Figs 43–49

Type material: Holotype female, 1 male paratype, CHINA: Hunan Province, Hengshan County (30.3°N, 102.8°E), Nanyue Mt., 6 October 2003, Xiang Xu leg. ( IZCAS)

Etymology. The species name zonalis , -is, -e is derived from the Latin noun zona, meaning “belt” and referring to the copulatory ducts resembling a waistbelt; adjective.

Diagnosis. This species is similar to D. neixiangensis (Hu, Wang & Wang, 1991) in having short epigynal teeth and missing a patellar apophysis, but can be distinguished by the presence of a strongly curved median apophysis, the embolus having a sharp distal end and the conductor exhibiting an apophysis on the distal margin in males ( Figs 44–46 ), and by the strongly sclerotised copulatory ducts and the strongly contorted spermathecae ( Fig. 48 ).

Description. Holotype male. Total length 4.6 (specimen dried), prosoma 3.0 long, 2.0 wide; opisthosoma 1.6 long, 1.0 wide. Eye measurements: AME 0.10; ALE 0.18; PME 0.15; PLE 0.15; AME–AME 0.03; AME– ALE 0.05; PME–PME 0.10; PME–PLE 0.13; clypeus 0.15. Chelicerae with 3 promarginal and 2 retromarginal teeth ( Fig. 43 ). Leg formula: IV, I, II, III; measurements of legs: I: 8.3 (2.3, 2.9, 2.0, 1.1); II: 7.5 (2.1, 2.5, 1.9, 1.0); III: 6.8 (1.9, 2.2, 1.8, 0.9); IV: 9.3 (2.5, 3.1, 2.6, 1.1). PLS with the distal segment slightly longer than the basal one.

Patellar apophysis absent; RTA sharp, with distal end extending beyond tibia; lateral tibial apophysis present; cymbial furrow short, about one fourth of cymbium length; conductor with apophysis on distal margin; dorsal apophysis of conductor large; median apophysis strongly curved distally; embolus moderately long, arising at approximately 7.30–o’clock–position ( Figs 44–46 ).

Female paratype. Total length 4.6 (specimen dried). Prosoma 2.8 long, 1.8 wide; opisthosoma 1.8 long, 1.5 wide. Eye measurements: AME 0.10; ALE 0.20; PME 0.20; PLE 0.20; AME–AME 0.03; AME–ALE 0.05; PME–PME 0.05; PME–PLE 0.15; clypeus 0.15. Chelicerae with 3 promarginal and 2 retromarginal teeth. Leg formula: IV, I, II, III; measurements of legs: I: 8.1 (2.1, 2.5, 1.7, 0.9); II: 6.3 (1.8, 2.2, 1.5, 0.8); III: 5.5 (1.5, 1.7, 1.6, 0.7); IV: 8.1 (2.1, 2.8, 2.3, 0.9).

Epigynal teeth small, situated on the anterior epigynum and widely separated from the atrium; atrium strongly reduced and with posterior margin strongly sclerotised; copulatory ducts zonal, originating laterally; spermathecae complex, separated not far from each other ( Figs 47–48 ).

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