title: Two new species of the genus Nephrotoma (Diptera, Tipuloidea, Tipulidae) from China with a key to species from Mainland China.
abstract: Nephrotoma liankangensis sp. n. and Nephrotoma pseudoliankangensis sp. n. are described from males and females collected from Henan and Yunnan provinces, China. Morphological descriptions and illustrations for the new species are provided. A key to known species from mainland China is provided. Some internal reproductive structures, including male semen pump, female vaginal apodeme and spermatheca, are described and compared. The possible usefulness of these internal reproductive structures for separating related species is analyzed. The type specimens are deposited in the animal specimen room, School of Life Sciences, Anqing Normal University, Anhui Province, China.
