THE TIPULOID DIPTERANS (DIPTERA, TIPULIDAE, LIMONIIDAE) FROM THE PUTORANA PLATEAU, WITH A DESCRIPTION OF DACTYLOLABIS TSCHERNOVI SP N.

The first data are presented on tipuloid dipterans from the Putorana Plateau, Central Siberian Tableland: the crane-flies, Tipula(Arctotipula) oklandi Al., Tipula (Pterelachisus) tundrensis stackelbergiana Lack., Tipula (Vestiplex) arctica Curt. and Tipula (Yamatotupula) lionota Holm.; and the limoniids, Dactylolabis (Dactylolabis) novaezemblae (Al.) and Dactylolabis (Dactylolabis) tschernovi sp. n. A new species, D. (D.) tschernovi sp. n., is described and illustrated from adult males and females. The male of the new species is very similar to that in Dactylolabis (Dactylolabis) carbonaria Say. and Dactylolabis (Dactylolabis) satanas Say., but can be distinguished from the former by the presence of a distinct throat, by the coloration of the head, femur, tibia and abdominal segments, as well as by the spear-shaped interbase of the hypopygium, from the latter species by the fully developed wings and the absence of large spines at the base of the interbases.
