Genus Xenograpsus

Takeda & Kurata, 1977

Carapace rather quadrate, slightly broader than long, and moderately convex in both directions. Dorsum uneven without distinct areolation and with oblique striae on postero-lateral surface. Front about one-third as broad as carapace, bearing a median small interruption. Infraorbital floor with a deep notch near its inner lobe. Antennal flagellum including a distal aesthete about equal to, or slightly longer than, major diametre of orbit. Third maxillipeds broad and completely closing buccal cavern; outer border of merus generally convex throughout its length; exopod narrow. Antero-lateral border of carapace with an indistinct incision behind external orbital angle, and postero-lateral border nearly longitudinal.
Chelipeds stout in male and much smaller in female. Palm bulged. Fingers stout with deeply excavated inner surfaces; distal part of cutting edges each with a horny marginal reinforcement and a tuft of stiff setae. Ambulatory legs rather stout and depressed with granulated borders. Distal four segments of first three pairs with longitudinal ridges and rows of hairs. Male abdomen narrow with elongated terminal segment. Male first pleopod rather stout and not heavily calcified, bearing a subdistal outgrowth and a distal marginal horny fringe nearly disguised by setae. (Takeda & Kurata, 1977)
