Description. Ocellar triangle with ca. 3–10 setae above ocellar setae. Frons yellowish brown to dark brown. Pedicel brownish to brown; first flagellomere brown. Clypeus dark brown. Mesonotum yellowish brown on anterior 2/3, brown on posterior 1/3, with 3 brown longitudinal stripe: unapparent and diffuse medially and thin laterally in some paratypes (Fig. 4 A), sometimes without any stripes in some paratypes. Postpronotal lobe brownish. Acrostichal setulae in ca. 14–16 irregular rows (Fig. 4 A). Scutellum brown, pale at tip (Fig. 4 A). Katepisternum brownish yellow (Fig. 4 B). Meron slightly brown (Fig. 4 B). Wing (Fig. 2 A): Costal vein between R2+3 and R4+5 distally with ca. 7 peg-like spinules on ventral surface. Halter slightly brown apically (Fig. 4 B). Legs slightly brownish on hind femur. Abdominal tergites brown to black (Fig. 8 A); second slightly yellow anteromedially, with 1 yellow patch laterally; third with a pair of narrow, yellow patches submedially along margin; fourth and fifth each with a pair of small, unconspicuous, yellow patches submedially along margin; sixth with yellow, M-shaped patch posteriorly. Male terminalia: Epandrium with ca. 7 setae near posterior margin and ca. 4 setae on ventral corner per side (Fig. 14 B). Hypandrium lacking sensilla (Fig. 14 C).
