Two new species of Nemouridae (Insecta: Plecoptera) from China

Abstract

Nemoura Latreille, 1796 and Amphinemura Ris, 1902 are the two largest genera of Nemouridae in China. In this paper, two new species are described and illustrated from China: Nemoura lixiana sp. nov. from Sichuan Province and Amphinemura jiaoheensis sp. nov. from Jilin Province. The two new species are diagnostic from congeners by the genitalic structures in males and females.

A new species of Nemoura (Plecoptera, Nemouridae) and supplementary description of Amphinemura cordiformis from the Nanling Mountains of southern China

“…The outer lobe of paraproct differ quite slightly in shape. Compared to some Chinese species, the male of N. biplatta appears similar to N. fusiformis Chen &Du, 2017 andN. nankinensis Wu, 1926 from Jiangsu province, particularly in respect of the oblong epiproct.…”

“…Both of these genera are comprised of approximately 200 valid species known from the Holarctic and Oriental regions (Baumann 1975;Yang et al 2015;Yang and Li 2018;DeWalt et al 2020). Currently, more than 40 species of the genus Nemoura and nearly 100 species of the genus Amphinemura have been recorded from China (Wu 1926(Wu , 1938(Wu , 1940(Wu , 1962(Wu , 1973Sivec 1981;Li and Yang 2005, 2006a, 2006b, 2007a, 2007b, 2008a, 2008b, 2008c, 2008d, 2011Wang et al 2006;Du et al , 2008; Wang and Du 2008;Li et al 2012;Li et al 2016Li et al , 2018aLi et al , 2018bChen andDu 2017a, 2017b;Mo et al 2017Mo et al , 2019Mo et al , 2020aMo et al , 2020bMo et al , 2020cQian et al 2018;Chen 2020).…”
