Svatactesis gen. nov., a new genus for Polyctesis johanidesi with notes on the tribe Polyctesini (Coleoptera: Buprestidae: Polycestinae)
Mark G. Volkovitsh
Svatactesis gen. nov. is established for Polyctesis johanidesi Bílý, 1997 known from Turkey and Iran, and compared with closely related genera Polyctesis Marseul, 1865, Bellamyina Bílý, 1994, and Schoutedeniastes Burgeon, 1941. Svatactesis johanidesi is re-described and illustrated. Composition, taxonomic state and relations of Polyctesini Cobos, 1955 and diagnostic characters of the genera belonging to the Polyctesis generic-group are discussed. The Schoutedeniastes magnifica (Waterhouse, 1875), S. amabilis (Laporte & Gory, 1835) and S. vitalisi (Bourgoin, 1922) species-groups are distinguished within the genus Schoutedeniastes. Evident variability of the main diagnostic characters among species-groups cast doubts on the monophyly of this genus. First exact record of Svatactesis johanidesi from Iran is provided.
