See text Hexapus is a genus of crabs in the family Hexapodidae.

It contains only three extant species found in the Indo-West Pacific.

Like other members of the family, these crabs are easily recognizable due to the complete absence of the last pair of walking legs (pereiopods).

They thus only have six walking legs (excluding the claws), unlike the usual eight.

Their carapace is subquadrate, wider than it is long, with a rounded anterior.
