Redescription. Body length 6.0– 12.8 mm. Head glossy black to brown-black, with isolated punctation and wrinkles or almost smooth. Labrum, anterior part of clypeus and palpi yellow-brown to brown, mandibles red-brown to black, with black tips; posterior part of clypeus glossy red-brown. Antennae brown, extend beyond pronotum midlength, with loose trimerous club. Head including eyes slightly broader than anterior width of pronotum, vested with long, erect, pale setae; eyes large, protruding, separated by less than one eye’s width. Ventral surface glossy dark brown.

Prothorax slightly longer than wide (length = 1.2–2.3 mm, width = 1.0– 2.1 mm; mean length to width ratio 1.00: 1.15), anterior part subparallel, widest in middle, constricted towards base. Pronotum yellow-brown to black brown, glossy, almost smooth, with very isolated, fine punctation; anterior transverse depression slightly bulging, vested with long, erect, pale setae. Ventral surface yellow-brown to dark brown, glossy, prosternal process narrow, dilated distally; hypomera short, broadly rounded; procoxal cavities broadly open posteriorly.

Scutellum transverse-ovate, yellow-brown to dark brown. Anterior mesoventral process strongly protruding.

Elytra yellow-brown to dark brown, long (length = 3.8–8.8 mm, width = 1.3–3.1 mm; mean length to width ratio 1.00: 2.72), subparallel to very slightly dilated behind middle, apices slightly bevelled to straight. Basal third of each elytron with longitudinal oblong, dark brown macula (mostly not reaching suture or side margin); apical macula dark brown, reaching suture, but not side margin, apically V-shaped emarginate with yellow. Sometimes yellow ground color reduced to transverse macula across both elytra, expanding anteriorly and posteriorly. Punctation consists of ten rows of fine punctures, almost reaching apex; larger interval present between rows I and II; puncture diameter conspicuously smaller than interstices. Surface vested with long, erect, pale setae.

Legs long, pale yellow-brown to dark brown, tips of femora, base of tibiae and tarsi dark brown. Metatibiae slightly curved, not reaching apex of elytra; carina continuous; with long, erect, pale setae.

Abdomen yellowish-brown, whole ventral surface with long, erect, pale setae.

Distribution. So far recorded from northern Africa (Libya, Egypt), the Arabian Peninsula (Saudi Arabia, Yemen, Oman), Israel and Iran ( GERSTMEIER 2010). First record from Socotra Island.
