Head appearing subquadratic in front view. Mandible weakly striate, with four teeth, apical and subapical teeth large, basal two teeth smaller. Scape exceeding posterior corner of head, with appressed setae, each of which is as long as width of scape. Compound eye large and slightly projecting beyond lateral margin of head in full face view.
Ventrolateral katepisternal ridge indistinct posteriorly. Propodeal spine long and stout; length greater than spiracle, directed upward, dorsum higher than anterior propodeum in lateral view. Propodeal spiracle large, touching to propodeal declivity in lateral view, directed laterally.

Petiolar spiracle large, as large as half of propodeal spiracle, directed downward. Postpetiole bilobed with longitudinal median sulcus. Postpetiole wider than petiole in dorsal view.
Integument essentially smooth and shiny. Clypeus smooth and shiny without rugulae. Malar regions generally smooth. Dorsal surface of promesonotum smooth and shiny. Lateral surface of pronotum smooth and shiny. Mesopleuron and lateral propodeum generally shiny, but with feable rugulae. Dorsal surface of propodeum smooth and shiny.
Erect pilosity almost absent. Dorsum of head, clypeus and mesosoma with short and appressed setae sparsely. Clypeus with one pair of longer setae on anteriormost portion, directed medially. Anterior clypeal margin with two pairs of longer setae, mixed with some shorter setae on sides. No erect setae on pronotal shoulder. Posterolateral tubercle with some decumbent to appressed shorter setae. Ventral surface of petiole with appressed setae. Postpetiole with some shorter setae posteriorly.
