A new genus of the primitively segmented trapdoor spiders, which is endemic to the north of China, is described, Luthela gen. nov., and the status of Sinothela Haupt, 2003 and Sinothela sinensis (Bishop & Crosby, 1932) is discussed and both are treated as nomina dubia. The new genus Luthela gen. nov. is erected based on morphology and molecular data of the type species Luthela yiyuan sp. nov. A taxonomic revision of the new genus is given. Three Sinothela species are transferred to the new genus, L. luotianensis comb. nov. and L. schensiensis comb. nov. are redescribed using our newly collected specimens, include L. heyangensis comb. nov. as a junior synonym of L. schensiensis comb. nov., and describe six new species based on both male and female morphological characters: L. badong sp. nov., L. dengfeng sp. nov., L. handan sp. nov., L. taian sp. nov., L. yiyuan sp. nov., and L. yuncheng sp. nov.

Five Liphistius Schiödte, 1849 species of the primitively segmented spider family Liphistiidae are currently known from Myanmar. Here, we described a new species, Liphistius pyinoolwinsp. nov. (♂♀), which was collected from Pyin Oo Lwin, Mandalay Region, Myanmar, diagnosed based on its genital morphology. The specimens (2♂♂, 5♀♀) collected by Walter C. Sedgwick from Pyin Oo Lwin in 1982 were misidentified as L. birmanicus Thorell, 1897 and are treated here as the newly described species. Accordingly, we described the males of L. birmanicus for the first time, redescribed its female, using newly collected specimens from Yadò, Than Taung and Kalekho Atet townships, Kayin State. We also provided information on the variation in genital morphology of both species, and their relationships within the birmanicus-group of species.

We report three new species of the segmented trapdoor spider genus Qiongthela Xu & Kuntner, 2015 collected from Hainan Island, China based on morphological characters: Q. dongfang sp. nov. (♂♀), Q. nankai sp. nov. (♂♀), Q. yalin sp. nov. (♂♀). We also provide the GenBank accession codes of the DNA barcode gene, cytochrome c oxidase subunit I (COI), of the type specimens of all three new species to aid future identification.

The primitively segmented spider genus Qiongthela Xu & Kuntner, 2015 consists of seven species that are distributed in Hainan Island, China and southern Vietnam. Of the seven species, five are known from Hainan Island. In this study, four more Qiongthela species collected from Hainan Island are diagnosed and described as new to science based on morphological characters: Q. baotingsp. nov. (♂♀), Q. qiongzhongsp. nov. (♂♀), Q. sanyasp. nov. (♂♀), Q. yinggezuisp. nov. (♂♀). To facilitate future identification, the GenBank accession codes of the DNA barcode gene, cytochrome c oxidase subunit I (COI), for all the type specimens are also provided.

... Luthela Xu & Li, 2022, an endemic genus of northern China, was newly erected and delimited on the basis of morphological characters and molecular data, and it was transferred from Liphistiidae to Heptathelidae (Li 2022;Xu et al. 2022). At present, Luthela includes eight known extant species, which are distributed almost exclusively north of the Yangtze River to the Yellow river basin in China, but no species have been recorded in Beijing and Sichuan. ...
