Abstract

<br> The riffle beetle genus<br> Zaitzevia<br> 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<br> Zaitzevia<br> species from China:<br> Z. fodingshanus<br> sp. nov.<br> from Guizhou Province and<br> Z. lipingae<br> sp. nov.<br> from Yunnan Province. Habitus and diagnostic features of the new species are illustrated, along with a checklist of all known Chinese<br> Zaitzevia<br> species, a key, and a distribution map of<br> Zaitzevia<br> 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 acrosslarger areas of Southwest China in the future.<br>
