Type material.

Holotype: China • 1 ♂; Henan Province, Nanyang City, Xixia County, Erlangping Town; 33.524°N, 111.688°E; 11 April 2013; F.X. Liu leg.; HN-013-001. Paratype: China • 1 ♂; same data as for the holotype; HN-013-002.

Diagnosis.

Males of P. erlangping sp. nov. resemble those of P. heteroidea but can be distiguished from the latter by the tegulum having one curved furrow (Fig. 3A ), while P. heteroidea has two furrows (see fig. 6 in Xie and Yin (1991)), and by the longer cymbium flange (Fig. 3D ; see fig. 8 in Xie and Yin (1991)); from those of P. albimana by the longer embolus, larger cymbium flange and thicker retrolateral tibial apophysis (Fig. 3A, D ; see fig. 12B-D in Wanless (1978)); from those of P. assamensis , P. fimbriata , P. labiata , P. orientalis , P. quei , P. xishan sp. nov., P. taiwanica , and P. zhaoi by the embolus being shortest (Fig. 3A ; see figs 10D, 7C, and10A in Wanless (1978), fig. 6 in Murphy and Murphy 1983, fig. 661 in Peng et al. (1993), and fig. 4B in Zhang and Li (2005), respectively); in addition, from those of P. assamensis and P. fimbriata by the cymbium flange being thickest and longest (Fig. 3D ; figs 10F, 7G in Wanless (1978), respectively); from those of P. labiata by the larger cymbium flange and thicker retrolateral tibial apophysis (Fig. 3D ; see fig 10B in Wanless (1978)); from those of P. orientalis , P. quei , P. taiwanica and P. zhaoi by the bar-shaped retrolateral tibial apophysis (Fig. 3D ; see fig. 6 in Murphy and Murphy 1983, and fig. 4D in Zhang and Li (2005), respectively).

Palp. Tibia with 3 apophyses, ventral one thick and short, intermediate one relatively slender, retrolateral one largest and bar-shaped in dorsal view (Fig. 3A-D ). Embolus short and stout (Fig. 3A ). Seminal duct clear and S-shaped. Tegulum with a deeply curved furrow and a membraneous apophysis (Fig. 3A, B ).
