Four New Species of the Genus Eoneureclipsis (Trichoptera: Psychomyiidae) from China Inferred from Morphology and DNA Barcodes

SIMPLE SUMMARY: The family Psychomyiidae Walker, 1852 currently includes 8 genera and more than 600 extant species, and is represented by three subfamilies, Psychomyiinae, Tinodinae, and Eoneureclipsinae. Subfamily Eoneureclipsinae was established by Mey in 2013, with the genus Eoneureclipsis Kimmins, 1955, based on morphological features, which were significant enough to separate it from the other genera of family Psychomyiidae. The new species in this study provide additional distribution data to the genus. ABSTRACT: Four new species of the genus Eoneureclipsis Kimmins, 1955 from China are described, illustrated, and diagnosed based on male genitalia: Eoneureclipsis jianfenglingensis sp. nov. from Hainan, E. foraminulatus sp. nov. from Guangxi, E. spinosus sp. nov. from Guangxi and Guangdong, and E. gei sp. nov. from Fujian. A dichotomous key to Chinese adult males of Eoneureclipsis is provided. A distribution map for all Eoneureclipsis species is also presented. The DNA barcodes (partial mtCOI sequences) of E. jianfenglingensis sp. nov., E. gei sp. nov., and E. hainanensis Mey, 2013 have been generated and compared with all existing sequences of Eoneureclipsis species.
