Cozyptila haocongi Lin & Li , sp. nov. ( Figs 61–62 , 69C–D )

Etymology. The species is named after Mr. Haocong Yang; noun (name) in genitive case.

Diagnosis. Males of the new species can be distinguished from all congeners by having the ventral tibial apophysis strongly curved and the dorsal tibial apophysis lacking a hook. The female can be distinguished from all congeners by the long and curved copulatory ducts.

Description. Male (holotype). Total length 3.11; carapace 1.68 long, 1.51 wide, opisthosoma 1.43 long, 1.33 wide. Eye sizes and interdistances: AME 0.06, ALE 0.13, PME 0.05, PLE 0.09, AME–AME 0.20, AME–ALE 0.12, PME–PME 0.18, PME–PLE 0.29, AME–PME 0.19, ALE–PLE 0.19. Leg measurements: I 4.88 (1.45, 1.75, 0.93, 0.75), II 4.92 (1.50, 1.78, 0.98, 0.66), III 3.39 (1.10, 1.20, 0.56, 0.53), IV 3.41 (1.12, 1.19, 0.58, 0.52).

Coloration ( Fig. 69C ). Carapace dark brown, covered with clavate setae. Chelicerae, endites and labium yellow-brown. Sternum brown. Legs yellow-brown with brown irregular patterns. Opisthosoma pentagonal, yellow-brown, covered with clavate setae, with irregular black and white spots. Spinnerets yellow-brown.

Palp ( Fig. 61 ). Patella almost as long as tibia, with one dorsal macroseta. Tibia with three apophyses, ventral tibial apophysis club-shaped, terminus expanded, strongly curved, intermediate apophysis shorter than ventral one. Retrolateral tibial claw as long as ventral tibial apophysis, terminally expanded and flat. Tegulum flat, disk-shaped. Embolus coiled. Female (one paratype Ar43998). Total length 3.87; carapace 1.77 long, 1.66 wide, opisthosoma 2.10 long, 2.11 wide. Eye sizes and interdistances: AME 0.06, ALE 0.13, PME 0.05, PLE 0.10, AME–AME 0.23, AME–ALE 0.14, PME–PME 0.20, PME–PLE 0.33, AME–PME 0.23, ALE–PLE 0.21. Leg measurements: I 4.98 (1.47, 1.82, 0.96, 0.73), II 4.87 (1.53, 1.67, 0.93, 0.74), III 3.39 (1.10, 1.22, 0.53, 0.54), IV 3.40 (1.13, 1.12, 0.65, 0.50).

Coloration ( Fig. 69D ). Similar to that of male except paler.

Epigyne ( Fig. 62 ). Epigynal plate oval. Atrium wide. Copulatory openings inconspicuous. Copulatory ducts long, with two turns. Spermathecae oval. Fertilization ducts as long as spermathecae, directed toward clock 2:30 position from spermathecae.

Material examined. Holotype ♂ (IZCAS-Ar43978), Vietnam: Vinh Phuc, Tam Dao National Park, Disturbed Forest , Sieving , (21.4587°N, 105.6419°E, elev. 1084 m), 13 June 2007, Dinh-Sac Pham leg. Paratypes. 10♂ 10♀ (IZCAS-Ar43979– Ar43998), same data as holotype .

Distribution. Known only from the type locality.
