Diagnosis. The male can be distinguished from other Zoropsis species by the strong embolus that originates prolaterally from the tegulum, extending along the cymbial margin to the distal side of the tegulam and forming an arc in ventral view. The female can be distinguished by the epigyne with an unfolded and slender scape with a narrow stalk and the vulva with the ovoid bodies hidden below the copulatory ducts. Description.

Paratypes : 2 females , with same data as holotype (Inner Mongolia Normal University, Hohhot, China ). These are the specimens that Tang et al. (1999) misidentified and described as the male of Zoropsis pekingensis . Song et al. (1999, 2001) based their illustrations on Tang et al. (1999) . Etymology. This specific name is a patronym in honour of Prof. Guiming Tang of lnner Mongolia Normal University, China , who collected the type specimens. Diagnosis. Females of the new species are similar to Z. pekingensis ; both have a median scape and small ovoid bodies on epigyne ( Figs 15–16 , 20–21 ). Males of both species have a small and membranous conductor, hook-like median apophysis and RTA on male palp ( Figs 17–19 , 22–24 ), but can be distinguished by the smaller, narrower and shorter embolus and the large median apophysis on the male palp. Females can be differentiated by the wider median scape and the smaller ovoid bodies. Description. Male ( holotype ).
