Sphingius gongsunsheng Lin & Li , sp. nov. ( Figs 13 , 14C )

Etymology. The species is named after Gongsun Sheng, one of the 108 outlaws in the classical Chinese literature Outlaws of the Marsh; noun in apposition.

Diagnosis. The female of the new species is similar to S. hainan Zhang, Fu & Zhu, 2009 (see Zhang & Fu, 2010) by the extremely enlarged epigynal hood, but it can be distinguished by the hood being longer than wide (vs. as long as wide in S. hainan ).

Description. Male (holotype). Total length 6.32; carapace 2.20 long, 1.81 wide, opisthosoma 4.12 long, 2.28 wide. Eye sizes and interdistances: AME 0.12, ALE 0.15, PME 0.15, PLE 0.14, AME–AME 0.05, AME–ALE 0.04, PME–PME 0.03, PME–PLE 0.06, AME–PME 0.07, ALE–PLE 0.08. Chelicerae with three promarginal and eight retromarginal teeth. Leg measurements: I 6.52 (1.81, 2.34, 1.32, 1.05), II 5.60 (1.61, 1.90, 1.12, 0.97), III 4.75 (1.31, 1.53, 1.11, 0.80), IV 7.67 (2.05, 2.53, 1.98, 1.11). Leg spination: III tibia 2-2v, metatarsus 1-1v; IV tibia 4pv, 2rv, metatarsus 2-2v.

Coloration ( Fig. 14C ). Carapace, chelicerae, endites, labium and sternum dark brown. Legs brown. Opisthosoma oval, grey with black setae. Spinnerets short, yellow.

Epigyne ( Fig. 12 ). Hood oval-rectangular. Copulatory openings in hood. Spermathecae posteriorly located, large, globose; gland anteriorly located, smaller, globose; a short connecting tube between gland and spermatheca.

Male. Unknown.
