Type material. Holotype ♀ (IZCAS-Ar39616): Baiba Township (N29.79867º, E93.84720º, 3191 m), Bayi County, Nyingchi City, Tibet, China, 31. VII. 2012, Z.Y. Yao and Z. Zhao leg. GoogleMaps

Etymology. The specific name refers to the type locality, Baiba Township; adjective.

Diagnosis. Draconarius baibaensis sp. n. is most similar to D. altissimus ( Hu, 2001) . The epigyne of both species have a small atrium located posteriorly, and the epigynal teeth are pointed at the end, with spermathecal heads long and thin. However, the two species differ by the location of the epigynal teeth (medially in D. baibaensis sp. n. in Fig. 1A View FIGURE 1 and posteriorly in D. altissimus in fig. 43.1 in Hu 2001 and fig. 112A in Zhu et al. 2017) and the shape of the posterior margin of the atrium (rectangular in D. baibaensis sp. n. in Fig. 1A View FIGURE 1 and trapezoidal in D. altissimus in fig. 43.1 in Hu 2001 and fig. 112A in Zhu et al. 2017).

Description. Female (IZCAS-Ar39616). Cephalothorax brown. The clypeus, endites, labium darker than carapace but colour of sternum and legs the same as carapace. Abdomen light-brown, covered by gray hairs. The colour of spinnerets same as carapace. Total length 11.29. Carapace 5.20 long, 3.61 wide. Abdomen 6.09 long, 3.96 wide. Eye sizes and interdistances: AME 0.12, ALE 0.21, PME 0.15, PLE 0.18; AME–AME 0.12, AME–ALE 0.11, AME–PME 0.13, ALE–PLE 0, PME–PME 0.14, PME–PLE 0.04. Leg measurements: I 15.39 (4.84, 4.99, 3.36, 2.20); II 13.86 (4.18, 4.49, 3.21, 1.98); III 12.78 (3.91, 3.80, 3.16, 1.91); IV 16.74 (4.97, 5.04, 4.49, 2.24). Epigyne: subequal to 2 times wider than long with 2 triangular teeth, pointed at end, medially situated and widely separated, hoods distinct, atrium small and located posteriorly, posterior margin of atrium 4 times wider than long; spermathecae 1.5 times longer than wide, anteriorly wider than posteriorly, spermathecal heads long and thin, originating medially from the spermathecae; the width of fertilization ducts subequal to its length ( Fig. 1 View FIGURE 1 A–B).
