Paratypes : 11 males and 39 females , same data as holotype . Etymology. The specific name refers to the type locality; adjective. Diagnosis. This new species is similar to L. reticulopecta Lin & Li, 2010 , but can be distinguished by the presence of eight promarginal cheliceral teeth and three small retromarginal teeth ( Fig. 27C ); one short spine on the earlobe-shaped process of palpal tarsus ( Figs 24D , 26B ); the scimitar-shaped median apophysis in the male ( Figs 24B , 27D ); and the absence of slender hairs on the margin of spermathecae and sperm ducts in the female ( Figs 25C , 27B ).

Tip of the bulb ( Figs 24B , 27D ): median apophysis scimitar-shaped, conductor lamellar, embolus triangular. Opisthosoma brown. Female (one of the paratypes ): similar to male in coloration and general features, but with a smaller body size and shorter legs. Total length 2.00 ( Figs 25A–B ). Prosoma 1.00 long, 0.87 wide.
