Oiketicoides algeriensis sp. nov.

( Figs 4 View FIGURES 1–6 , 20 View FIGURES 19–30 , 42 View FIGURES 35–44 , 54 View FIGURES 51–66 )

Type material. Holotype: • ♂: ALGERIA: Prov. El Djelva, Vis. El Djelva , 11.viii.1988, leg. Amar Medaoui, GU 017-2020 Sobczyk ( MWM).

Etymology. The species is named after its country of origin, Algeria.

Description. ♂. Smaller Oiketicoides species , wings evenly fine scaled. Wingspan 16.5 mm, body length 6.5 mm, forewing length 7.8 mm, FI: 2.0, antennae length 4.0 mm.

Head. Antennae blackish brown with 33 segments, densely scaled. Longest pecten of nine times length of the antennal segments. Head densely covered with long hair-like light brown scales. Frons with greyish brown hair-like scales; eyes large, blackish grey, EI: 0.6.

Thorax. Legs and thorax with long light brown hair. Forewings elongated, venation on forewing with r3+r4 stalked to a quarter length. M2+m3 stalked to a third length. Hindwing venation with m1+m2 half stalked, sc and rr fused and connected to dc at half length. Wings densely covered with light brown, very narrow single-pointed scales (class 2), occasionally distally notched (class 1), fringes very narrowly lanceolate, mostly with two dentations ( Fig. 20 View FIGURES 19–30 ).

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

Male genitalia. (GU-017-2020, Sobczyk). Total length 1.75 mm, width 0.6 mm. When closed, the valvae reach approximately the posterior end of the tegumen. Tegumen roundish, laterally on both sides clearly folded inwards. The valvae are narrow, the sacculus is narrower distally, rounded, with three distinctly sharp projections. Vinculum narrow, medially with short appendages, saccus elongated and narrow, somewhat widened and rounded distally. Phallus 1.4 mm long, elongated tubular, slightly S-shaped curved, distally widened with a distinct hook-shaped projection ( Figs 42 View FIGURES 35–44 , 54 View FIGURES 51–66 ).

Distribution. Only known from Algeria.

Diagnosis. Only the holotype is known. The new species is characterised by the very narrow pointed scales of class which are unique in the genus and only slightly similar to O. gracilis . This scales are extremely narrow and hair-like. The following class 2 scales ( Sauter & Hättenschwiler, 1999: 273) have very narrow lanceolate shape which is never the case in class 1.

It differs from the latter by its distinctly smaller wingspan and the special shape of the saccus, which is short, broad and roundish distally in O. gracilis and elongated and narrow in O. algeriensis sp. nov. It differs also from the other smaller Oiketicoides species mentioned in this paper by the less elongated and more roundish wing-shape.
