Diagnosis. Hind margin of 10 th abdominal tergite with three large dark knobs. Male supra-anal plate with 2 + 2 large dark knobs. Lophi of epiphallus prominent, anterior portion and surrounding areas well sclerotized; sclerotized area semi-circular in dorsal view. Dorsal valves of aedeagus subtrapezoidal in dorsal view. Dorsal and ventral valves almost covered by the sheath of aedeagus.

Male redescription. External morphology ( Fig. 1A & C ). External genitalia ( Fig. 3A ). Cerci triangular with internal spine in the basal half. Margin of 10 th abdominal tergite thickened and forming three black projections. Supra-anal plate triangular with dilated margins. Four large and clear knobs in a 2 + 2 pattern. Internal genitalia ( Fig. 3B–E ). Epiphallus ( Fig. 3B & C ). Well sclerotized, bridge almost straight, anterior projections globose and rounded. Ancorae triangular. Lophi prominent with an anterior portion and surrounding areas well sclerotized. Semi-circular shape of this sclerotized area from dorsal view. Lateral plates poorly developed. Posterior projections enlarged. Oval sclerites semi-triangular. Ecto + Endophallus complex (fig 3D & E). Ectophallus. Apodemes of cingulum elongated with zygoma and ramus well-developed. Sheath of aedeagus complex and folded at tip. Endophallus. Apodemes of endophallus laterally compressed, arch of aedeagus elevated, “L shaped (in lateral view). Dorsal valvae well sclerotized, expanded laterally and subtrapezoidal in dorsal view with anterior outer margin concave and involving laterally ventral ones. Ventral valvae a little longer than dorsal ones, semicircular and with expanded rounded apex. Both valvae almost covered by sheath of aedeagus. Female description ( Fig. 1B & D ).
