Figs 34–37 , 49

Type material: Holotype male, CHINA: Anhui, Huangshan Mt., Huangshan City (30.1°N, 118.1°E), 18 October 1990, Yinfang Chen leg. ( IZCAS)

Etymology. The species name is a participle of the Latin verb tendere, meaning “stretched” and referring to the stretched cymbium; adjective.

Diagnosis. This species is similar to D. expansus spec. nov. in having a broad conductor and a short embolus, but can be distinguished by the simple median apophysis and the hooked dorsal apophysis of conductor.

Description. Holotype male. Total length 7.4, prosoma 3.7 long, 2.7 wide; opisthosoma 3.7 long, 2.3 wide. Eye measurements: AME 0.18; ALE 0.20; PME 0.20; PLE 0.20; AME–AME 0.10; AME–ALE 0.05; PME–PME 0.10; PME–PLE 0.18; clypeus 0.18. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 34 ). Leg formula: IV, I, II, III; measurements of legs: I: 15.2 (3.9, 5.2, 4.0, 2.1); II: 14.1 (3.8, 4.7, 3.7, 1.9); III: 12.9 (3.4, 4.1, 3.7, 1.7); IV: 16.4 (4.2, 5.1, 5.1, 2.0). PLS with the distal segment distinctly shorter than the basal one.

Patellar apophysis stout; RTA long, with distal end slightly extending beyond tibia; lateral tibial apophysis absent; cymbial furrow about one third of cymbium length; conductor simple, modified into a deep groove hiding the distal end of embolus; dorsal apophysis of conductor hooked; median apophysis longer than wide; embolus short, arising at approximately 8.30–o’clock–position ( Figs 35–37 ).

Female. Unknown.

Distribution. China (Anhui) ( Fig. 49 ).
