A new species of Teuchophorus (Dolichopodidae, diptera) from Morocco

Teuchophorus rifensis sp.n,. is a newly described species, collected at the border of the Talassemtane National Park in northern Morocco. This species can be distinguished from T. bipilosus and T. samraouii by the hind tibia with a slightly thickened apical half; hind tibia with a single fine bristle at 2/3, 3–3.5 times as long as diameter of tibia, and a row of 6–7 bristly hairs; hind tibia with a strong subapical ventral bristle and without ventral bristles in basal half. A key to determining the 14 Mediterranean species of Teuchophorus (males) is compiled.
