Etymology. The specific name is derived from the type locality; noun in apposition.

Diagnosis. Male of Pseudopoda yintiaoling sp. n. resembles P. daliensis Jäger & Vedel, 2007 in having a similar disc-shaped embolus and by the presence of an embolic projection (Figs 33–34, 38–40; Jäger & Vedel, 2007, figs 79–90), but can be distinguished by: 1) embolic projection large, hook-shaped in prolateral view in P. yintiaoling sp. n. (Figs 33, 38; small, triangular in P. daliensis ); 2) distal end of embolus broad with round tip in ventral view in P. yintiaoling sp. n. (Figs 33, 38; narrow with pointed tip in P. daliensis ); 3) RTA apical margin with a small tooth in between the vRTA and dRTA in P. yintiaoling sp. n. (Figs 34, 40; tooth absent in P. daliensis ); 4) vRTA longer than wide in P. yintiaoling sp. n. (Figs 39, 40; wider than long in P. daliensis ). Epigyne resembles P. wuxi sp. n. in having the similar outline of epigynal field (Figs 35, 36, 42, 43; Figs 24, 25 , 31, 32) but can be distinguished by the posterior bulges of lateral lobes like small hump in P. yintiaoling sp. n. (Figs 35, 42; somewhat round in P. wuxi sp. n.).

Embolus arising from 9-o’clock-position on tegulum; conductor membranous, sheet-like.

Coloration ( Figs 3 , 37): Carapace yellowish, with many dark spots and linear trident pattern. Chelicerae yellowish, with brown spots; labium, gnathocoxae, coxae and sternum yellowish. Legs yellowish, with small spots and slightly larger spine patches. Dorsal opisthosoma yellowish, with dark patch above heart and two lateral dark bands, the latter posteriorly fused to transversal line, behind that a light transversal line and a dark posterior part, two pairs of sigilla; venter yellowish, with black patches.
