Description: Body length 8 mm, wing 5 mm. Palpus dark brown. Clypeus dark brown, shiny and with pale microsetulae. First flagellomere black. Fronto-orbital plates and frontal vitta dark brown. Epicephalon black. Row of katepisternal setae brownish, some of them shiny gold. Fore leg dark brown. Mid and hind femora white at basal third and yellowish at the apical third. Fore tarsus dark brown with gold/whitish pubescence ventrally at base of tarsomere one. Oviscape black, apex yellowish. Epandrium dark yellow.

Head: Palpus broadened basally and gradually tapering to apex. Clypeus short, length less than half of width. Frontal vitta with a narrowed depression centrally, reaching ocellar triangle. Two frontal setae. Vertex flattened. Paracephalon smooth, without swelling (not extending beyond the vertex). Inner vertical seta insertion flat, without tubercle. Line of black supracervical setae absent.

Thorax: Mesonotum with golden pruinosity. Scutellum upturned, triangular. Femora with sparse black setulae. Mid and hind tibia flattened, but sulcus on outer face weak. Wing with stigmatal and discal bands, apex clear with a dark and narrow preapical pigmentation. Crossvein r-m with small dark spot. R4+5 and M1+2 meeting at the wing margin. A1+CuA2 as long as CuA2. Female cervical sclerite smooth, without swelling.

Abdomen: T1–T4 with sparse brownish setulae. T5 and T6 with pale setulae. Female abdomen: Oviscape with pale and dispersed microsetulae. Single spermathecal duct (slightly damaged in Fig. 21 View FIGURES 20–23 ) apically broad, ending in a cylindrical but slightly irregular peanut-like spermatheca. Paired spermathecal duct smooth, slightly tapered on basal half. Paired spermathecal duct stems convoluted, with only small lobes. Paired spermathecae cylindrical, striate and goblet-like, deeply invaginated from apex to base. Male abdomen: Ejaculatory apodeme bigger than epandrium and with a broad blade, wider than sperm pump. Phallapodeme short, not extending to anterior limit of hypandrium. Distiphallus long, longer than epandrium, ending in a cylindrical phallic bulb about three times as long as wide ( Fig. 23 View FIGURES 20–23 ).
