Figs 5–8 , 49

Type material. Holotype male, CHINA: Hunan, Liuyang County (28.1° N, 113.6° E), Dawei Mt., near Yuquan Lake, 6 October 2003, Xiang Xu leg. ( IZCAS)

Etymology. The species name is derived from the Latin complanatus , -a, -um, meaning “flattened” and referring to the broad, flat conductor; adjective.

Diagnosis. This species can be distinguished from all other Draconarius by the broad and flat conductor, the broad embolus arising at approximately 7–o’clock–position, and the absence of a patellar apophysis.

Description. Holotype male. Total length 10.5, prosoma 5.1 long, 3.6 wide; opisthosoma 5.4 long, 3.1 wide. Eye measurements: AME 0.14; ALE 0.20; PME 0.18; PLE 0.20; AME–AME 0.10; AME–ALE 0.05; PME–PME 0.09; PME–PLE 0.22; clypeus 0.20. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 5 ). Leg formula: IV, I, II, III; measurements of legs: I: 15.0 (4.1, 5.2, 3.6, 2.1); II: 13.3 (3.7, 4.3, 3.3, 2.0); III: 10.4 (1.4, 3.8, 3.3, 1.9); IV: 16.1 (4.2, 5.2, 4.6, 2.1). PLS with the distal segment slightly longer than the basal one.

Patellar apophysis absent; RTA about half length of tibia, and with distal end extending beyond tibia; lateral tibial apophysis large; cymbial furrow about half of cymbium length; conductor broad, slightly curved basal, and with horned dorsal apophysis; median apophysis triangular in retrolateral view; embolus broad, almost equably wide from base to end, arising at approximately 7–o’clock–position ( Figs 6–8 ).

Female. Unknown.

Distribution. China (Hunan) ( Fig. 49 ).
