Scutum and scutellum black, Notopleuron with 4 bristles. Scutellum with 4 bristles. Legs yellow brown. Front tibia lacking near-dorsal bristle and differentiated hairs, tarsomere 5 widened. Mid tibia with 2 longitudinal hair palisades, anterodorsal one straight and extending to 1/4(0.27) of tibia. Posterior face of hind trochanter with 4–5 bristles. Posterior face of hind femur with 5–6 stout bristles and several fine hairs along ventral margin. Ascending Process short, trapezoid, with 2 long and 1 short hairs apically. Hind tibia with 1 weak, anterodorsal bristle. Wing 1.64 mm long. Costal index 0.52. Costal ratios 4.6:1.24:1. Costal cilia 0.06 mm long. Vein M1 curved. Axillary ridge with 3 axillary bristles. All veins brown and membrane yellowish brown. Haltere brown. Abdomen. Tergites dark brown except tergite 1 and anterior half of tergite 2 pale yellow, with small hairs on tergites 1–5, but longer hairs on tergite 6 Venter light yellow. Hypopygium brown, boot-like.

Remarks. In the key to palaearctic species of Diplonevra ( Schmitz 1949) the new species runs to couplet 5 to D. florescens , it differed from latter by 1 anterodorsal bristle of hind tibia, a short, trapezoid ascending process of posterior face of hind femur.
