Body length 3.8 mm, fore wing length 3.4 mm and antenna length 4.8 mm.

Antenna with 33 [female] to 35 [male] flagellomeres. Terminal flagellomere slender and strongly acuminate. Median flagellomeres 2 x longer than wide. Occipital carina produced anteriorly near the middle, broadly obliterated medially, ventrally joining hypostomal carina. Mesopleuron coriaceous-rugulose anteriorly, aciculate posteriorly, precoxal sulcus moderately impressed and rugose anteriorly, speculum shiny but with distinct conchoidal sculpture. Midlongitudinal carina of propodeum almost complete, posteriorly narrowly separatedfrom semicircular carina. Fore wing vein 2-CU1 1.5 x 1-CU1. Apex of fore wing subbasal cell evenly setose. Fore wing vein 3-SR 2.2 x vein r. Fore wing vein 2-SR+M 1.1 x vein r. Fore wing vein SR1 1.95 x vein 3-SR. Hind wing vein M+CU 1.2 x 1-M. Hind wing subbasal cell evenly setose. Hind wing vein m-cu absent. Apex of hind tibia with well-developed comb of specialised, adpressed setae both medially and ventrally between spurs. Claws without conspicuous pecten. Basal lobes of 1 st tergite weakly produced, more or less rounded but more steeply so posteriorly. Midlongitudinal carina of 3 rd tergite distinct and virtually complete.
