Contribution to the systematics of the subgenus Tipula (Schummelia) (Diptera: Tipulidae), with the description of a new species from South Korea

The article contains the expanded and clarified diagnoses of the subgenus Schummelia Edwards, 1931 of the genus Tipula Linnaeus, 1758 (Diptera: Tipulidae) and the type species of Schummelia, T. (Sch.) variicornis Schummel, 1833, which includes two subspecies. The diagnostic characters distinguishing Schummelia from the closely related subgenus Platytipula Matsumura, 1916 are discussed. The external and internal structures of the male terminalia of T. (Sch.) variicornis variicornis and T. (P.) insulicola fuscicauda Alexander, 1924 are illustrated and discussed. A new species of Schummelia from South Korea, T. (Sch.) baei sp. nov., is described and illustrated. Two species, Tipula (Sch.) crastina Alexander, 1941 and T. (Sch.) quiris Alexander, 1940, are transferred from Schummelia to Platytipula. The identification keys to males and females of Schummelia species of the Palaearctic Region are provided.
