Sobczyk, Thomas & Arnscheid, Wilfried R., 2021, Taxonomic revision of the North-African species of the genus Oiketicoides Heylaerts, 1881 (Lepidoptera: Psychidae: Oiketicinae), Zootaxa 4975 (3), pp. 483-508 : 494-495

Oiketicoides atlanticum sp. nov.

( Figs 9 , 25 , 44 , 57 )

Type material. Holotype: • ♂: MOROCCO: occ. Sidi Bouk-nadel-Tankstelle, zw. Kenitra und Rabat , 50 m, 15.x.2004, leg. L. Lehmann (barcoding Psy-0147- Sobczyk ) ( MWM).

Etymology. Atlanticus (lat., adj.): in old Latin: belonging to the Atlas Mountains.

Description. ♂ Medium-sized Oiketicoides species , wings evenly finely scaled. Wingspan 19.0 mm, body length 10.0 mm, forewing length 9.2 mm, FI: 2.0.

Head. Antennae length 5.0 mm, light brown with 36 segments, densely scaled. Pecten dark brown. Longest pecten of thirteen times length of the antennal segments. Head densely covered with long hair-like light brown scales. Frons laterally with dark grey-brown hair-like scales, eyes large, black-grey, EI: 0.6.

Thorax. Legs and thoraxlong light brownhairy. Forewings elongated, venation r3+r4 very short stalked, m2+m3 one quarter length stalked. Hindwings venation m1 and m2 one third length stalked, sc and rr fused and connected with the dc at a third length. Wings are densely covered with medium brownish narrow scales, with 2 or rarely 3 dentations. Exceptionally multi-pointed (usually class 3, fig. 25). Fringes very narrowly lanceolate, predominantly with 2 dentations.

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

Male genitalia (GU-018–2020, Sobczyk). Total length 1.75 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. The valvae are narrow, sacculus is narrower distally, rounded, with four prominent sharp projections. Vinculum narrow, medially with short appendages, saccus short, distally somewhat widened and rounded. Phallus length 1.4 mm, elongated tubular, slightly s-shaped curved, distally widened with a distinct hook-shaped projection ( Figs 44 , 57 ).

Distribution. Only known from the type locality.

Remark. This easily recognisable species seems to be very rare. Beside the holotype no other specimen have been collected.

Diagnosis. O. atlanticum sp. nov. differs from the other species by the relatively wide, distally notched scales of the forewings in connection with likewise narrow, distally notched fringes. The species resembles O. oberthueri , but differs from this species by much longer antennae, wider wings and genital structure. Tegumen and vinculum of O. oberthueri are elongated elliptically connected.
