Overcoming Linnean and Wallacean shortfall in a biodiversity hotspot—a taxonomic study of Tribasodites Jeannel and allied genera (Coleoptera: Staphylinidae: Pselaphinae) from Nanling Mountain Area, China

Abstract

This paper presents the result of a taxonomic study of the genus Tribasodites Jeannel and related genera (Staphylinidae: Pselaphinae: Batrisitae) from Nanling Mountain Area, with 55 species placed in 10 genera being recognized. Forty-one species are described as new, with illustrations of the habitus and diagnostic characters for reliable identifications: Anama angulata sp. nov., Anama horridula sp. nov., Anama reticulata sp. nov., Araneibatrus breviceps sp. nov., Araneibatrus gigas sp. nov., Araneibatrus leigong sp. nov., Araneibatrus maoermontis sp. nov., Batrisodes amphion sp. nov., Batrisodes breviventris sp. nov., Batrisodes capreolus sp. nov., Batrisodes latilobus sp. nov., Batrisodes microceps sp. nov., Batrisodes shun sp. nov., Batrisodes streptoaedeagus sp. nov., Batrisodes titanius sp. nov., Batrisodes tribasoditiformis sp. nov., Coryphomodes jiangxiensis sp. nov., Coryphomodes parvipunctatus sp. nov., Coryphomodes simplex sp. nov., Hypochraeus complanatus sp. nov., Hypochraeus robustus sp. nov., Intestinarius guangxiensis sp. nov., Intestinarius paralongiceps sp. nov., Tribasodites barbipes sp. nov., Tribasodites cavipes sp. nov., Tribasodites clavatus sp. nov., Tribasodites corniceps sp. nov., Tribasodites fortunatus sp. nov., Tribasodites furca sp. nov., Tribasodites jiulianmontis sp. nov., Tribasodites jiuwanmontis sp. nov., Tribasodites loki sp. nov., Tribasodites longipes sp. nov., Tribasodites mangshanensis sp. nov., Tribasodites paraspinatus sp. nov., Tribasodites pengi sp. nov., Tribasodites ruyuanensis sp. nov., Tribasodites spinatus sp. nov., Tribasodites turgipes sp. nov., Tribasodites xinningensis sp. nov., and Tribasodites yangi sp. nov. Tribasodites chinensis (Yin, Zhao & Li, 2010) comb. nov. is transferred from Tribasodes. Anama Newton & Chandler and Hypochraeus Raffray are newly recorded from China. New provincial records and additional collecting data are provided for Batrisodes bamian Yin, Shen & Li, Batrisodes grossus Jiang & Yin, Dendrolasiophilus wenhsini Yin & Li, Intestinarius guangdongensis Yin & Li, Intestinarius longiceps Yin & Li, Tribasodites chinensis, and Tribasodites hubeiensis Yin, Nomura & Li. Keys for identification of the genera and species are presented. A checklist of Batrisini from Nanling Mountain Area is provided, for a total of 64 species.
