Type material. Holotype ♀ (IZCAS-Ar29625): Yingbin Road (N27.98375º, E85.98287º, 2450 m), Zhangmu Township , Nyalam County, Shigatse, Tibet, China, 29. VII. 2014, Y.C. Li leg. Paratype: 1♀ (IZCAS-Ar39626): same data as holotype .

Etymology. The specific name refers to the type locality, Yingbin Road; adjective.

Diagnosis. Draconarius yingbinensis sp. n. is most similar to D. nanyuensis ( Peng & Yin, 1998) . The epigynal teeth of both species are located anteriorly, close together, bent at the end, and have the same length to width ratio; atrium small, close to the posterior margin of the epigyne; spermathecae spherical, spermathecal heads originating anteriorly from the spermathecae. The two species differ by the shape of the epigynal teeth at the end (blunt in D. yingbinensis sp. n. in Fig. 7A and pointed in D. nanyuensis in fig. 8 in Peng & Yin 1998); the shape of the atrium (rectangular in D. yingbinensis sp. n. in Fig. 7A and with a triangular septum with atrium on both sides of septum in D. nanyuensis in fig. 8 in Peng & Yin 1998).

Description. Female (IZCAS-Ar39625). Carapace, sternum, legs, abdomen and spinnerets brown; clypeus, endites and labium darker than carapace.Abdomen with five chevron-shaped patterns and covered by blueish-green hairs. Total length 6.34. Carapace 3.48 long, 2.23 wide. Abdomen 2.86 long, 2.01 wide. Eye sizes and interdistances: AME 0.11, ALE 0.20, PME 0.11, PLE 0.16; AME–AME 0.08, AME–ALE 0.06, AME–PME 0.14, ALE–PLE 0, PME–PME 0.12, PME–PLE 0.16. Leg measurements: I 8.03 (2.34, 2.66, 1.72, 1.31); II 7.11 (2.13, 2.25, 1.56, 1.17); III 6.72 (1.88, 2.03, 1.72, 1.09); IV 8.72 (2.38, 2.66, 2.38, 1.30). Epigyne: more than 1.5 times wider than long, epigynal teeth about 3 times wider than long, located anteriorly and close together, hoods distinct, atrium small, close to the posterior margin of the epigynue, about 2.5 times wider than long, epigyne 3 times wider than atrium, copulatory openings near the center of the atrium, posterior margin of atrium 3.5 times wider than long; spermathecae spherical, as long as wide, spermathecal heads originating anteriorly from the spermathecae, copulatory ducts wide; fertilization ducts 4 times longer than wide ( Fig. 7 A–B).

Male. Unknown.

Variation. Total length of females 6.34, 6.53 (n=2).

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