Diagnosis
Female
Integument dark brown to black, except flagellum dark brown and tegula yellowish brown (Fig. 1A–B). Wings brown with veins dark brown (Fig. 1B). Head, mesosoma (except the ventral surface) and anterior half of T1 with intense yellow slightly greenish pilosity, lighter on labrum and gena (Fig. 1A–B). The rest of the body with blackish hairs, except posterior apex of the femur of forelegs with some yellowish hairs (Fig. 1A–B). Clypeus coriaceous with coarse and dense punctation (Fig. 1A). Clypeal disc with an unpunctated area on upper half, without smooth longitudinal band. Labrum with the same punctation, but denser, without smooth basal margin. Terga and sterna, except T6 and S6, with very narrow smooth distal margin, wider on T4. Mandible with four apically acute teeth (Fig. 1A). Fourth teeth slightly larger than the third (Fig. 1A). Maxillary palpus 4-segmented. Malar area very narrow (Fig. 1A). Labrum semicircular (Fig. 1A). Inner orbits of compound eyes converging downward (Fig. 1A). Elaiospathes normally developed. Basitibial plate elliptical, with S-like secondary plate (Fig. 2A). S2–S4 projected in the middle. Apex of primary pygidial plate slightly rounded with the apex of the secondary plate open and slightly projected towards the distal edge of the primary plate (Fig. 2D).
Male
Similar to the female, except for the following characters: integument dark brown to black, except basal segments of the flagellum brown and apical segments slightly orange (Fig. 1C–D). Supraclypeal area, discs of clypeus and labrum yellow (Fig. 1C–D). Tegula yellowish brown. Clypeal disc with small unpunctated area on upper half, without smooth longitudinal band. Terga and sterna, except T7 and S6, with relatively broad light brown smooth distal margin, wider on T4. Mandible with three apically acute teeth (Fig. 1C). Distance between clypeus and compound eyes shorter than half of the shortest diameter of F1 (Fig. 1C). Apical margin of the hind tibia without tooth-like projection. Apical half of fore and middle basitarsi without a row of long, erect, slightly spatulate and curved setae similar to an elaiospathe. Pygidial plate absent.
