Rostrum evenly tapering to rounded apex, 1.4 times as long as wide; lateral margins smooth. Carapace median gastric carina sharply delimited, unarmed; submedian gastric carinae absent; lateral gastric carinae distinct, diverging posteriorly without constriction; dorsum with scattered thin setae and a pair of tufts of setae on cardiac region. Telson posterior margin truncate, with tiny median spine. Major cheliped merus lower margin unarmed; palm not wider distally at midpoint; palm lateral and mesial faces with scattered tubercles; palm distolateral margin without teeth in shallow gape; fixed finger occlusal margin with 2 rounded teeth in proximal half and row of much smaller, blunt teeth in distal half, without conspicuous notch; dactylus occlusal margin with blunt tooth proximally, shallow concavity and smooth distal part. Minor cheliped palm distolateral margin with small acute tooth at base of dactylus; fixed finger occlusal margin finely denticulate. Pereopods 3–5 dactyli with few spiniform setae on lateral surfaces.
