The assassin bug genus Epidaus Stål, 1859 (Hemiptera, Reduviidae, Harpactorinae) includes 28 species mainly distributed in the Oriental and Palaearctic Regions, with China being a major diversity hotspot, hosting nine known species. Epidaus nanlingensis Wang Z, Liu & Cai, sp. nov. from Nanling National Nature Reserve, Guangdong, China, is described and illustrated, based on both male and female specimens. A comparative study of the new species and its morphologically similar species is presented. An updated identification key to all ten Chinese species of the genus Epidaus is provided.
Wang et al. (2026) studied this question.
