- Posterior margin of subgenital plate with an incision.......................................................... 3

2 Lobes of metasternum longer (about 4mm), digitiform ( Fig. 4 C)........................................... P. carli

- Lobes of metasternum shorter, triangular........................................................... P. tibetensis

3 Body large, posterior margin of subgenital plate with an U-shaped or rimiform incision.............................. 4

4 Middle femur with spines on external side of ventral surface............................................. P. karnyi

- Middle femur with spines on both sides of ventral surface...................................................... 5

5 Ventral surface of styli without groove ( Figs. 1 C, 5F)................................................ P. carnarius

- Ventral surface of styli with a longitudinal groove............................................................6

6 Posterior margin of subgenital plate with a narrow incision (width almost 0.1mm) ( Figs. 1 A, 2H)........ P. crenatis sp. nov.
