ABSTRACT

Background: The family Nemouridae, belonging to Plecoptera, comprises 21 genera and over 700 species found globally, with the greatest diversity observed in temperate regions. Nemoura Latreille, 1796 and Amphinemura Ris, 1902 are two largest genera of the family with the highest diversity in China. New information Two new species of Nemoura Latreille, 1796 of the family Nemouridae, Nemouraexterclava Zhu, Rehman & Du sp. nov. and Nemouracerciserrata Zhu, Du & Rehman sp. nov., are described and illustrated from the Nanling Mountains Region in Guangdong Province, southern China. The morphological characteristics of the new species are compared with related taxa. Additionally, the status of Indonemouravoluta Li & Yang, 2008, originally from Maoershan National Natural Reserve in Guangxi Zhuang Autonomous Region, was addressed and moved to the genus Amphinemura Ris, 1902 on the basis of newly-caught topotypes.
