Coddingtonia chenyufengi Lin & Li , sp. nov. ( Figs 76 , 80A )

Etymology. The specific name is dedicated to Mr. Yufeng Chen (Beijing, China), who has helped us greatly with this research; noun (name) in genitive case.

Diagnosis. The female of the new species is similar to C. erhuan Feng & Lin, 2019 by the copulatory ducts coiling fewer than 4 times around the spermathecae. However, it can be distinguished by the copulatory ducts being wavy (vs. no obvious modifications).

Description. Female (holotype). Total length 1.56, carapace 0.55 long, 0.57 wide, opisthosoma 1.06 long, 0.79 wide. Eye sizes and interdistances: AME 0.04, ALE 0.04, PME 0.04, PLE 0.04, AME–AME 0.01, AME–ALE 0.01, PME–PME 0.02, PME–PLE 0.02, AME–PME 0.03, ALE–PLE 0. Chelicerae with 4 promarginal teeth. Leg measurements: I 2.12 (0.66, 0.70, 0.41, 0.35), II 1.86 (0.55, 0.64, 0.36, 0.31), III 1.39 (0.38, 0.46, 0.28, 0.27), IV 1.73 (0.51, 0.63, 0.32, 0.27).

Coloration ( Fig. 80A ). Carapace pear shaped, dark brown, darker medially, edge black, without pattern. Chelicerae, labium dark brown. Sternum tan. Legs dark brown, with dense setae. Opisthosoma conical, dark brown, surface with sparse long setae, venter darker than dorsum.

Epigyne ( Fig. 76 ). Epigynal plate nearly rectangular. Spermathecae barely visible through integument. Lateral wings of spermathecae kidney shaped. Copulatory ducts wavy, forming a semicircle ventrolaterally on wings, followed by 3 complete loops around the spermathecae. Spermathecae globose, almost adjacent. Fertilization duct directed at 10:30- o’clock-position from spermatheca.

Male. Unknown.

Material examined. Holotype ♀ (IZCAS-Ar44904), Vietnam: Hai Phong, Cat Ba National Park, Natural Forest, Sieving , 16.VII.2008, Dinh-Sac Pham leg.

Distribution. Known only from the type locality.
