P. strictus capitatus described by Jakovlev (1889) from northwestern China differs from the nominotypical subspecies in the same set of characters as P. strictus vernalis , but has the body paler, punctation denser, and head slightly larger. The structure of its male and female genitalia is similar to that of P. vernalis . Therefore, the author proposes to consider P. capitatus an Asian subspecies of P. strictus . The border between their ranges passes through the southern Transcaucasia and Northern Kazakhstan, and punctation and coloration of insects from the arid areas of the Caucasus and Transcaucasia (Daghestan, Milskaya Steppe) may be intermediate.

Diagnosis. The subspecies differs from P. strictus strictus in its paler body covered with fine dense paler punctation and in the larger head.

Description. Body sandy-colored to pale brown, covered with dense, fine, usually concolorous, occasionally brown punctures separated by intervals less than own diameter; surface not smooth. Underside pale, finely punctate. Abdominal segments with black punctation in corners of tergites. First and second antennal segments pale, 3rd–5th dark in middle parts. Length of body 7.8–10.8 (9.06) mm, b. lw 1.51–1.76 (1.66).

Head transverse [h. wl 1.08–1.26 (1.17)], medium-sized, l. bh 3.86–4.53 (4.19). Jugae longer than clypeus, widely rounded, running behind each other at apex, with weakly convex to slightly emarginate sides ( Fig. 92 ). Eye medium-sized, ds 1.36–1.57 (1.44). Antenna rather short, l. ba 1.94–2.3 (2.12).

Pronotum transverse [p. wl 2.16–2.79 (2.33)], with straight or slightly emarginate sides bordered with pale costa. Length and width of scutellum subequal, s. lw 0.87–1.12 (1.0).

Male ( Figs. 20 , 54 and 76) and female ( Fig. 1 , l. bb 9.0) genitalia typical of the subgenus.

Distribution. The subspecies is widely distributed in the southern part of Palaearctic Asia. In the west it reaches the southern slopes of Elburz Mts., in the southwest, the coast of the Persian Gulf, in the north, northern Kazakhstan, and in the east, Kashgaria and Mongolia. In the mountains it reaches a height of 2750 m.
