Ocular peduncle lacking distinct anterior lobe. Cornea with distal dorsal tubercle.

Cheliped (Figure 76c) of adult female slender, fingers, measured dorsally, longer than palm, latter with row of spinules dorsally. Merus with 2 prominent dorsal tubercles.

Dactylus of second pereiopod slender, slightly curved distally, apex broken; merus shorter than carapace. Merus of each walking leg with blunt, unarmed dorsal projection (Figure 76d).

Rostrum (Figure 77a,e) short, overreaching base but falling short of middle of fifth article of antennal peduncle, ornamented with curved hairs. Apices of rostral teeth divergent in some specimens. Rostrum slightly upturned dorsally (Figure 77b). Nuchal region usually with lateral spinule or tubercle, visible in dorsal view. Protogastric region smooth, lacking dorsal tubercles medially. Hepatic regions each with low, conical prominence dorsally. Hepatic lobes each with apical spinule, flanked mesially with spine on anterior margin in some specimens. Gastric and cardiac regions each with low, conical prominence. Branchial regions with poorly marked prominences: 1 low, rounded epibranchial, 1 broad dorsal mesobranchial, 1 low metabranchial near posterior margin, and sharp tubercles laterally. Anterolateral margins with sharp, anteroventrally directed spine posterior to hepatic lobe.

Basal antennal segment (Figure 77b) with 1–3 spinules or sharp tubercles, anteriormost largest. Distal article of antennal peduncle about 3 times as long as penultimate. Epistome with spinule near opening of antennal gland, occasionally with spinule anteriorly near base of antenna.

Ocular peduncles lacking distinct anterior lobe. Cornea with distinct dorsal tubercle.

Chelipeds of adult males larger and more robust than in females. Fingers as long as palm, latter with row of spinules dorsally. Merus with 3 erect dorsal spines or lobes.
