The western palaearctic species of Nephrotoma Meigen, 1803, (Diptera, Tipulidae) Part 1

Part 1 of this study deals with the western palaearctic species of the cornicina group (Savchenko, 1973b). For each taxon the references, type-material, material examined, description, biology and distribution are presented and discussed. Six taxa are new to science (lempkei, appendiculata pertenua, theowaldi, fontana, exastigma and sardegniensis), one is redefined (astigma) and one is given a new status (surcoufi). The females of beckeri, saccai, forcipata and schaeuffelei are described for the first time. Thirty-seven names are known in the literature for twenty-six taxa discussed.
