Two New Synonyms of Paraleuctra orientalis (Chu, 1928) (Plecoptera: Leuctridae) Based on Morphological and Molecular Data, with Notes on Paraleuctra cervicornis Du and Qian, 2012

SIMPLE SUMMARY: Paraleuctra Hanson, 1941, is a widespread genus distributed in the east and west Nearctic and in much of the Palaearctic, with 27 valid species currently known. In China, although six Paraleuctra species have been reported, the differences among these species have not been fully explained. After checking a large number of specimens of this genus from Zhejiang Province, two junior synonyms are proposed for the species Paraleuctra orientalis (Chu, 1928). ABSTRACT: We recently examined specimens of the genus Paraleuctra Hanson, 1941, from Zhejiang Province and Sichuan Province, China, and two new synonyms are established based on morphological and molecular data. Paraleuctra sinica Yang and Yang, 1995, and Paraleuctra tianmushana Li and Yang, 2010, are synonymized with Paraleuctra orientalis (Chu, 1928). Additionally, we provide new images of Paraleuctra cervicornis Du and Qian, 2012, to facilitate identification of this species.
