Forcipomyia (Lasiohelea) sibirica (Diptera, Ceratopogonidae) w Polsce

A single male of Forcipomyia (Lasiohelea) sibirica (Bujanova, 1962) was collected in the Pieniny Mts. This is the first record of the species from Poland. F. sibirica is an Eastern Palaearctic bloodsucker causing a severe annoyance to humans in the vicinities of Krasnoyarsk (East Siberia). It seems that in Central Europe the species lives only in mountains which probably are its relict refuges since the Pleistocene. F. sibirica is very similar to F. nipponica. The only difference is found in the relation between X and XI male flagellomeres. In F. Nipponica flagellomere X is shorter than the next one, while in F. sibirica they are inversely related.
