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 <i>Pseudognaptorina</i>, with four described species, is endemic to the Qinghai-Xizang Plateau. In this study, <i>Pseudognaptorina</i> 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 <i>Pseudognaptorina</i> is presented. Six new species are described and illustrated: <i>P.banbarica</i> X.-M. Li, <b>sp. nov.</b>, <i>P.himalayana</i> X.-M. Li, <b>sp. nov.</b>, <i>P.migana</i> X.-M. Li, <b>sp. nov.</b>, <i>P.oblonga</i> X.-M. Li, <b>sp. nov.</b>, <i>P.rectangularis</i> X.-M. Li, <b>sp. nov.</b>, and <i>P.reni</i> X.-M. Li, <b>sp. nov.</b> This work provides valuable molecular, morphological, and distributional data for the study of species evolution in the subtribe Gnaptorinina.
