Compound eyes not projecting from lateral margin of head, the outer margin of eye almost flush with head capsule in full face view. Scape not reaching posterior corner of head, the scape with standing setae.

Anterior margin of pronotal collar almost straight in dorsal view. Metanotal groove deep and distinct with longitudinal rugulae. Propodeal spines as long as the diameter of propodeal spiracles. Anterior margin of metapleural gland bulla not reaching anterior margin of propodeal spiracle.

Petiole in dorsal view broader anteriorly than posteriorly. Postpetiole weakly bilobed, but without distinct longitudinal median sulcus. Subpetiolar and subpostpetiolar processes undeveloped.

Malar region near clypeal margin of head with rugulae. Clypeus relatively smooth and shining, but with feeble rugulae. Dorsal face of mesosoma almost smooth and shining. Dorsolateral face of pronotum with feeble rugulae in dorsal view. Lateral surface of pronotum smooth and shining. Higher and lower portions of mesopleuron weakly sculptured.

Standing setae abundant. Dorsal face of head, clypeus and mesosoma with standing setae. Fourth abdominal tergite with sparse standing setae.

Type Material
Hosoishi and Ogata (2012) - LECTOTYPE worker (bottom and tip specimen of six on one pin) (by present designation) and five paralectotype workers from VIETNAM: Lang Bian, Cochinchine [South Vietnam] (Bouvard) [examined].
