Collection: Pensoft Publishers

Keywords: China · Topics: Diptera species taxonomy and behavior, Fossil Insects in Amber, Hymenoptera taxonomy and phylogeny

Two new species of subgenus Tipula (Vestiplex) Bezzi, 1924, T. (V.) leigongshanensis Men & Young, sp. n. and T. (V.) 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, T. (V.) bicalcarata, T. (V.) coxitalis Alexander, 1935, and T. (V.) 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.
