Two new species of Nemoura Latreille and a new combination of Amphinemura Ris (Plecoptera, Nemouridae) from the Nanling Mountains Region of China

Abstract

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. Two new species of Nemoura Latreille, 1796 of the family Nemouridae, Nemoura exterclava Zhu, Rehman & Du sp. nov. and Nemoura cerciserrata 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 Indonemoura voluta 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.
