Material examined.

EGYPT: Aegyptus, Faggala (1♀, NMPC); Le Caire (1♀, MNHN). ISRAEL: Arava-Tal, S Zofar, 18.II.1987, 0 m, leg. Schawaller & Schmalfuss (1♂, SMNS). YEMEN: Lahj, X.2000, malaise trap, leg. A. v. Harten & A. Sallam (1♂ 1♀, SMNS).

Diagnosis.

Most similar in overall appearance and small size to Singilis turcicus , but with pronotum strongly transverse and pronotal punctures spaced twice as far apart as those on the head.

Redescription.

Length 4.5-4.8 mm. Winged. Ferrugineous or testaceous red with a dark preapical sutural spot reaching interval 4 or 5 (Fig. 16).

Head obtuse, rather wide, slightly convex to flat between the eyes, with numerous large and deep punctures (mixed with wrinkles near eyes) that become sparser towards the neck. Frons without punctures. Eyes large and convex.

Pronotum punctate, slightly wrinkled, transverse, subconvex, considerably broader than head, strongly rounded in front, with anterior angles effaced. Sides rounded, with a long sinuation in front of posterior angles, which are acute. Pronotal margin broadly explanate, basal impressions fairly deep. Pronotal base projected at the middle, median furrow moderately wide and deep.

Elytra approximately 1/3 longer than broad, sides subparallel, almost obliquely truncate at apex which is weakly sinuate. Striae, including the scutellar stria, fairly deep and finely punctate; intervals weakly convex, with two pores on interval 3.

Microsculpture strong, especially on forebody where the cells are small and rather isodiametric, but cells become more transverse towards the sides of pronotum. Elytra with finer microsculpture of larger, subquadrate cells, and thus appearing shinier than the forebody.

In male, protarsomeres I–III slightly dilated.

Aedeagus - Fig. 35. Aedeagal median lobe elongate, straight, with notch in middle, emphasized by a thickening in the manner of a sagittal crest. Tip of aedeagus slightly curved to right. Internal sac with small spicular field made up of small spines.

Distribution.

Egypt (country record), Israel (country record), Saudi Arabia, Yemen.
