Material examined.

2♂♂, India, West Bengal, Darjeeling , (27°2'51"N, 88°16'6.96"E), Light trap, 09.XI.2021, Col. G. S. Pal.

Diagnosis.

Male. Wing densely covered with microtrichia. Aedeagus shield shaped and tip of the aedeagus with small pointed projection. Parameres fused basally and strongly constricted, lateral process well developed and elongated.

Male (n = 2).

Supplementary description.

Head dark brown. Eyes contiguous. Length ratio of flagellomeres (I-XIII): 36-38: 22-23: 22: 22: 21: 20-21: 21: 21: 21-22: 68-71: 45-47: 35-36: 47-50; AR 1.18. Length of palpal segments: 10-11: 18-20: 33-36: 21-22: 15-16; PR 3.27-3.30. Wing large with dense microtrichia, WL 1.77-1.81, WW 0.50-0.52, CR 0.44-0.45. TRI 0.83-0.86, TRII 0.57-0.59 and TRIII 0.66-0.68. Gonocoxite almost 2.5 times longer than its greatest width (142.5 × 57.5); gonostylus 0.7 times shorter than gonocoxite. Aedeagus (Fig. 3 ) triangular, shield shaped with pointed projection at tip.

Discussion.

Wing length of both African and Chinese specimens is much greater than the Indian counterpart, but the wing width is almost the same, and value of AR and TRIII is greater than those of Indian species.

Female, Pupa and Larva. Unknown.

Distribution.

Burkina Faso, South Africa, China and India (new record).

subgenus Forcipomyia Euprojoannisia Brèthes, 1914
