- Vertex of head not elevated, cranial pits entirely exposed (Fig. 12).............................. P. grandipennis (Pic)

2. Meso-frontal ridge between posterior cranial excavations sharply defined, acutely elevated, carinate, distinctly separating posterior excavations (Figs. 14–15); elytra conspicuously “ribbed” or costate; elytral apices acutely, separately rounded (Fig. 13)..................................................................................... P. kasantsevi Young

- Meso-frontal ridge between posterior cranial excavations rather flat, indistinctly separating posterior excavations (Figs. 2–3, 8–10); elytra inconspicuously costate; elytral apices broadly rounded (Figs. 1, 7)................................... 3

3. Margin of hooded cranial vertex deeply emarginate, vertex bilobed (Figs. 1–3); antennal scape not strongly rounded, bulbous distally (Fig. 4)....................................................................... P. bilobatus sp. nov.

- Margin of hooded cranial vertex gradually, more shallowly emarginate (Figs. 7–9); antennal scape enlarged and strongly rounded distally, bulbous (Figs. 8–9)..................................................... P. cinnabarus sp. nov.
