(HNU-YHY25); 1 ♂, Tengchong County, Jietou Township, Datang Village Daheling Ganjiao (25°25.21'N, 98°24.57'E, 1878 m alt.), 19.V.2006, X.J. Peng et al. leg. (HNU-PWH060519); 1 ♂, same data as HNU-PWH060519 (CAS-PWH060519).

Etymology.

The specific name is a patronym in honour of Prof. Xianjin Peng (College of Life Sciences, Hunan Normal University), one of the leading spider taxonomists of China; noun (name) in genitive case.

Diagnosis.

This new species is very similar to E. yunnanensis in appearance, but can be distinguished from the latter by: 1) having a thread-like terminal apophysis vs. not thread-like (Figs 13A, B and 18C ); 2) the straight and pointed embolus vs. curved and non-tapering embolus (Fig. 13A ); 3) the branches of the median apophysis about 45° apart vs. very close to each other (Figs 13A, B , 18C ); 4) a pair of rhomboidal copulatory openings vs. arcuate (Fig. 14B, D ). It is somewhat similar to E. yaoi sp. nov. by the copulatory organs and the habitus, but differs in having: 1) a thread-like terminal apophysis vs. bifurcated (Figs 9A, B , 18A ); 2) straight embolus vs. curved (Fig. 9A ); and 3) a pair of rhomboidal copulatory openings vs. arcuate (Figs 10B, D ).
