A New Species of the Buprestid Genus Cantonius Théry, 1929 (Coleoptera, Buprestidae) from China with Nomenclatural and Synonymic Notes on the Genera Cantonius and Cantoniellus Kalashian, 2004.

Cantonius (Procantonius) austrisinicussp. n. from Southern China (Guangxi Zhuang Autonomous Region and Guangdon Province) is described. Lectotypes of Cantonius obesus Obenberger 1940 and Aphanisticus cephalicus Kerremans, 1892 (Cantoniellus cephalicus (Kerremans, 1892)) are designated. A key to the species of the subgenus Procantonius Kalashian, 2004 is provided; it includes, in addition to C. (P.) obesus and the new species, C. (P.) khnzoriani Kalashian, 2004 and C. (P.) jendeki Kalashian, 2004. A new combination Cantoniellus laosensis (Baudon, 1968), comb. n. (from the genus Endelus Deyrolle, 1864) and a new synonymy C. laosensis (Baudon, 1968) = C. kubani Kalashian, 2004, syn. n. are established. [ABSTRACT FROM AUTHOR]
