Etymology. Imazighen (plural) is the romanized name of Berbers, an ethnic group native to an extensive territory of North and West Africa.
Description. ♂ Medium-sized Oiketicoides species with finely scaled wings. Wingspan 23.0–25.0 mm, body length 11.0–12.0 mm, forewing length 10.5–11.5 mm, FI: 2.0,
Head. Antennae length 5.0– 5.6 mm with 36–41 segments, light brown, densely scaled. Pecten dark brown. Longest pecten is 14 times the length of the antennal segments’ length. Scapus and pedicellus covered with long straw-coloured scales. Head densely covered with long hair-like straw-coloured scales. Frons laterally broad covered with long dark grey, hair-like scales. Eyes large, black-grey, EI: 0.7.
Thorax. Legs are long light brown hairy. Thorax covered with long, dark grey-brown hair. Forewings are elongated, venation with r3+r4 on half length stalked, m2+m3 a quarter length stalked. Hindwing m1+m2 of one third length stalked, sc and rr fused and connected with dc at a third length. Wings are densely covered with dark greybrown, narrow scales with mostly 2 dentations, rarely one-pointed (Fig. 29). Fringes very narrowly lanceolate, predominantly with 2 dentations.
Abdomen. Dorsally and ventrally densely covered with long dark grey-brown hair-like scales.
Male genitalia (GU-030-2020, Sobczyk, GP 4073, 4074, 4089, 4090, Arnscheid). Total length 2.7 mm, width 0.7 mm. When closed, the valvae reach approximately the distal end of the tegumen, which is rounded, laterally on both sides clearly folded inwards. Valvae narrow, the distal end of the sacculus narrow, rounded and covered with 4–5 inwardly curved prominent sharp projections. Vinculum is narrow, medially with short appendages, saccus short, distally spoon-like widened and rounded. Phallus length 2.0 mm, elongated tubular, distally widened with a prominent hook-shaped projection (Figs 37, 59).
Distribution. Only known from the High Atlas in Morocco.
Diagnosis. The new species occur partially syntopic and synchronic with O. maghrebensis sp. nov. but it seems to be more local. It is easily distinguished from the latter by its darker wing colour and for the differences listed in the diagnosis section for O. maghrebensis sp. nov. It is also quite similar to O. maroccensis sp. nov., but it differs by its broader scales with 2–4 dentations.
