Rafinesque, 1815

Front narrow, deflexed; commonly a mere lobe along the long eyestalk. Interantennular septum broad. Antennular flagellum small or rudimentary, folding obliquely or almost vertically. Third maxillipeds completely closing the buccal cavern; exopodite inconspicuous but not, or not entirely, concealed, and with or without flagellum. Chelipeds remarkably unequal either in both sexes or in the male only. Between the bases of P3 and P4 an orifice or recess, the edge of which is thickly fringed with hair. (Guinot 1998)
