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
,
26
). The female can be easily distinguished by the oval atrium and the short S-shaped spermathecal stalk (Fig.
27C
).
