Supplementary description. ♂ Medium-sized Oiketicoides species with finely scaled wings. Wingspan 23.0– 28.0 mm, body length 11.5–13.4 mm, forewing length 12.0– 13.3 mm, FI: 2.0.

Head. Eyes large and round, EI: 0.54 (n=4). Frons and vertex covered with light brown hair-like scales, darker laterally. Antennae length is 7.0– 8.1 mm with 35–36 segments, pecten dorsally covered with light brown lanceolate scales. The longest pecten reach 10–12 times the length of the antennal segment. Scapus ventrally and distally densely covered with light brown lanceolate scales.

Thorax. Broad, robust and densely covered with woolly hair-like dark brown scales. Legs covered with light brown hair-like scales. Forewing venation with r3+r4 free emanating or short stalked and m2+ m3 from one point rising or free emanating. Wings light, greyish-brown to dark brown, evenly relatively thinly scaled. Scales partly one-pointed (class 2), more often double-pointed (mainly class 2, Fig. 35 ). Fringes bright brown, clearly longer than other wing scales, lanceolate, distal with 3–5 dentations. Hindwing venation: sc+rr with a bar after half length to the anterior margin of the dc, m2 and m3 free running, rising from one point or very short stalked. Hindwings more thinly scaled, with smaller scales than on forewings, with one or two dentations. Fringes like on forewings.

Abdomen. Dorsal and ventral covered with long hair-like brownish yellow scales. Distinctly brighter than the thoracic scales.

Male genitalia. (40-2020, 41-2020, 42-2020, Sobczyk, GP4068, 4071, Arnscheid). Tegumen and vinculum elongated elliptically connected, distal end of tegumen sclerotized, trapezoidally rounded, laterally on both sides clearly folded inwards. Medially notched, covered with scattered fine setae. Valvae reach the distal end of tegumen, distally covered with fine long setae, sacculus distally covered with 7–10 sharp spines. Vinculum narrow, distally clearly widened, medially with short hemispherical extensions, saccus very long, reaching about a quarter of the total genital length, distally slightly widened and rounded. Partially medially with edge-like folding. Phallus about two thirds of the total genital length, elongated tubular, slightly curved, vesica distally widened with distally slightly pointed hammer-shaped projection ( Figs 35 , 62 ).

Distribution. Widespread in Morocco ( Oberthür 1922; present publication), Tunisia ( Chnéour 1947).

Similar species. The robust and woolly shape of O. lefevrei is unique in the whole genus. It could, therefore, not be confused with any other Oiketicoides species.

Diagnosis. Distinctive, easily recognizable by its broad, robust and densely with woolly hair-like scales covered thorax and abdomen.
