Description
Worker

Bingham (1903): Closely resembles C. risii, Forel, but is larger, the mandibles are striate (only punctate in C. risii), the proportion of the joints of the flagellum of the antennae is different, and the apex of the same is not so incrassate as in C. risii. Black, the mandibles and antennas fuscous ; the legs and extreme apex of the abdomen reddish yellow; the whole insect covered with soft short, sparsely scattered, erect white hairs. Head anteriorly sparsely, posteriorly cribrately punctured. Thorax rounded above, submargined anteriorly ; the basal portion of the metanotum separated from the obliquely truncate apical portion by a fine shining carina, not so marked and distinct above as in C. risii; legs, pedicel, and abdomen as in C. risii.

Length: 7 - 7.5 mm
