A revision of the Osmylus hyalinatus species group (Neuroptera: Osmylidae), with description of seven new species

A species group of the lance lacewing genus Osmylus Latreille, 1802, ie the Osmylus hyalinatus species group, is herein proposed, including the species previously placed in Plethosmylus Kr & uuml;ger, 1913 (currently a junior synonym of Osmylus). Seven new species of this species group from China are described: Osmylus flaviantennatus Zheng, Li, Wang and Liu sp. n., O. gaoligongensis Zheng, Li, Wang and Liu sp. n., O. qinlinganus Li, Zheng, Wang and Liu sp. n., O. trituberatus Li, Zheng, Wang and Liu sp. n., O. verticalis Li, Zheng, Wang and Liu sp. n., O. wenii Zheng, Li, Wang and Liu sp. n., and O. xiaohongae Zheng, Li, Wang and Liu sp. n. Furthermore, we record O. decoratus in China for the first time. A molecular species delimitation based on DNA barcodes was performed to verify the morphological identification of the species of the O. hyalinatus species group. http://www.zoobank.org/urn:lsid:zoobank.org:pub:NomenclaturalActs/C441EE8D-8147-4D66-9650-2EBEC3ABBEC3
