Diagnosis.

The male of this species is similar to that of Pararana gaofani Lin & Li, 2022 ( Lin et al. 2022: 217, figs 17A-C, 18A, B) in having the cymbium with a notch and the swollen patella, but can be easily separated by the patella with seven short tooth-like spines (vs four long relatively thick spines), the tibia with a thick spine (vs absent), the long lamellar median apophysis (vs the relatively short horn-like median apophysis) and the slightly curved rod-like embolus (vs horn-like) (Figs 25B-D View Figure 25 , 26 View Figure 26 ). The female can be easily distinguished by the oval atrium and the short S-shaped spermathecal stalk (Fig. 27C View Figure 27 ).

Femur with four rows of short strong spines ventrally, dorsally, and prolaterally; patella expanded, with seven stout spines; tibia with a very thick spine retrolaterally. Cymbium with a notch subapically.
