Diagnosis (modified from Turner, 1910)

Length 15-25 mm; colour brown-yellow and black; body moderately covered in golden setae; head of a female entirely brown-yellow; head of male brown-yellow with a black area in vertex; pronotum and mesoscutum brown-yellow; propodeum with two half-tubercles; propodeum black in females, brown-yellow in males; first metasomal segment black in females, brown-yellow with apical darkening in males.

Female

Colouration. Head brown-yellow; mesosoma brown-yellow (pronotum, tegula, and mesoscutum) and black (scutellum and propodeum); tibiae and tarsi brown-yellow, femora black basally, brown-yellow apically; first metasomal segment black, second metasomal segment onward brown-yellow.

Head. Head slightly wider than long, TFD/FD = 1.12; posterior ocelli closer to each other than to the compound eye, POL: OOL = 0.83; frons with the median line reaching median ocellus; apical margin of clypeus slightly concave; clypeus

medium, clypeus length: width = 2; labrum on same plain as clypeus slightly exposed beneath; malar space very short, almost non-existent; first flagellar segment slightly longer the second.

Mesosoma. Moderate pubescence, pronotum relatively short, with a clear median line, its posterior margin convergent towards median line; metanotum without knob; propodeum wrinkled across with a very weak median line, without any prominent tubercles (half-tuberculate); the dorsal edge of the hind tibia with spine-bearing tooth-like elevations; tarsal

claws dentate.

Metasoma. Metasoma polished, sparsely punctate, pygidium covered by short, abundant golden setae, metasoma 1.05x length of mesosoma.

Male

Similar to females except for differences described here: head bears black area between compound eyes; propodeum and first metasomal segment brown-yellow; hind tibiae without serration with short spines; tarsal claws bifid; body size slightly smaller.
