Orbits very wide, deeply excavated, sometimes with small orbital tooth and notch, two orbital fissures, one of which is continuous with notch if present; fronto-orbital width/width ratio about 67–74 percent. Anterolateral margin short, bearing four or five spines including outer-orbital spine, last spine usually longest. Protogastric and hepatic regions with transverse ridges. Epibranchial region arcuate, extending axially from last anterolateral spine. Branchial regions weakly inflated. Posterolateral reentrant wide, well-developed. Chelae heterochelous, stout, fingers with large blunt denticles on occlusal surface. Dactyl of fifth pereipod paddle-like.
