Etymology. Maghreb: Region of the North West African states.
Description. ♂ Medium-sized Oiketicoides species with evenly brown scaled wings. Wingspan 24.0–26.0 mm, body length 12.0– 13.5 mm, forewing length 12.0– 12.5 mm, FI: 2.0.
Head. Antennae length 6.0– 6.5 mm, densely light brown scaled, with 34–42 segments. Pecten dark brown, scales absent, ventrally long ciliated. Longest pecten of twelvefold antennal segment length. Head densely covered with long hair-like light brown scales, around the eyes a narrow border of dark brown scales, eyes large, black-grey, EI: 0.60–0.75.
Thorax. Legs and thorax long light brown hairy. Forewings are elongated, venation r3+r4 two-thirds length stalked, m2+m3 one-quarter length stalked. Hindwings venation m1 and m2 variable (from one third length stalked to divided), mediastam partially forked distally, sc and rr fused and connected with dc at a quarter length. Wings densely covered with medium brown, narrow scales. Scales two-pointed (classes 1–2), rarely single-pointed (class 2), fringes very narrowly lanceolate, predominantly with 2 dentations (Fig. 28).
Abdomen. Dorsally and ventrally densely covered with long, light brown hair-like scales.
Male genitalia. (GU-029-2020, Sobczyk, GP 4075, 4076, 4091, 4092, Arnscheid). Total length 2.6 mm, width 0.6 mm. When closed, the valvae reach approximately the distal end of the tegumen. Tegumen roundish distally, laterally on both sides clearly folded inwards. Valvae and sacculus narrow, rounded, distally covered with 5–6 very short spines. Vinculum narrow, medially with short extensions, saccus short, distally spoon-like widened and rounded. Phallus length 2.0 mm, elongated tubular, distally widened with a distinct hook-shaped projection (Figs 38, 60).
Distribution. Only known from the High Atlas in Morocco.
Diagnosis. Differs from the sympatric O. imazigheni sp. nov. by its much lighter ground colour. O. maghrebensis sp. nov. shows a smaller number of antennal segments and the diameter of the pecten is smaller (0.3 mm to 0.45 mm for O. imazigheni sp. nov.). The pecten appear almost contiguous, while those of O. imazigheni sp. nov. are more protruding and therefore considerably wider. The head is covered with light brown scales and show a narrow dark hem around the eyes. The head of O. maghrebensis sp. nov. shows a strongly contrasting straw colour and the frons are laterally broadly covered with dark greyish brown scales. The male genitalia of O. maghrebensis sp. nov. is elongated, the lateral edges almost parallel and the sacculus is covered with 5–6 very short spines. O. imazigheni sp. nov. on the other hand, has a long oval genitalia in general appearance and the sacculus shows distally four very prominent inwardly directed spines.
O. maghrebensis sp. nov. differs from O. maroccensis sp. nov. by the higher EI (O. maghrebensis sp. nov.: 0.6–0.75, O. maroccensis sp. nov.: 0.75–1.0), the mostly two-dentated scales (O. maroccensis sp. nov. have mostly narrower scales with one, rarely two dentations) and the fringe scales with mostly two dentations. The fringe scales of O. maroccensis sp. nov. show mostly four dentations. O. marrocensis sp. nov. is mostly slightly smaller, the termen is often oblique whereas the termen of O. maghrebensis sp. nov. is mostly roundish. The male genitalia of O. maghrebensis sp. nov. is elongated in general appearance, the lateral edges are almost parallel and the sacculus is covered with 5–6 very short spines. O. maroccensis sp. nov. on the other hand, has a long oval genitalia in general appearance and the sacculus shows distally 5–10 short pointed spines.
