Revisiting the Oriental genus Syleter Andrewes, 1941 (Coleoptera: Carabidae: Clivinini)

Abstract

Abstract: The species group formerly included in the genus Syleter Andrewes, 1941 from the Oriental region is redefined resulting in the split of three genera, the original genus Syleter and two new genera, Parasyleter gen. nov. and Clypeuspinus gen. nov. Genus descriptions of the three genera and an identification key to the three genera is provided. Type species for the three genera are either re-established or designated and illustrations are provided for all of them. The genus Syleter is revised. The species Syleter acutipalpis (Putzeys) is resurrected to species status from synonymy with S. paradoxus (Putzeys). For S. acutipalpis a lectotype has been designated in order to maintain nomenclatural stability. The following new taxa are described: S. sinepunctatus sinepunctatus sp. nov., S. sinepunctatus kluangensis ssp. nov., and S. gradus sp. nov. A key to the Syleter species is provided. The genus Clypeuspinus gen. nov. is represented by one species, C. validus (Andrewes) comb. nov., which is redescribed.
