Wing length 1.6–1.9mm (♂), 2.2mm (♀). Length of ultimate section of vein CuA 1 divided by penultimate section: 1.7–2.5. Eye height divided by gena height: 3.2–5.5. Scutum shining. Parafacial and orbital plate slightly projecting.

Chaetotaxy: Two ori, two ors. Acrostichal setulae in four rows.

Colouration: Calypter margin and hairs grey. Base colour of head varies from light yellow to light brown; back of head, ocellar tubercle, posterolateral corner of frons (encompassing base of both vertical bristles), clypeus, palpus and entire antenna dark brown; lateral margin of frons brown with stripe extending onto parafacial and sometimes encompassing base of fronto-orbitals; face brown; gena dirty to light yellow. Scutum dark with lateral margin yellow presuturally (brown spot on postpronotum relatively large) and region above wing base yellowish; laterotergites dark. Pleuron dark with posterodorsal margin of katepisternum yellowish. Legs dark brown with apex of fore femur sometimes yellowish and if so, then apex of mid and hind femora also sometimes yellowish. Abdomen dark brown.

Genitalia: Figs 37–40 View FIGURES 37–42 . Surstylus with single subapical spine. Paraphallus possibly homologous with one pair of transverse petal-shaped lobes that are fused medially to each other and distiphallus. Hypophallus prominent with long hairs along medial and apical margins. Mesophallus not evident. Distiphallus large, slightly tapering basally (seen ventrally), with one pair of thin elongate-oval apicoventral plates and one pair of small fringed structures in distal chamber. Ejaculatory apodeme with pileus ejaculatorius dark; stem nearly absent; base very broad and asymmetrical; blade large and dark, becoming paler apically excluding dark marginal stripe; base of duct dark.
