A revision of the spongillafly genus Sisyra Burmeister, 1839 (Neuroptera: Sisyridae) from China

Abstract

AbstractSisyra Burmeister, 1839 is cosmopolitan and the most specious genus of Sisyridae (spongillaflies). Hitherto, there has been only five species of Sisyra recorded from China. Here we present a taxonomic revision of the Chinese species of Sisyra. In total, six valid Sisyra species are reported from China. A new species, Sisyra bowlesi sp. n., is described from China, Laos and Vietnam. Sisyra indica Needham, 1909, S. nikkoana (Navás, 1910) and S. terminalis Curtis, 1854 are firstly recorded from China. Besides, two species from Hainan Island, S. hainana Yang and Gao, Citation2002 syn. n. and S. nervata Yang and Gao, Citation2002 syn. n., are herein synonymised with S. indica Needham, 1909; S. aurorae Navás, Citation1933 syn. n., recorded from eastern China, is synonymised with S. nikkoana (Navás, 1910) known from Japan, Korea and Russian Far East. New provincial records of S. curvata Yang and Gao, Citation2002 and S. yunana Yang, Citation1986 from China are added. A key to Sisyra species from Asia is provided.Keywords: Aquatic NeuropteraSisyridaeSisyrataxonomynew speciesnew synonymnew recordOriental RegionAsia AcknowledgementsWe are very grateful to all collectors who collected valuable specimens for the present study.
