Dolichopus longitarsis Stannius, 1831 View in CoL

Dolichopus longitarsis Stannius, 1831: 124 View in CoL

Dolichopus kowarzianus Stackelberg, 1928: 268 View in CoL syn. nov.

Demasculinised males examined: Coll. JK — Finland, 3ɗ Obb: Tervola, Hirviaapa (73475:34184), 8.vii. 2006, J. Kahanpää, id jka06-01355, -65, -67.

Dolichopus kowarzianus View in CoL is closely related to D. longitarsis View in CoL and differs from it by the broad face, the absence of ventral hairs on hind femora and the lack of a well-developed pterostigma ( Stackelberg 1930). The hypopygium is rather small with small cerci. The type locality of D. kowarzianus View in CoL is Františkový Láznĕ in western Czech Republic ( Negrobov 1991, Olejníček 1997).

Three males matching the description of this species were collected from Tervola together with numerous males of D. longitarsis View in CoL . All three were found to be parasitised. The differential diagnosis given by Stackelberg involves only characters typical for nematode-induced demasculinised males. D. kowarzianus Stackelberg, 1928 View in CoL is here synonymised with D. longitarsis Stannius, 1831 View in CoL .
