Additional new species of the genus <i>Zaitzevia</i> (Coleoptera, Elmidae) from China with an updated key to species from mainland China.

ABSTRACT: The riffle beetle genus Zaitzevia Champion, 1923 comprises 29 described species, distributed across Asia and North America. China exhibits particularly high species diversity within this genus, with 16 recorded species. In this study, we describe two new Zaitzevia species from China: Z. fodingshanus sp. nov. from Guizhou Province and Z. lipingae sp. nov. from Yunnan Province. Habitus and diagnostic features of the new species are illustrated, along with a checklist of all known Chinese Zaitzevia species, a key, and a distribution map of Zaitzevia species from mainland China. The comparative diagnoses discuss characters of the new and known species. The results show that the existing species diversity requires more detailed research ac
