Description
Carapace longer than broad and the rostrum well produced anteriorly. Medium size spine at the postero-lateral angle of each branchial region.

Carapace triangular, broad behind, as long as broad. The regions are elevated, and the median are separated from the branchial by deep furrows. All the regions are closely covered by rasp-like tubercles. The lateral borders are tubercular, and end posteriorly in a large spine directed outwards and somewhat backwards. The chelipeds are a little more than twice the length of the carapace, with the inner and outer borders serrated, and the upper surface covered with tubercles like those on the carapace. The ambulatory legs are slender and smooth. The epistome is sculptured, and is very deeply excavated in the middle line. The pterygostomian region is traversed by a canal running parallel with the buccal frame and the canal is perfectly smooth.
