摘要
Species of the genus Dichopygina Vilkamaa, Hippa ＆ Komarova, 2004 has been morphologically cryptic. In this paper, eight species of the genus were clearly defined by DNA barcodes. Based on both molecular and morphological evidences, D. bernhardi Vilkamaa, Hippa ＆ Komarova, 2004, stat. rev. is separated from D. perfecta（Pettey, 1918）; a closely allied new species, D. tibetana Leng, Heller ＆ Huang, sp. nov., is described from Tibet, China. Detailed descriptions and figures of the two species are presented.
