Delimitation of the segmented trapdoor spider genus Luthela gen. nov., with comments on the genus Sinothela from northern China (Araneae, Mesothelae, Liphistiidae).

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.
