| Abstract: | In this paper, the Chinese species of the genus Belonuchus Nordmann, 1837 Nordmann, A. 1837. Symbolae ad monographiam staphylinorum. Ex Academiae Caesareae Scientiarum, Vol. 4, 1–167. Petropoli: Academiae Caesareae Scientiarum. Google Scholar] are revised. Four new species are described and illustrated: B. admirabilis sp. nov. from China (Beijing), B. applanatus sp. nov. from China (Yunnan), B. coomani sp. nov. from China (Yunnan and Guangxi) and Vietnam (Hoa-Binh) and B. obvelatus sp. nov. from Indonesia (Sumatra and Java). Belonuchus grandiceps (Kraatz, 1859 Kraatz, G. 1859. Die Staphylinen-Fauna von Ostindien, insbesondere der Insel Ceylan. Arch Naturgesch., 25: 1–196. Google Scholar]) and B. imitator Cameron, 1932 Cameron, M. 1932. “The Fauna of British India, including Ceylon and Burma. Coleoptera”. In Staphylinidae, Vol. III, 443London: Taylor & Francis. Google Scholar] are reported from China for the first time. Five existing Chinese species are re-described and illustrated: B. grandiceps, B. imitator, B. puncticulus, B. punctifrons and B. rufoniger. Belonuchus gardneri Cameron, 1932 Cameron, M. 1932. “The Fauna of British India, including Ceylon and Burma. Coleoptera”. In Staphylinidae, Vol. III, 443London: Taylor & Francis. Google Scholar] is placed in synonymy with B. rufoniger Fauvel, 1895 Fauvel, A. 1895. Staphylinides nouveaux de l'Inde et de la Malaisie. Rev Entomol., 14: 180–286. Google Scholar]. Consequently, eight species of the genus Belonuchus are now known from China. An identification key to the Chinese species of the genus Belonuchus is provided and their geographical distribution is mapped. |
