Type material. Holotype male, CHINA: Sichuan, Lushan County (30.3° N, 103.0° E), Weita Village, near Shuiluodong Cave, 15 October 2005, Shuqiang Li leg. ( IZCAS)

Etymology. The species name is derived from the Latin acutus , -a -um, meaning “sharp” and referring to the sharply pointed distal tip of the conductor; adjective.

Diagnosis. This species is similar to Draconarius aspinatus (Wang, Yin, Peng & Xie 1990) in having the simple and sharply pointed conductor, but can be easily distinguished by the short cymbial furrow and short median apophysis, the narrow dorsal margin of conductor and the basally originating embolus.

Description. Holotype male. Total length 5.6, prosoma 2.9 long, 2.0 wide; opisthosoma 2.7 long, 1.6 wide. Eye measurements: AME 0.06; ALE 0.18; PME 0.15; PLE 0.15; AME–AME 0.06; AME–ALE 0.03; PME–PME 0.06; PME–PLE 0.10; clypeus 0.10. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 1 ). Legs with brown annulations; leg formula: IV, I, II, III; measurements of legs: I: 8.8 (2.4, 3.0, 2.0, 1.4); II: 7.7 (2.2, 2.5, 1.9, 1.1); III: 7.4 (2.1, 2.2, 2.0, 1.1); IV: 10.0 (2.8, 3.0, 2.9, 1.3). PLS with distal segment almost half length of basal one.

Patella with two small apophyses; RTA large, and with distal end distinctly extending beyond tibia; lateral tibial apophysis flat; cymbial furrow about half of cymbium length; tegulum strong; conductor simple, with a short and sharp distal end; dorsal apophysis of conductor large; median apophysis spoon–shaped; embolus moderately long, originating basally ( Figs 2–4 ).

Female. Unknown.

Distribution. China (Sichuan) ( Fig. 49 ).
