Description (female holotype). Length 1.2 mm. Head with lower face smooth, clypeus with weak reticulation; frons with weak reticulation, antennal scrobes indistinct but with median part of frons sunk to fit the antennae, nonsunken parts close to eyes with scattered setae. Vertex with weak reticulation and with scattered setae. Propodeal callus with nine setae. Fore wing with speculum present and closed below and towards base of wing; costal cell with four setae close to antero-apical margin, and with a complete row, consisting of nine setae, on ventral surface. Gaster ovate with apex ±pointed.

Colour. Head and mesosoma dark brown, non-metallic. Antennae yellowish-brown with dorsal part of pedicel and flagellum darker. Legs with coxae pale brown, trochanters, femora, tibiae and tarsi yellowish-brown. Wings hyaline. Gaster dorsally pale brown, ventrally yellowish-brown, lateral parts of tergites dark brown.
