Draconarius exilis sp. nov. ( Figs. 1–7 View FIGURES 1 – 6 View FIGURE 7 )
Type material: Holotype male, 5 male and 20 female paratypes, from Jiuzhaigou (33°17’ N, 103°54’ E, 3000m), Sichuan, China, 20 September 2004, Z.S. Zhang leg., deposited in MHBU.
Etymology: The specific name is derived from “ exilis ” (Latin—thin, slender), referring to the thin and long male palp. It is an adjective in apposition.
Diagnosis: The male is similar to D. incertus ( Wang 2003: 535, figs. 35A–B), but can be distinguished by the absence of a patellar apophysis and the short RTA (only 1/3 tibial length). Females can be distinguished from both D. incertus ( Wang 2003: 541, figs. 47A– B) and D. pseudobrunneus ( Wang 2003: 544, figs. 52A–B) by the indistinct wrinkled epigynum and the variable shape of their spermathecae ( Figs. 2–6 View FIGURES 1 – 6 ).
Description: Male (holotype): Total length 8.06: carapace 4.08 long, 2.96 wide; abdomen 4.18 long, 2.45 wide. AME 0.20, ALE 0.18, PME 0.15, PLE 0.13. AME–AME 0.08, AME–ALE 0.05, PME–PME 0.15, PME–PLE 0.20. ALE–PLE 0.08. MOA 0.45 long, front width 0.33, back width 0.45. Clypeus height 0.23. Chelicerae with 3 promarginal and 2 retromarginal teeth. Leg formula: 4123.

Female (one of the paratypes): Total length 8.98: carapace 4.39 long, 2.96 wide; abdomen 4.89 long, 3.26 wide. AME 0.13, ALE 0.20, PME 0.15, PLE 0.20.

Leg measurements:
Epigyne ( Figs. 2–3 View FIGURES 1 – 6 ) weakly wrinkled, without epigynal teeth; atrium slitlike, indistinct; copulatory ducts short, mesally originating; spermathecae small, rounded, slightly anterior extending and widely separated by approximately their width; spermathecal heads anterior originating.
Habitat: Under the deadwoods or tree barks in humid locality.
Distribution: China (Sichuan) ( Fig. 7 View FIGURE 7 ).
