Systematic review of the genus Pseudognaptorina Kaszab, 1977 (Coleoptera, Tenebrionidae, Blaptinae, Blaptini) from the Qinghai-Xizang Plateau, with description of six new species

The genus Pseudognaptorina, with four described species, is endemic to the Qinghai-Xizang Plateau. In this study, Pseudognaptorina is reviewed based on a combination of molecular and morphological datasets. A preliminary phylogenetic tree is reconstructed based on COI sequences of four related genera within the subtribe Gnaptorinina.

Additionally, the geographical distribution of Pseudognaptorina is presented. Six new species are described and illustrated: P. banbarica X.-M. Li, sp. nov., P. himalayana X.-M. Li, sp. nov., P. migana X.-M. Li, sp. nov., P. oblonga X.-M. Li, sp. nov., P. rectangularis X.-M. Li, sp. nov., and P. reni X.-M. Li, sp. nov. This work provides valuable molecular, morphological, and distributional data for the study of species evolution in the subtribe Gnaptorinina.
