Material examined. Holotype male ( CAU): CHINA, Inner Mongolia, Xing’an League , 1983.VII.13, leg. Long Zhang.

Additional materials: 1 female, China, Jilin Province, Antu County, Songjiang River before Baixi hotel, 42.0564° N, 127.5983° E, 9.VII.2015, leg. Zehui Kang ; 1 male and 1 female, Russia, Amurskaya Oblast, Amur R. Basin, Kasatkino village , Ganukan River , mouth, 48.95639° N 130.12199° E, 13.08.2003 , leg. T. Tiunova.

Distribution. This species is widespread in the Eastern Palearctic. It occurs in China (Inner Mongolia, Jilin Province, Xinjiang), the Korean Peninsula, Mongolia, and in Russia (East Siberia and south of the Far East).

Remarks. Yang & Yang (1996) did not evert the aedeagus of P. neimongolica Yang & Yang, 1996 in the original species description. They merely noted that it is externally similar to P. indentata Wu & Claassen, 1934 . Upon examination of the holotype, the dissected penis of P. neimongolica was almost indistinguishable from that of P. flavotincta ( Figs. 1 , 2 ). Some minor differences were noted in the shape of the apex in the anterior hemitergal process on tergum 10 ( Fig. 1b , Fig. 2c ) and the fork of the penial tube lobes of both species ( Fig. 1 c-e, Fig. 2 d-e). We considered both species conspecific with P. neimongolica being regarded as a subjective junior synonym of P. flavotincta ( McLachlan, 1872) syn. nov.
