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, 1996in 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. neimongolicawas 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. 1c-e, Fig. 2d-e). We considered both species conspecific with  P. neimongolicabeing regarded as a subjective junior synonym of  P. flavotincta( McLachlan, 1872)  syn. nov. 5236402304 1983-07-13 CAU Long Zhang.
