Morphology and DNA barcodes of two sympatric species of Filchneria Klapálek, 1908 (Plecoptera: Perlodidae): intraspecific variation and underestimated biodiversity of the genus

A new perlodid species of Filchneria Klapálek, 1908, Filchneria tianshana sp. n., from the middle section of Tianshan Mountains, Xinjiang Uygur Autonomous Region, China is described and illustrated based on males, females, and eggs. Another species, Filchneria sp. CH-1, is described based on females and eggs from the same location. DNA barcodes of the two species are sequenced and analysed, revealing intraspecific variation of F. tianshana sp. n. and delimitation of the second species.http://www.zoobank.org/urn:lsid:zoobank.org:pub:F6314C6A-BCB0-40B8-81B8-F703D56F40AA
