– Genital sac bare............................................................................................ 8

5. Tergite IX with median longitudinal ridge carrying 2–3 rows of about 20 strong points ( Fig. 82 D. E ), wing sheath with nose ( Fig. 82 A )....................................................................... P. mathildae Albu (p. 210)

– Tergite IX without median longitudinal ridge with strong points, wing sheath without nose.......................... 6

6. Genital sac (of both sexes) with ventral and apical spinules ( Fig. 101 C ), sternite IX otherwise bare.................................................................................................. P. trilobata (Edwards) (p. 265)

– Genital sac with basal spinules, apex bare, sternite IX with anterior spinules.......................................... 7

7. Tergal conjunctive III/IV and sternal conjunctives IV/V and VII/VIII in female all bare....... P. angusta (Edwards) (p. 256)

– Tergal conjunctive III/IV with about 2 spinules, sternal conjunctive IV/V with about 59 spinules, VII/VIII with about 72 spinules............................................................? P. forcipata (Goetghebuer) , male (p. 298)

8. Sternal conjunctives bare or with strongly reduced spinules.................................................... 9
