Phylogenetic analysis of the genus Semioscopis (Lepidoptera, Depressariidae), with description of a new species from China

This study describes <i>Semioscopis sinicella</i> Wang, Zhu & Xiao, <b>sp. nov.</b> of the genus <i>Semioscopis</i> Hübner, 1825 (Lepidoptera, Depressariidae) from China. The new species is similar in external morphology and male genitalia to the European <i>S. avellanella</i> (Hübner, 1793) and the Japanese <i>S. similis</i> Saito, 1989, but it can be distinguished in female genitalia mainly by the distinctly shorter sclerotised section of the ductus bursae and the length ratios of the ductus bursae and corpus bursae to the papillae anales. Morphological descriptions and illustrations of the new species are provided. Furthermore, a phylogenetic analysis based on COI gene sequences using IQ-tree supports <i>S. sinicella</i> sp. nov. as a monophyletic lineage and further divides the genus <i>Semioscopis</i> into seven species groups.
