slightly convex, interval 3 with two setigerous punctures adjoining stria 3; humerus well-marked with a small indistinct tooth; basal margin anteriorly concave, forming a weak acute angle (holotype) or an almost rectangular angle with lateral margin at the humerus. Setigerous pore present at base of a well-developed parascutellar stria. Microsculpture mesh pattern distinct, in males weakly transverse, in females isodiametric and slightly more stronger developed.

Prosternum (laterally), episterna and abdomen (laterally) with coarse and somewhat scattered irregular punctures, sometimes connected by shallow longitudinal ridges (last ventrites). Legs slender; mesotibia of males not dilated apically, metatibia not distinctly curved and without crenulation in internal side.

Male with median lobe of aedeagus strongly bent; apical shaft short and evenly rounded (Figs 10–11). Internal sac without thorns or teeth.

Known only from three localities situated not far from each other in the north-western region of Taza ( Morocco), in agricultural lands free of forests, at elevations about 300 to 450 m.
