43. Profemora strongly thickened, well twice as thick as meso- and metafemora ( Figs 1 View FIGURE 1–8 ; 13 View FIGURE 9–16 ). Tibiae reddish. Prothorax about as long as wide. Vestiture of prothorax consisting of loosely spread greenish scales, also present along middle. Elytra and prothorax with uniform scales, interrupted only by glabrous punctures standing in series on elytral intervals. Green scales on elytra mostly homogeneously covering surface. Scales bright green, raised hairs inbetween brown and little longer than width of elytral intervals ( Fig. 6 View FIGURE 1–8 ). Elytral apex simple in both sexes ( Figs 1–2 View FIGURE 1–8 ; 13–14 View FIGURE 9–16 ).................................................................................................. Ph. brenskei 4.6–5.5 mm ( Greece: Peloponnese).

- Profemora extraordinarily thickened, three times as thick as meso- and metafemora ( Figs 3–4 View FIGURE 1–8 ; 9–10 View FIGURE 9–16 ). Tibiae reddish-brown and/or blackish. Prothorax transverse, laterally strongly rounded. Vestiture of prothorax with scales on each sides, not along middle. Scales on elytra patchy with gabs inbetween and/or stripe along suture without scales ( Figs 3–5 View FIGURE 1–8 ; 9–10 View FIGURE 9–16 )......... 43a

43a. Tooth of profemora in shape of an acute triangle ( Figs 3–4 View FIGURE 1–8 ). Tibiae dark black. Vestiture of prothorax with scales along both sides, from fore to hind margin. Scales on prothorax and elytra (bluish-) greenish, scales on elytra fan-shaped ( Fig. 7 View FIGURE 1–8 ), erect hairs inbetween light brown, about as long as width of an interval. Suture on elytra without scales ( Figs 3–4 View FIGURE 1–8 ). Elytral apex in females conspicuously prolonged ( Fig. 12 View FIGURE 9–16 )............ Ph. nigrofasciatus 5.0– 6.9 mm ( Turkey: Bozdag, Afyonkarahisar).

- Tooth of profemora in shape of an equilateral triangle ( Fig. 9 View FIGURE 9–16 ). Tibiae dark or brownish/reddish. Vestiture of prothorax with scales denser towards hind margin. Scales on prothorax and elytra light green, often with golden shimmer, oval to drop-shaped. Elytra only sparsely set with scales, erect hairs inbetween blackish, pointed, longer than width of two interstriae ( Figs 9–10 View FIGURE 9–16 ). Elytral apex in females only inconspicuously mucronate ( Fig. 11 View FIGURE 9–16 )....... Ph. occultatus 4.5–5.5 mm ( Greece, Peloponnese).
