Small sized insects (1.0– 1.8 mm) with yellowish to almost black body, covered with short, erect, evenly distributed setae (usually females more pale and more densely setose than males). Head subglobular in dorsal and lateral views, subtriangular to globular in frontal view; eyes of female small, its largest diameter shorter than length of malar space; palpal formula 4–2. Male antenna 14 - merous with only A 4 to A 3 - A 4 modified; female antennae 12 - merous, with more or less abrupt 4 - merous clava to clava indistinct; A 1 about as long as four following antennomeres combined; A 4 - A 8 from subquadrate to transverse. Propleuron, mesopleuron ventrally, metapleuron, lateral side of propodeum and petiole covered with dense setation or foamy structures; mesoscutum transverse, without notauli, almost flat but slightly convex antero-medially and depressed postero-medially; mesoscutellum usually with single transverse anterior scutellar pit or it subdivided into two pits; propodeum with more or less distinct median carina that is not elevated anteriorly or carina absent; plica and posterior plical process slightly to moderately projecting. Alate, fore wing as long as body or slightly shorter, with single costal vein developed in its basal third. All legs with cylindrical tarsi, tarsomeres about as long as wide. Petiole in lateral view humped dorsally, elevated above level of base of T 2 and not broadened posteriorly; base of T 2 distinctly wider than petiole, smooth and flat; base of S 2 densely setose, with two groove-like invaginations laterally and median convexity between them; anterior margin of S 2 without deep excavation; gaster depressed and ovoid.
