Front tibia with a dorsal bristle two fifths of length from base and with 8–10 small differentiated hairs extending below this to the tip. Mid tibia with 2 longitudinal hair palisades, anterodorsal one sharply deflected onto anterior face and extending to 2/3 (0.68) of tibia. Posterior face of hind trochanter with 3 bristles laterally. The base of hind femur extending rewards and forming a horn-like tip which bearing 3 bristles closed each other, lacking ascending process.

Axillary ridge with 4 axillary bristles. All veins brown and membrane yellowish brown. Haltere pale brown. Abdomen.

Remarks. In the key to palaearctic species of Diplonevra ( Schmitz 1949) the species runs to couplets 5 to D. florescens , but it can be easily distinguished by the horn-like base of hind femur.
