Rostrum with a dorsal rostral tooth. Outer margin of second segment of antenna as a rule with 6 teeth (apical tooth not included).
Distance between the orbit and the anterolateral angle of carapace 2/5 or less than 2/5 of the distance between two orbits. The posterior of the two lateral teeth of the carapace before cervical incision smaller, but not very much smaller than the anterior. Transverse groove which separates two parts of abdominal somites narrow and filled with many short hairs. The first abdominal somite with 3 to 5 not sharply defined spots on posterior margin: no second row of spots present. Median carinae of second and third abdominal somites usually almost level with surface of somites. Anterior part of second to fifth abdominal somites with reticular pattern of shallow and narrow grooves.

Central Pacific Ocean from Kapingamarangi through the Marshall, Gilbert and Phoenix Islands to the Marquesas.
Habitat and Biology:
In shallow waters, in or near reefs.
Known carapace lengths vary between 2.5 and 7 cm Maximum total body length about 15 cm.
Interest to Fisheries:
No information available, but judging by the fact that all other species of the genus are used as food, the same is expected for the present one.
