The Tipulidae s.l.-craneflies-are one of the largest groups of the Diptera containing over 15,270 valid species and subspecies.

Data on geographical and ecological distribution have been compiled lor the 95 species of crane flies found in two natural areas in northeastern Kansas, the Breidenthal Reserve and the Natural History Reservation of the University of Kansas. These distributions correlate well with various major plant communities, or with specific habitats. The ranges of several species are extended significantly westward. New records for species not previously recorded within 500 miles of Lawrence, Kansas, include: Nephrotoma alterna, Tipula (L.) perlongipes, Limonia (D.) haeretica, Dicranoptycha elsa, D. megaphallus, D. septemtrionis , Gonomyia (L.) manca, Ormosia arcuata, 0. in gloria, Tasiocera (D.) ursina and Molophilns pubipennis.

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.
