Fourteen species of Tipula (Vestiplex Bezzi, 1924) crane flies (Diptera, Tipulidae) known from Mongolia are taxonomically revised. Identification keys for males and females, redescriptions and illustrations of all species are presented. Most genital structures are illustrated for the first time. Tipula (V.) jakut Alexander, 1934 is designated as junior synonym of T. (V.) sintenisi Lackschewitz, 1933; T. (V.) kamchatkana Alexander, 1934 is designated as junior synonym of T. (V.) mediovittata Mik, 1889. Tipula (V.) balioptera Loew, 1863 and T. (V.) leucoprocta Mik, 1889 are listed as new records for the Mongolian fauna.

Four new crane fly species of subgenus Tipula (Vestiplex) Bezzi, 1924, T. (V.) borthi sp. nov. (Sichuan, Qinghai and Gansu provinces, erectiloba species group), T. (V.) maoxianensis sp. nov. (Sichuan province, virgatula species group), T. (V.) xinduqiaoensis sp. nov. and T. (V.) auriculatalobata sp. nov. (Sichuan and Yunnan provinces, divisotergata species group) are described and illustrated. The newly described species can be separated using the identification keys provided for local species of the erectiloba, virgatula and divisotergata groups.

The Korean species of Tipula (Vestiplex) Bezzi, 1924 crane flies are taxonomically revised. Five species are recognized. Tipula (V.) coquillettiana Alexander, 1924, T. (V.) kuwayamai Alexander, 1921, T. (V.) tchukchi Alexander, 1934, and T. (V.) verecunda Alexander, 1924 are newly recorded from the Korean Peninsula, and T. (V.) serricauda Alexander, 1914 was previously recorded. The larva of T. (V.) serricauda is described and illustrated, and the larvae of the subgenus T. (Vestiplex) are divided into four groups based on spiracular lobe morphology. An identification key, redescriptions, and illustrations of Korean T. (Vestiplex) adults and grouping of known larvae are presented.

Two new species of the subgenus VestiplexBezzi, 1924 (genus Tipula Linnaeus, 1758), T. (V.) breviloba Men & Starkevich sp. nov. (Gansu province) and T. (V.) zhengkuni Men & Starkevich sp. nov. (Guizhou province) are described and illustrated. The taxonomy of the species groups of T. (V.) deserrata Alexander, 1934 and T. (V.) bicornigeraAlexander, 1938 is discussed. Tipula sexlobataAlexander, 1938 is placed within Vestiplex.

Two new crane fly species, Tipula (Vestiplex) gongdangensis sp. nov. and T. (V.) dechangensis sp. nov. are described and illustrated based on materials collected in the Yunnan and Sichuan provinces, China. A key is provided to distinguish males of the new species from those of other species in the T. (V.) immota Alexander, 1935 species group which is proposed here for the first time.
