Diagnosis. Carapace anterolateral lobe acute, prominent. Antenna peduncle exceeding antennule peduncle by half of article 5. Eyestalk distal lobes triangular, rounded, diverging, or truncate, with rounded distal margin, sometimes with dorsal ridge. Major cheliped merus lower margin with narrow straight dentate blade over proximal three-quarters; palm tuberculate on lateral and distal mesial faces in larger individuals; gape simple; fixed finger cutting edge smooth; dactylus cutting edge obscurely tuberculate, with notch near midpoint. Uropodal endopod posterior margin decidedly oblique, angle with anterior margin about 40°. Telson tapering from base to continuous rounded posterolateral margin. Maximum cl. 24.4 mm.

Distribution. Western, Central and Eastern Indo-Pacific ( Saudi Arabia, NE Australia, Indonesia [type locality: Ambon], Papua New Guinea, Philippines, Mariana Is, French Polynesia); shallow sand flats.

Remarks. The larger specimens agree well with the redescription of this species by Dworschak (2011a). It is notable for the slightly upturned anterolateral carapace spines and the concave anterior margin of the uropodal exopod. In the molecular phylogram based on nuclear and mitochondrial genes ( Robles et al., 2020: fig. 4) eight individuals fell into three subclades: two from Madang, Papua New Guinea; two others also from Madang with a third from the Philippines; and two from Nusa I., Papua New Guinea, with a third from Queensland. Clades 2 and 3 are sister clades. No consistent morphological differences could be found between them, supporting the synonymy of C. denticulatus with C. vigilax .
