Figures 20 , 21 , 24 Type material. Holotype ♂ (SWUC-T-AM-16-01), CHINA , Hubei , Xuanen County , Changtanhe Township , Dawolong Village , 30°04.009′N 109°44.003′E , 774 m , 15.V.2018 , L.Y. Wang. Etymology. The specific name is derived from the type locality, adjective in apposition. Diagnosis. Males of this new species resemble T. yangi sp. nov. males by having a similar interior branch of the dorsal tibial apophysis and a similar embolus ( Figs 20A–C , 21B–D ). T. xuanenensis sp. nov. can be differentiated from T. yangi sp. nov. by the following: interior branch of dorsal tibial apophysis sharper in T. xuanenensis sp. nov. ( Figs 20A , 21B ) than in T. yangi sp. nov. , median apophysis crescent-shaped in T. xuanenensis sp. nov. ( Figs 20B, C , 21C, D ), whereas slender in T. yangi sp. nov. ; tegular apophysis heart-shaped in T. xuanenensis sp. nov. ( Figs 20A, B , 21B, C ), whereas D-shaped in T. yangi sp. nov. Description. Male. Holotype ( Fig. 21A ) total length 5.07. Carapace 2.64 long, 1.93 wide; opisthosoma 2.63 long, 1.62 wide. Eye size and interdistances: AME 0.13, ALE 0.18, PME 0.16, PLE 0.18; AME–AME 0.09, AME– ALE 0.10, PME–PME 0.17, PME–PLE 0.24, ALE–PLE 0.06. MOA 0.47 long, front width 0.33, base width 0.48. Clypeus height 0.17. Chelicerae with 4 promarginal and 3 retromarginal teeth. Leg measurements: I 13.04 (3.51, 4.61, 3.43, 1.49); II 8.95 (2.54, 2.95, 2.22, 1.24); III 7.10 (2.09, 2.22, 1.85, 0.94); IV 8.99 (2.53, 2.96, 2.44, 1.06). Male palp ( Figs 20 , 21B–D ). Palp with a small retrolateral tibial apophysis, located anteriorly on tibia. Interior branch of dorsal tibial apophysis needle-like, anteriorly pointed; exterior branch of dorsal tibial apophysis depressed in prolateral view, with an obvious pit. Median apophysis with a crescent-shaped base. Tegular apophysis heartshaped. Female unknown. Distribution. Known only from the type locality, Hubei , China ( Fig. 24 ).
