Aedeagus as in Fig. 20 . Distribution: Benin, Guinea, Nigeria, Sierra Leone.................................................................................................................... P. intersecta

3 Pronotum 1.50 times as wide as long, densely covered with fine punctures, hind angles indistinct, widely rounded. Head, pronotum, scutellum and the underside black, elytra orange, with a black spot behind humerus and a black irregular transverse band behind the middle ( Fig. 5 ). Body length: 5.60–7.60 mm. Aedeagus as in Fig. 18 . Distribution: Namibia................................................................................................................................................. P. elegans

- Pronotum 1.60–1.75 times as wide as long, nearly impunctate, usually completely orange or orange with black spots (except the dark forms of P. c ro c a t a with black pronotum), hind angles more or less indicated ............................... 4

4 Aedeagus with alae triangularly dilated ( Fig. 19 ). Pronotum usually with three black spots (two lateral, one median) ( Fig. 7 ). Paler specimens often with pronotum uniformly orange ( Fig. 6 ), darker specimens with the black spots connected. Body length: 7.10–10.40 mm. Distribution: countries of southern coast of West Africa (from Senegal to Cameroon) ............................................................................................................................................... P. gambiensis

- Aedeagus with alae not triangularly dilated ................................................................................................................ 5

5 Frons narrow in males (1.20–1.40 times as broad as the diameter of the eye)............................................................ 6

- Frons broad in males (2.00–2.44 times as broad as the diameter of the eye) .............................................................. 7

6 First protarsomere 1.25 times as long as broad in male. Coloration variable ( Figs. 2–4 ): 1) head and pronotum orange, elytra with a postmedian black band only, 2) elytra with a black spot at the first third near suture and a postmedian black band, 3) head and pronotum black. Body length: 7.20–8.75 mm. Aedeagus as in Fig. 17 . Distribution: Yemen, Saudi Arabia..................................................................................................................................... P. c ro c a t a

- First protarsomere 1.5 times as long as broad in male. Head and pronotum orange, elytra orange with one small round spot at one third of elytra near suture and one elongate and slightly oblique band ( Fig. 1 ). Body length: 6.10– 8.75 mm. Aedeagus as in Fig. 16 . Distribution: Sultanate of Oman............................................ P. cervenkai sp. nov.

7 Elytra semiopaque, relatively roughly punctured. Head usually orange with a broad black band from eye to eye on frons, elytra usually with a black apical spot ( Fig. 15 ). Body length: 5.35–7.15 mm. Aedeagus as in Fig. 26 . Distribution: Sudan, Chad............................................................................................................................... P. traegaordhi

- Elytra semiopaque to lustrous, finely punctured.

8 Ratio length of elytra/length of pronotum 3.70–4.10. Pronotum with a basal black band with irregular anterior margin ( Fig. 14 ) or with two basal black spots. Body length: 8.00– 9.90 mm. Underside of aedeagus without impressions ( Fig. 25 ). Distribution: Guinea-Bissau, Senegal ........................................................................................... P. signata

- Ratio length of elytra/length of pronotum 3.35–3.50. Only the darkest specimens with apical black spots on elytra. Coloration very variable (see the description) ( Figs. 10–13 ). Body length: 6.60–8.70 mm. Underside of aedeagus with one longitudinal and two apical rounded impressions ( Figs. 22–24 ). Distribution: North-East Africa, Arabian Peninsula and Near East ........................................................................................................................ P. sennariensis
