Description. Size. Length of pronotum in male 1.70–2.24 mm, in holotype 1.95 mm (mean 1.94 mm), in female 2.34–2.53 mm (mean 2.48 mm); N 11/9.

Structures. Tegmina of both sexes as in the preceding species narrowly tongue-shaped ( Figs. 5J, K ). Male. Lateral field of glandular pores on T2 broader and longer than in the preceding species, occupying slightly more than a fourth of the breadth of the tergite and more than half of the length of the pre-ridge area ( Figs. 5A , 6 G–L); T3 laterally along the anterior border also with glandular pores of partly relatively large size, but almost only in a single row ( Fig. 5A , white arrow); T8 with numerous small glandular pores mesally near the anterior border of T8 ( Fig. 5I ); T7 gland variable, without species specific features ( Figs. 5C , F–H); bristles along the posterior border of T2–7 shorter than in Dz. (P.) stenoptera ( Figs. 5 A–E, s. especially D, E); four scale sclerites present, none pleated (Fig, 7K, L).

Colouration. Disc of thoracal nota in both sexes extremely variable in colouration, reaching from almost completely light to completely dark ( Figs. 7 E-J), lightest males darker than the darkest of Dz. (P.) stenoptera , and darkest females still darker than the darkest of the former species; abdominal tergites of males much darker than in the preceding species, last tergites almost completely dark; legs always straw-coloured.

Distribution. Along the Saharan Atlas Range in Algeria up to the Aurès Mountains of Tunisia near the frontier to Algeria, between 2° and 8°30” of longitude ( Figs. 16 , 17 ).
