Diagnosis

Carapace subhexagonal, moderately wider than broad or about as broad as long; not obviously convex in both directions; eyestalks short; anterolateral border divided into five or fewer teeth (including exorbital tooth), supra-orbital fissures reduced, infraorbital fissure reduced or absent. Basal antennal segment narrow, cylindrical, fixed or free, longer than broad, lying longitudinally; lobe on first maxilliped ('portunid lobe') inconspicuous. Chelipeds long and stout; usually without spines except for inner carpal spine. At least one pair of ambulatory legs longer than chelipeds; dactyli of last pair of legs mostly lanceolate or styliform. Male first gonopod without subterminal spines. (After Apel & Spiridonov 1998).
