Carapace usually squarish, often with oblique or transverse ridges. Front broader than eyes, usually without teeth, if teeth or lobes are present these are even in number. Ventral margin of orbit runs downwards toward buccal cavity. Anterolateral margin of carapace with at most 2 teeth behind orbit. Pterygostomian region with network-like pattern of very short stiff setae. Rhomboidal gap between third maxillipeds with mandibles exposed, merus and ischium of third maxillipeds with oblique ridge; posterior 4 pairs of legs similar, their dactyli with conspicuous spines. Male abdomen occupying all space between bases of fifth legs. Semiterrestrial, typical inhabitants of soft-sediment littoral habitats like marshes and mangroves.
