Female: Body length 5.5–6 mm. The upper half of head black, except for a large spot on each temple lateral of the black postocellar area, the inner pale orbit broad; abdominal terigtes quite black above, or the median ones with very narrow marginal spot in the middle. All legs pale with narrow stripe from the trochanters downwards, on the hind ones also on coxa and a broad but short stripe also along the inner side of femur, apex of metatibia and most of metatarsus black. Wings hyaline, fore wing vein C and stigma pale green, other veins dark brown. Head shiny, on and around the frontal area with distinct microsculpture, thorax smooth. (In the Tibetan specimen, sculpture more distinct, and mesonotum with fine scattered punctures). Median fovea narrow and deep below, where it breaks through the rounded frontal ridges, above that becoming indistinct, but mostly reaching to the median ocellus; postocellar area convex, 2 times as broad as long; antenna as long as combined length of thorax and abdomen, flagellomere 1 slightly longer than flagellomere 2.

Male. Color and structures similar to female, otherwise: antenna as long as combined length of head and body, flagellomere 1 shorter than flagellomere 2, inner pale orbit narrow or wanting.
