ABSTRACT
The crane fly subgenus Tipula (Vestiplex) Bezzi, 1924 (Diptera, Tipulidae) of Taiwan is taxonomically reviewed, entailing the recognition of 18 species, with six of these species newly described, including T. (V.) diamondisp. nov., T. (V.) formosaesp. nov., T. (V.) gracilianasp. nov., T. (V.) pseudobiserrasp. nov., T. (V.) survilaisp. nov., and T. (V.) taiwanicasp. nov. Three species, T. biaciculifera Alexander, 1937, T. niitakensis Alexander, 1938, and T. pseudobiaciculifera Men, Xue and Wang, 2016, listed previously as members of the subgenus T. (Pterelachisus) Rondani, 1842, are now formally placed as member taxa within T. (Vestiplex). Tipula subnata Alexander, 1949 and T. (V.) longarmata Yang and Yang, 1999 are designated as junior synonyms of T. (V.) coxitalis Alexander, 1935; T. (V.) nokonis Alexander, 1935 is designated as a junior synonym of T. (V.) terebrata Edwards, 1921; and T. (V.) takahashiana Alexander, 1938 is designated as a junior synonym of T. (V.) bicornigera Alexander, 1938. Included in this taxonomic revision are a key to species, species diagnoses for all species, complete descriptions for newly described species, and illustrations of the male genitalia for all species, and for female terminalia when available. DNA barcode sequences for all Taiwanese species of T. (Vestiplex) are provided. Males are associated with conspecific females based on CO1 results and maximum likelihood trees resulting from the analyses are presented. The Taiwan fauna of Tipula (Vestiplex) is highly endemic with 16 of the 18 species restricted to the island. At the species group level, no groups are endemic to Taiwan and the groups show closest biogeographic relationships to the Qinghai-Tibetan Plateau.
ABSTRACT
A new cranefly, Tipula (Vestiplex) levisoni sp. nov., is described and illustrated based on males and females collected in India and Nepal. The illustrations of male and female genitalia for the most closely related regional species, T. (V.) tanycera Alexander, 1961 and T. (V.) mitchelli Edwards, 1927 are also provided. The female of T. (V.) mitchelli is described for the first time.

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.
ABSTRACT
Two new crane fly species, Tipula (Vestiplex) gongdangensissp. nov. and T. (V.) dechangensissp. 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.
ABSTRACT
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.

Tipula (Vestiplex) scandens Edwards, 1928 and Tipula (Vestiplex) subscripta Edwards, 1928 were both briefly described based on single specimens and lacked illustration in the original literature. In the present paper, these two species are redescribed with new illustrations of additional morphological features based on type and non-type specimens.
ABSTRACT
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.

A new crane fly, Tipula (Vestiplex) butvilaisp. nov., is described and illustrated based on new material collected in the Nu Jiang Valley of Yunnan Province, China. The hypopygium for the most closely related species, Tipula (Vestiplex) testata Alexander, 1935, is also illustrated. A key is provided to distinguish males of the new species from those of other species in the T. (V.) bicornigera Alexander, 1938 species group.
ABSTRACT
Two new species of subgenus Tipula (Vestiplex) Bezzi, 1924, Tipula (Vestiplex) leigongshanensis Men & Young, sp. n. and Tipula (Vestiplex) maoershanensis Men & Young, sp. n. are described and illustrated. Tipula (Vestiplex) bicalcarata Savchenko, 1965 is redescribed and illustrated based on additional morphological characters. Partial mitochondrial cytochrome oxidase subunit I (COI) sequences of these three species are provided. Pairwise genetic distances among two new species and related species, Tipula (Vestiplex) bicalcarata, Tipula (Vestiplex) coxitalis Alexander, 1935, and Tipula (Vestiplex) sternotuberculata Alexander, 1935 range from 0.028 to 0.091 using Kimura-2-parameter model. Diagnostic features of the sperm pump for taxonomic use are discussed.
ABSTRACT
Based on examination of type specimens a crane fly species Tipula (Vestiplex) hugueniniana Alexander, 1971 is proposed as junior synonym of Tipula (V.) wahlgrenana Alexander, 1968. The new synonymy is based on similarity of male genitalia.
