(Borradaile, 1903)
Carapace 1.9 times broader than long, regions ill-defined; dorsal surface covered with small flat granules barely visible to the naked eye, shallow, irregularly-shaped grooves and circular depressions present; prominent granule on dorsal surface posterior to the hepatic angle; triangular depression on region posterior to orbit; median longitudinal ridge very wide and indistinct; branchial regions mildly swollen, short row of transverse larger granules in between branchial regions; shallow, irregularly shaped, groove on either side of cardiac and intestinal regions; branchiostegite region finely granulated with no distinct granulated region; true posterior margin entire. Front slightly produced and moderately bibbed; margins of carapace with surrounding rim; margin of hepatic region beaded and protruded slightly to form obtuse angle, margin of sub-hepatic region protruded to form obtuse angle, with larger granules at the tip; deep, oblique granulated groove on ventral surface posterior to sub-hepatic angle. Basal segment of antennule occupies half of fossa when closed, margin of fossa with granules. Third maxillipeds covered with fine granules as on carapace; merus with pointed apex, outer edge with slight angle halfway down from apex; ischium 2 times longer than merus along inner margin, proximal third of inner edge lined by large granules. Inner surface of chelipeds more granular than outer surface; fingers 1.5 times longer than palm; inner surface of palm with 3 large granules close to proximal end; distal half of cutting edges of fingers with small denticulate teeth. Anterior edge of merus of last pair of legs lined with large granules; anterior and posterior edge of propodus with large, pointed granules; dactylus long and narrow, covered with small pointed granules. Abdomen covered with small granules and depressions as on carapace; terminal segment broadly triangular. (Tan & Ng, 1995)
