Figs 9–12

Type material. Holotype male, CHINA: Hunan Province (lacking detailed collection data), 2 March 1975, Qiliang Huang leg. ( IZCAS).

Etymology. The species name is derived from the from past participle expansus , -a, -um of the Latin verb expandere, means “expanded” and refers to the expanded conductor, median apophysis and the distal end of embolus; adjective.

Diagnosis. This species can be easily distinguished from all other Draconarius by the extraordinarily expanded median apophysis.

Description. Holotype male. Prosoma 3.0 long, 2.1 wide; opisthosoma absent. Eye measurements: AME 0.08; ALE 0.15; PME 0.15; PLE 0.15; AME–AME 0.04; AME–ALE 0.05; PME–PME 0.10; PME–PLE 0.10; clypeus 0.10. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 9 ). Leg formula unknown; measurements of legs: I: 8.4 (2.4, 2.8, 2.0, 1.2); II: absent; III: absent; IV: 9.8 (2.6, 3.0, 2.9, 1.3).

Patellar apophysis short and stour; RTA broad, with distal end extending beyond tibia; lateral tibial apophysis absent; cymbial furrow extremely short; conductor broad, slightly modified into a shallow groove holding the embolus; dorsal apophysis of conductor sharp, and hidden by median apophysis from prolateral view; median apophysis extraordinarily expanded, and with distal margin thickened; embolus short, arising at approximately 4.30–o’clock–position, and with the distal end slightly modified into a shallow groove ( Figs 10–12 ).
