Wiedemannia (Philolutra) klausnitzeri Joost

(Fig. 7)

Wiedemannia (Philolutra) klausnitzeri Joost, 1981: 188 .

Diagnosis. This species differs by the completely dark brown scutum, acrostichals extending only to third dorsocentral seta, 5 pairs of dorsocentrals; lobes of clasping cercus orientated at right angles, L-shaped; digitiform lobe nearly directed vertically.

Distribution. Caucasus: Russia (Krasnodarskiy Territory).

Remarks. This species was described by Joost (1981), collected from the Sochi River (Russia, Krasnodarskiy Territory), but in the Catalogue of Palaearctic Diptera (1989) the species was mistakenly indicated from territory of Georgia [“Sotschi-Fluss, oberhalb des Ortes Plastunka (Georgian SSR)”]. Actually W. klausnitzeri is known only from type-locality: Krasnodarskiy Territory of Russia.

We were unsuccessful in collecting additional specimens of this species.
