Description
Worker

Bingham (1903): Reddish yellow, the mandibles, antennae and legs slightly paler; smooth and shining; pilosity sparse, the legs with the hairs oblique. Head rectangular, longer than broad, posteriorly transverse, the lateral angles rounded; mandibles narrow, the masticatory margin oblique, armed with 4 teeth; clypeus short, the medial carinae strongly convergent above; antennae ll-jointed, rather short, the scape not reaching the top of the head; eyes placed below the middle on the sides of the head. Thorax: the pro-mesonotum comparatively large, convex, the meso-metanotal suture deeply impressed, the thorax constricted at the suture; the basal portion of the metanotum above rectangular, rather flat. Pedicel: the 1st node cuneiform, higher than the 2nd, rounded above; the 2nd node subglobose, broader than long, broader than the 1st node; abdomen elongate, oval.

Length: 1.5 mm
