group. Head capsule in full-face view usually appears about as long as broad, CI 101 or less. Mandibles smooth with scattered small punctures. Masticatory margin of mandible with 7-10 small, low indistinct teeth, reduced to mere crenulations or even more or less smooth when worn. Basal angle of mandible rounded, usually with a very small basal tooth visible but sometimes indistinct or vestigial, or with a slightly accentuated basal angle. Dorsum of head with scattered punctures on smooth cuticle; on sides of head the punctures denser than on dorsum, and also with weak striation within the antennal fossae and on the sides, especially anteriorly. Metatibia with only normal setae dorsally but its anterior surface, at the apex and approximately opposite the pectinate spur, with two much stouter and sometimes more darkly coloured spiniform seta whose bases are close together. With mesosoma in profile the dorsal outline of the propodeum is abruptly angled downward from the mesonotum, so that its anterior portion forms a steep slope. Petiole node in dorsal view broader than long. Pronotal dorsum, and anterior mesonotum, with a few widely scattered broad, shallow punctures that may be almost effaced. Pronotum dorsally also usually with variable weak oblique or arched faint disorganised sculpture; almost effaced in some specimens. Colour yellow to light brownish yellow.
