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.).
