Figs 5A–G , 6A–E

Type material. Holotype ♂, China, Yunnan Province, Yuxi City, Xinping County, Ailao Mountain Natural Reserve , Jinshan Yakou to the Chama Gudao (23°56′967″N, 101°30′270″E), 19 May 2011, Zongxu LI leg . Paratypes: 3♀, same data as for holotype, Zongxu LI and Guchun ZHOU leg .

Etymology. The species name is derived from the Latin word ‘ longus ’, referring to the long embolus; adjective.

Diagnosis. The new species is similar to P. bifidus ( Yin et al., 2004: 271, figs 1–7) in having a similar RTA, but can be distinguished from it by: 1) longer embolus (short in the latter); 2) larger COs (small in the latter); 3) thicker CD (thin in the latter). The new species is similar to P. qiqiensis ( Yin et al., 2004: 272, figs 8–10), but can be distinguished from it by: 1) bursae oval relatively (kidney-shaped in the latter); 2) higher location of COs (low in the latter); 3) thicker CD (thin in the latter).
