Type material. Holotype male, 6 female paratypes, CHINA: Sichuan Province, Mianning County (29.6° N, 102.0° E), Yele Nature Reserve, 24 July 2004, Xiang Xu leg.; 6 male and 3 female paratypes, same locality as for holotype, 21 October 2005, Xiufeng Zhang and Xiang Xu leg. ( IZCAS)

Etymology. The species name is a compound word from the Greek prefix pseudo– and the specific name of Draconarius coreanus (Paik & Yaginuma 1969) , pointing to the similarities in epigyna and male pedipalpi of both species; to be interpreted as a noun in apposition.

Diagnosis. This species is similar to D. coreanus in having short epigynal teeth, a shallow atrium, spiraled spermathecae in females, and having a broad conductor lamella, a long embolus, and a long cymbial furrow in males, but can be distinguished by the long, posteriorly originated spermathecal heads in females, and by the conductor with two sharp apexes in males.

Description. Holotype male. Total length 10.8, prosoma 5.8 long, 3.8 wide; opisthosoma 5.0 long, 3.3 wide. Eye measurements: AME 0.15; ALE 0.20; PME 0.20; PLE 0.25; AME–AME 0.13; AME–ALE 0.10; PME–PME 0.10; PME–PLE 0.26; clypeus 0.15. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 18 ). Leg formula: IV, I, II, III; measurements of legs: I: 14.8 (3.8, 5.2, 3.7, 2.1); II: 12.9 (3.4, 4.5, 3.0, 2.0); III: 11.4 (3.2, 3.9, 2.8, 1.5); IV: 15.1 (4.1, 5.0, 4.1, 1.9). PLS with distal segment almost equal to length of basal one.

Patellar apophysis long, slender; RTA with distal end not extending beyond tibia in retrolateral view; lateral tibial apophysis present; cymbial furrow slightly less than cymbium length; conductor lamella broad; conductor with two sharp apices; dorsal apophysis of conductor stout; median apophysis rounded; embolus extremely long, arising at approximately 5.30 to 6–o’clock–position ( Figs 19–21 ).

Female paratype. Total length 8.7. Prosoma 4.1 long, 2.7 wide; opisthosoma 4.6 long, 3.2 wide. Eye measurements: AME 0.13; ALE 0.25; PME 0.20; PLE 0.20; AME–AME 0.11; AME–ALE 0.10; PME–PME 0.10; PME–PLE 0.20; clypeus 0.18. Chelicerae with 3 promarginal and 2 retromarginal teeth. Leg IV formula: IV, I, II, III; measurements of legs: I: 10.3 (3.0, 3.5, 2.4, 1.4); II: 9.1 (2.7, 3.0, 2.1, 1.3); III: 7.5 (2.3, 2.2, 2.0, 1.0); IV: 10.5 (3.0, 3.4, 2.8, 1.3).

Epigynal teeth short, widely separated; atrium shallow, with the anterior margin extended medially; a shallow median concavity situated near to epigastric furrow; copulatory ducts indistinct; spermathecae separated posteriorly and overlapped anteriorly; spermathecal heads long, originating posteriorly ( Figs 22–23 ).

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