Prorachthes Loew View in CoL

Prorachthes Loew, 1869 a: 381 . Type species: Prorachthes ledereri Loew, 1868 , by monotypy.

Dumontiella Séguy, 1932: 126 . Type species: Dumontiella vespertilio Séguy, 1932 View in CoL , by original designation. Cheilohadrus Hesse, 1938: 674 . Type species: Cheilohadrus conspersipennis Hesse, 1938 View in CoL , by original designation.

Comments: The single southern African species, described as Cheilohadrus conspersipennis Hesse (1938) , differs from the palaearctic species in having a narrow, spindle-shaped flagellum rather than a broad flattened one. Otherwise, the genus is readily recognised by the mottled wings and dark vestiture. The spermathecae have small, ovoid bulbs and short ducts lacking sperm pumps.

Key: Palaearctic species, Engel (1932 –7), Paramonov (1940 b).

Distribution: Western Palaearctic and Southern Africa. North Africa: 3 species; Prorachthes crassipalpis Villeneuve (Algeria-Tunisia) , P. longirostris Bezzi ( Algeria, Egypt), P. vespertilio Séguy ( Tunisia) . Africa South of the Sahara: Eastern Cape, Namibia: 1 species; P. conspersipennis (Hesse) .
