Dolichopus lineatocornis Zetterstedt 1843

Dolichopus lineatocornis Zetterstedt, 1843

MATERIAL EXAMINED. 1♂, Luzhsky district, Yashchera, 18.07.1970, A. Stackelberg leg.

DISTRIBUTION. Type locality: Sweden: Lund. Palaearctic: Belgium, Czech, Denmark, Estonia, Finland, Germany, Kazakhstan, Latvia, Lithuania, Netherlands, Russia (Krasnodar, Lipetsk, Mordovia, Pskov, Tatarstan, Tver, Voronezh, Yakutia), Sweden, UK. First record for the Leningrad Region.

NOTES. The species seems to be rare in collections. The junior author saw only few specimens collected from Mordovia, central Yakutia, Pskov Region (Velikie Luki) of Russia, and in northern Kazakhstan (near Nur-Sultan). Studying old literature, he noted a remarkable similarity of pictures of wing and hypopygium provided by Mik [1880] for single male of Dolichopus thalassinus Mik, 1880 (nec Haliday, 1832) and those in D. lineatocornis. Unfortunately, a short diagnosis for this male had no important diagnostic characters, e.g. slightly swollen hind tibia on basal half. Parent [1938] did not see Mik’s or new material, but gave a new name Dolichopus miki for D. thalassinus Mik (nec Haliday) and redrawn Mik’s pictures. Both Mik [1880] and Parent [1938] compared that male (from “ France ”) with Dolichopus simplex Meigen, 1824 having simple hind tibia and simple wing in male. We think that the slightly swollen hind tibia was overlooked by Mik, and that male of D. miki belongs to D. lineatocornis. As we know, nobody studied old or new material for D. miki. D. lineatocornis is yet unknown from France, but being reported from the neighboring countries and such warm region as Black Sea coast in the Krasnodar Territory.
