(Borradaile, 1902)
Carapace subcircular or rather rounded pentagonal, the dorsal surface is thickly covered with granules and the regions fairly well delimited by narrow grooves, i.e. those corresponding to the regions of Xanthidae - 2M, 3M, 1P are especially well defined. Antero-lateral borders are indistinctly divided into two or three lobes, the margins of these lobes are marked with somewhat larger granules and fringed with feathered hairs. The front is extremely deflexed and marked with the median distinct notch, the free margins being fringed with hairs. The eyes are fixed and the cornea remains as a dot on the ventral surface. The antennal flagellum composed of about seven segments, the basal segment is furnished with very long feathered hairs around the whole surface. The chelipeds are symmetrical, wrist and palm are thickly covered with granules as on the carapace; the ambulatory legs are also very thickly fringed with long feathered hairs. (T. Sakai, 1939: 574)
