All available type material of Tipula stackelbergi Alexander, T. usuriensis Alexander and T. subpruinosa Mannheims were examined. Tipula (Yamatotipula) stackelbergi stat. rev. is elevated from a subspecies of T. (Y.) pruinosa Wiedemann to a valid species. Two new synonyms are proposed: Tipula usuriensis syn. n. proved to be a junior synonym of T. (Y.) pruinosa and T. subpruinosa syn. n. a junior synonym of T. (Y.) freyana Lackschewitz. Tipula (Y.) stackelbergi is redescribed, male and female terminalia of T. (Y.) pruinosa are illustrated and discussed. Female terminalia of T. (Y.) freyana are described and illustrated for the first time. A key to both sexes of T. (Y.) stackelbergi and T. (Y.) pruinosa, and a key to females of T. (Y.) chonsaniana, T. (Y.) freyana and T. (Y.) moesta are provided. Subspecies are not uncommon among crane flies, but their ranges and traits are poorly known. An interdisciplinary approach (genetics, ecology, taxonomy) is suggested if subspecific ranks are to be used in tipuloid systematics.
