Type material. Holotype ♀ (IZCAS-Ar39617): Budanla Mountain (N29.02890º, E92.35338º, 4930 m), Nyalam County, Shigatse, Tibet, China, 10. VIII. 2014, Y.C. Li leg.

Etymology. The specific name refers to the type locality, Budanla Mountain; adjective.

Diagnosis. Draconarius budanlaensis sp. n. is most similar to D. yadongensis ( Hu & Li, 1987) . The epigyne of both species has broad teeth that are widely separated; atrium flat and wide; spermathecae close together medially. The two species differ by the locations of the epigynal teeth (laterally in D. budanlaensis sp. n. in Fig. 2A and centrally in D. yadongensis in fig. 20.1 in Hu & Li 1987); the shape of the epigynal teeth (broad and short in D. budanlaensis sp. n. in Fig. 2A and as wide as long in D. yadongensis in fig. 20.1 in Hu & Li 1987), and the length of the posterior margin of the atrium (1/3 as long as wide in D. budanlaensis sp. n. in Fig. 2A and 5 times wider than long in D. yadongensis in fig. 20.1 in Hu & Li 1987).

Description. Female (IZCAS-Ar39617). Carapace and legs brown. Clypeus, endites, labium and sternum black-brown. Abdomen grey-brown. The colour of spinnerets equals the carapace. Abdomen with five chevronshaped patterns. Total length 14.10. Carapace 6.41 long, 4.16 wide. Abdomen 7.69 long, 3.95 wide. Eye sizes and interdistances: AME 0.16, ALE 0.20, PME 0.18, PLE 0.19; AME–AME 0.21, AME–ALE 0.17, AME–PME 0.22, ALE–PLE 0, PME–PME 0.29, PME–PLE 0.28. Leg measurements: I 16.79 (4.49, 5.77, 3.92, 2.61); II 15.69 (4.16, 5.13, 3.80, 2.60); III 15.54 (4.01, 4.81, 4.16, 2.56); IV 19.48 (4.80, 6.09, 5.38, 3.21). Epigyne: about 1.5 times wider than long, with 2 broad teeth that are about 3 times wider than long, situated anteriorly and widely separated, hoods distinct, atrium flat and wide, about 1.7 times wider than long, posterior margin of atrium 3 times wider than long; spermathecae longer than wide, spermathecal heads originating anteriorly from the spermathecae; fertilization ducts 3 times wider than long ( Fig. 2 A–B).

Male. Unknown.

Distribution. Known only from Tibet, China ( Fig. 8 ).
