Head slightly longer than broad, with slightly convex sides and concave occipital border. Mandible with 4 teeth. Clypeus convex, anterior border broadly concave. Antennal scape extending beyond occipital border. Eye roundly convex, situated slightly behind the midlength of the sides of head. Pronotum broadly flat, slightly concave on its median part, laterally marginated, posterolateral corners bluntly projecting; promesonotal suture indistinct; mesopropodeal suture narrowly impressed; basal face of propodeum flat in profile view, as high as mesonotum; propoedeal spines broad at base, acute at tip, extending rightly backward. In dorsal view, petiolar node longer than broad, broader anteriorly than behind; post petiole with central groove. Gaster relatively broad.

Mandibles with longitudinal striations; head with longitudinal striations and densely coarse punctures. Alitrunk with densely coarse punctures, anterior margin of pronotum with transverse striations; mesonotum and propodeum with longitudinal striations. Petiole and postpetiole with fine striations. Gaster smooth and shining, with very fine reticulations. Erect hairs short and blunt, moderately dense. Antennal scapes and hind tibia with sparse suberect hairs.

Color brown. Head, dorsum of alitrunk darker.
