Running it though the Nartshuk's key (2016) you would end up at P. ruficornis, but her illustrations of the genitalia are not particularly detailed and neither the posterior view nor the ventral view show the clear tooth on each of the gonostyli, though the posterior view she gives may hint at an apical narrowing. Checking Ismay's thesis, both the posterior and ventral views of the genitalia show the apicalnarrowing, but he also illustrated a gonostylus at maximum width (possible at 45 degree angle between posterior and ventral views) and that seems a good match with your last illustration. So, yes, this is P. ruficornis.
