Supplementary description. ♂. Medium-sized Oiketicoides -species, uniformly brown coloured, wingspan 18.0–20.0 mm. Body length 9.2–10.5 mm, forewing length 10.4–10.8 mm, FI: 2.0.

Head. Antennae length 4.0– 4.6 mm, with 29–30 segments. Eyes large, round; EI: 0.77 (n=4). Frons and vertex covered with grey, hair-like scales, darker laterally. Scapus ventrally and distally densely covered with dark brown, lanceolate scales, antennal segments dorsally covered with dark brown, lanceolate scales. Longest pecten reached 12–14 times the length of the antennal segments.

Thorax. Narrow, slender, covered with dark brown scales. Legs covered with brown hair-like scales. Forewings venation r3+r4 and m2+ m3 short stalked. Dc partly with an intercalated cell formed by the divided mediastam. Ground colour dull dark brown, uniformly thinly scaled. Cloaking scales wider than in the other species listed here, shorter, stalked, with 2–3 dentations (classes 2–3) median only slightly indented ( Fig. 31 View FIGURES 31–34 ). Fringes light yellowbrown with a silky shine, distinctly longer than other wing scales, lanceolate, distally with 2–3 dentations. Hindwings venation with m2 and m3 distinctly long stalked.

Abdomen. Dorsally and ventrally covered with long brownish yellow hair-like scales, lighter than on thorax.

Male genitalia (GP 4068, Arnscheid; 49–2020, 50–2020, 51–2020, Sobczyk). Total length 2.3–2.5 mm, 0.6–0.7 mm wide. The tegumen and vinculum are connected in an elongated elliptical shape, the distal end of the tegumen is sclerotized, elliptical, rounded distally, and laterally folded inwards on both sides. Medially hardly noticeable notches, covered with scattered fine setae. Valvae clearly protrude beyond the distal end of the tegumen, distally covered with fine long setae. The distal end of the sacculus is covered with 4–5 (exceptionally up to 8) small inwardly pointed curved projections. Vinculum narrow, distally slightly widened, medially with broad drop-shaped projections. Saccus very long, reaching about a quarter of the total genital length, distally pointed. Phallus length 1.7–2.0 mm, about two thirds of the total genital length, elongated tubular, slightly curved medially, vesica widened distally and hook-shaped pointed ( Figs 46 View FIGURES 45–50 , 64 View FIGURES 51–66 ).

Distribution. Occurs in the Middle and High Atlas of Morocco ( Lucas 1934; present publication).

Diagnosis. In Central Morocco the species occurs often in great numbers, especially in the Middle Atlas. This small and relatively broad-winged species cannot be confused with any other Oiketicoides species in North Africa, except for O. chottella and O. pseudochottella sp. nov., which differ clearly in size and genital structure. The wings of O. chottella and O. pseudochottella sp. nov. are more elongated, the wingspan is 22.0– 27.7 mm. The male genitalia differs in the tegumen and saccus. The tegumen of both species mentioned are rounded, not elliptical and the sacci are short, laterally widened where attached at the vinculum, drop-shaped, while in O. hurei the tegumen is elliptical and the saccus is very long, reaching about a quarter of the total genital length, distally pointed. The phalli in O. chottella and O. pseudochottella sp. nov. are also shorter than in O. hurei , as long as 1.65 mm, elongated tubular, distally widened with a distinct thorn-shaped extension.
