Diagnosis.

The male of P. lata can be easily distinguished from other congeners, except for P. reniformis Xu & Li, 2007 and P. trifurcata Xu & Li, 2007 by having a short paracymbium and a large and blunt cymbial process (CP), with many cuspules. From P. reniformis , it can be distinguished by the short cymbial sclerite (CS), about 1/3 of the cymbial length, with a blunt tip (vs a long cymbial sclerite (CS) in P. reniformis , about 1/2 of cymbial length, with a sharp tip). From P. trifurcata , it can be distinguished by the bifurcated embolic process (EP) (vs the embolic process (EP) in P. trifurcata with a trifurcate tip) (cf. Fig. 3 A–C; Xu and Li 2007: figs 38-41, 49-54). The female of P. lata can be distinguished from all other congeners by the lip-shaped dorsal plate (DP) (vs dorsal plate narrow or indistinct) (Fig. 4A, B).
