.91 times as long as broad and 0.67 times the length of the dactylus. The fingers are slender, not gaping with a series of many small teeth on the cutting edges. The ambulatory legs are slender and have sparsely short hairs on the dactylus and the propodus. The 2nd ambulatory leg is 1.7 times the breadth of the carapace; the propodus bears 2.7 times as long as broad. The propodus bears one row of spinules dorsally and two rows of spinules ventrally; the dactylus bears each two rows of spinules ventrally and dorsally. Ten spinules are present on the ventral margin of the dactylus. (Minei, 1973)
