Alcock, 1898
Dorsal regions of the carapace sometimes well delineated, sometimes poorly indicated, granular or smooth. Behind the exorbital angle, presence, at the most, of four antero-lateral teeth (sometimes only two or three), generally feeble, often eroded at their tips. Front: its breadth more than one third the maximum width of the carapace, hardly projecting, either nearly straight or quadrilobed, with two large submedian lobes and two small lateral lobules. Antennules folded transversely. Basal article of the antennae without (or with a feeble) external antero-lateral lobule; antennal flagellum excluded from the orbit. Chelipeds with the extremities of fingers rounded and spoon-shaped. Ambulatory legs with a dactylo-propodal articulation formed by a rounded prolongation of the propodal lateral margin sliding against and beneath a projecting button situated proximally on the lateral margin of the dactylus.
