Wood-Mason, 1891
Monotypic genus, therefore definition of genus is repeated:
Carapace flattened, dorsal surface covered by a velvety tomentum, no spines or tubercles; frontal spine armed with a lateral spinule on either side and longer than pseudorostral spines; frontal, pseudorostral, and subhepatic spines are on the same plane. Chelipeds robust, but much shorter than the following ambulatory legs. Meri of second to fourth pereiopods broadened in their proximal two thirds. Proximoventral corner of propodus of fifth pereiopod not strongly produced, a number of spines both on ventral borders of propodus and dactylus. (Türkay 1995)
