摘要

新种Cephonodes sanshaensis Deng & Huang被描述自中国三沙市附近的西沙群岛。提供了成虫及其生殖器的照片。hylas (Linnaeus, 1771) 和 C. picus (Cramer, 1777) 相似，但很容易通过雄性生殖器的特征加以区分：鳞茎的右叶呈钩状，先端明显锐尖，左瓣狭长，先端截形，右瓣宽大，呈刀状。基于细胞色素 c 氧化酶 I 基因条形码序列的分子分析被用来推断该新种在 Cephonodes 属中的系统发育位置。此外，还提供了 Cephonodes 属全球物种的最新检索表和核对表。

The genus Cephonodes from Xisha islands, Hainan Province, China, with description of a new species Cephonodes sanshaensis Deng & Huang, 2023 sp. nov. (Lepidoptera: Sphingidae)

A new species, Cephonodes sanshaensis Deng & Huang, sp. nov. is described from Xisha islands near Sansha City, China. Photographs of the adults and their genitalia are provided. The new species is similar to C. hylas (Linnaeus, 1771) and C. picus (Cramer, 1777) but can be easily distinguished by characters in the male genitalia: the right lobe of the uncus is hook-shaped with distinctly acute apex, the left valva is long and narrow with a truncate apex, and the right valva is broad and knife-shaped. Molecular analysis based on cytochrome c oxidase I gene barcode sequences is used to infer the phylogenetic position of the new species within the genus Cephonodes. An updated key and checklist to the worldwide species of the genus Cephonodes are also provided.
