Description
Anterolateral teeth of full grown specimens obtuse, areolae of carapace smooth or sparingly eroded.

Carapace convex and sharply defined by clean-cut furrows; their surface is smooth but dull, owing to close microscopic granulation. Front bilobed, the outer angle in each lobe forming a distinct little lobule. The four teeth of the antero-lateral border ae sharply concial. Chelipeds unequal, but not greatly so, very finely granular. Arm with the anterior border rather strongly serrated, and with numerous pustule like tubercles along the posterior border. Upper and outer surface of wrist and upper as well as a small part of inner and a larger part of outer surface of hand, covered with well spaced pustule like tubercles, those on the outer surface of hand being in longitudinal series; inner angle of wrist strongly pronounced with bifid tip. Legs with finely granular surface, sharply granular on the dorsal aspect, where there are some long scattered hairs. Upper edge of meropodites with 1 row of spinules, upper border of carpopodiles with 3 rows, of propodites with 2 rows.

Mostly found in live corals of Acropora and Montipora species and also in the dead corals of Pocillopora damicornis.
