Type material. Holotype: ♂, Tunesien, ca. 10 km W Kasserine, unterh. Chambi NP, 800 m, 10.x.2006, leg. J. Gelbrecht, T. Drechsel & D. Stadie (GU 124-2021 Sobczyk).

Paratypes: 11 ♂, same data as holotype, 8 ♂, Tunesien, Prov. Kaserine, Wadi am Djebel Chambi, 850 m, 12 km südl. Kaserine 08. –11.x.2006, leg. D. Stadie, J. Gelbrecht & T. Drechsel (in coll. Stadie, Gelbrecht, Drechsel, CTS, CWA, SMNS).

Diagnosis. ♂. Wingspan 21.0– 23.5 mm (average: 22.6 mm), forewing length 10.6–11.0 mm, width 5.4–6.0 mm (average 5.6 mm), FI 1.88–1.98 (average 1.94 mm). Head EI 0.72–0.77 (average 0.74). Antennae length 6.2–7.4 mm, 38–43 segments without pedicellus and scapus. The pecten very long, 1.4 mm. The longest pecten 10 times of segment diameter. Thorax and abdomen densely covered with long pale brown hairs. Forewings broad, costal margin almost straight, apex rounded, termen curved. All wings brownish, forewing costal margin darker, thinly scaled with hair-like scales (class 1–2 after Sauter & Hättenschwiler 1999), scales mostly with two dentations, partially with one or three dentations. Fringes lighter greyish brown, long, with 3 dentations, the middle of them mostly broader and larger. Abdomen densely covered with long pale brown hairs.

Male genitalia. (GU 124-2021 Sobczyk): 2.1 mm length, elongated in general appearance, tegumen rounded distally, laterally bulging, covered with short hairs. Valvae long and clearly extended beyond the distal end of the tegumen. The valvae are apically rounded and covered with short setae. Sacculus closure elongated, slender, distally narrower and apically with four short thorns.Anellus short, pointed. Vinculum broad, laterally evenly curved. Saccus elongated, slightly wider distally. Phallus longer as genitalia length (2.3 mm), straight or slightly bent, with distinct roundish enlargement caudally, vesica with short cornuti.

Discussion. A small species (wingspan 21.0– 23.5 mm) with relatively short and wide wings (FI below 2.0) and thus differ from the similar species (FI above 2.0). The species is also characterized at first glance by its relatively monochrome, densely scaled brown wings.

Distribution. As far as known from the type locality in Tunisian.

Bionomics. Unknown

Etymology. The species is named after the type locality.The Djebel Chambi (arabic: Dschebel asch-Schaʿânabî) is a mountain range with the national park of the same name, in which the highest point in Tunisia is located at 1544 meters.
