Type material.

Holotype • ♂ (SWUC -T-LY-28-01), China, Yunnan Prov., Gongshan Co., Dulongjiang Township. 27°40'43"N, 98°16'13"E, elev. 1155 m, 3 April 2012, Zhi-Zhong Yang leg. Paratype • 1 ♀ (SWUC -T-LY-28-02) with same data as for holotype .

Etymology.

The specific name comes from the word “ Dulong ”, the name of one of the Chinese ethnic minorities that live adjacent to the area inhabited by the new species; noun in apposition.

Diagnosis.

The new species resembles Z. puellula (Simon, 1898) (Sankaran and Sebastian 2017: 148, figs 3 A – G) in having bifurcated lateral apophysis and short-widen posterior lip of epigyne (Figs 2, 3 C – H), but can be differentiated by the ventral arm of lateral apophysis somewhat rectangular in retrolateral view (Figs 2 A, 3 C, E) (vs somewhat triangular); cylindrical heads of spermathecae (Figs 2 D, 3 H) (vs somewhat circular).
