The Tipuloid Dipterans (Diptera, Tipulidae, Limoniidae) from the Putorana Plateau, with a Description of Dactylolabis tschernovi sp. n.

摘要

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