Diagnosis. Wing with only 2 medial veins. Pedicel as long as scape. Vein M 1+2 twice as longer as r-m.
Description. Head. Scape ca. 1.3 times longer than wide. Pedicel similar to scape in length (autapomorphic feature). Pedicel as long as first flagellomere. Penultimate flagellomere ca. 1.1 times longer than last one ( Fig. 5a View FIGURE 5 ).
Thorax. Thoracic sclerites shown in Fig. 6a View FIGURE 6 . Wing shown in Fig. 1a View FIGURE 1 , Fig. 3a View FIGURE 3 , and Fig. 7a View FIGURE 7 . Vein Sc ending at level of R 2+3. Vein R 2 3 times longer than vein R 2+3. Length of vein R 2+3+4 2.3 times longer than vein R 2+3. First section of vein R 5 1.9 times longer than cross-vein r-m. First section of vein M 1+2 3.2 times longer than cross-vein r-m. Two medial veins present. Distance between M 1+2 and R 5 smaller than distance between M 3+4 and M 1+2.
Female terminalia. Female tergite X 1.6 times longer than wide. Dorsal margin of tergite X with a projection. Cercus tilted up, 1.8 times smaller than length of tergite X. Ventral margin of tergite IX 2.7 times longer than dorsal margin. Dorsal projection of sternite IX angulated. Posterior projection of sternite IX zigzagged. Hypogynial valves almost circular, 1.1 times longer than wide and less wide than sternite IX ( Fig. 8a View FIGURE 8 ).
Male terminalia. Male terminalia illustrated in Fig. 9a View FIGURE 9 (Details of chaetotaxy shown in Fig 10a View FIGURE 10 ). Gonocoxite 1.6 times longer than lobe of gonostylus and 1.4 times longer than clasper of gonostylus. Parameres with concave anterior margin. Sheath of aedeagus with bifid projection with very small tips. Bridge between interbases as wide as aedeagus. Long tip of the bifid posterior projection of interbases four times longer than the short tip. Both projections of dorsal interbase pointing to the right.
Coloration. General coloration brown. Head: brown with few dark punctures. Rostrum brown, palpi brown. Antennae yellowish brown with outer segments light brown.
