Supplementary description. ♂. Medium-sized tiny Oiketicoides species , wings evenly finely scaled. Wingspan 21.5–22.5 mm, body length 9.0– 9.5 mm, forewing length 11.0– 11.5 mm, FI: 2.0.

Head. Antennae length 5.0 mm, with 24–25 dark brown segments, densely scaled with yellowish brownish scales. Longest pecten is ten times the length of the antennal segments. Head densely covered with long hair-like light brown scales. Frons ventrally mixed with longer, slightly darker scales, eyes large, blackish-grey, EI: 0.5.

Thorax. Legs are long light brown hairy. Thorax long light brown hairy. Wings elongated, r3+r4 and m2+m3 one third stalked. On hindwings m1 and m2 very short stalked or one-point-rising, sc and rr are fused and connected with the dc by a bar at half length. Wings evenly thinly covered with light brown, very narrow scales, slightly more dense at the costal margin. Scales are almost hairy, one-pointed (class 1), exceptionally with two dentations, fringes verynarrow, one-pointedorwithtwodentations ( Fig. 21 View FIGURES 19–30 ).

Abdomen. Dorsally and ventrally densely covered with long light brown, hair-like scales.

Male genitalia. (slides GU-021-2020, Sobczyk, GU 2404, Hättenschwiler). Length 1.6 mm, width 0.45 mm. When closed, the valvae reach approximately the posterior end of the tegumen, which is tapered, laterally on both sides clearly folded inwards. The valvae are broad, the sacculus is rounded distally and shows 3 small, sharp extensions. The vinculum is narrow, mediolaterally with short projections, saccus short, distally hardly widened and rounded. Phallus length 1.0 mm, elongated tubular, almost straight, widened distally with a distinct hook-shaped projection ( Figs 43 View FIGURES 35–44 , 55 View FIGURES 51–66 ).

Distribution. Only known from Algeria (present publication) and Morocco ( Oberthür 1922; present publication).

Similar species. Oiketicoides nivellei is similar to O. gracilis and O. hampsoni . For diagnostic characters see above.
