Type material. Holotype ♂ (DNA sample 25565 Lepid Phyl): Morocco, Ouarzazate Prov. , 1 km ESE Aguelmouss, N31.26232 W7.39616, 3.VII.2016, 2150 m, J. Tabell leg. (coll. MZH), BOLD sample ID: MM25565 . Paratypes: 2 ♂ (GP 5715 J. Tabell, DNA sample 25566 Lepid Phyl; DNA sample 25564 Lepid Phyl), with same collecting data as holotype (coll. TAB) .

Diagnosis. Pleurota pellicolor is characterized by an ochre forewing with indistinctly edged narrow pale ochre costal and median lines. In the male genitalia, the shape of uncus and the beak-shaped gnathos are characteristic.

Molecular diagnosis. All three specimens of P. pellicolor were sequenced, resulting in 658 bp, full-length DNA barcode fragments for two specimens, and a fragment of 573 bp for one specimen. The nearest neighbour to P. pellicolor is the morphologically distinctive P. gallicella with a 5.66% divergence. The barcodes of P. pellicolor exhibit no intraspecific variation (Table 1).

Description. Adult. Wingspan 24–25 mm. Labial palpus pale brown, mixed white and brown, ventrally widely dark brown, laterally with a small dark brown apical spot, long, about 7.4 x as long as diameter of eye (1 st and 2 nd segments), 3 rd segment long, 0.33 x length of 1 st and 2 nd segments. Scape dark brown, flagellum brown. Head white, tinged with pale brown, tegula and thorax concolorous with forewing. Forewing pale ochreous brown, apex slightly darker, costa narrowly pale ochre; subcostal line broad, parallel-sided, yellowish brown, extending from base to apex; two indistinct off-white narrow median lines. Fringe brown. Hindwing grey, fringe brown. Abdomen slightly lustrous, pale grey, each segment with transverse row of ochre scales.

Male genitalia. Uncus bell-shaped dorsoventrally, lined with several long bristles, proximal margin sinuous. Gnathos 1.5 x as long as uncus, funnel-shaped dorsoventrally, beak-shaped in lateral aspect, apical half moderately narrow, apex pointed. Valva upwards oblique, ventral margin evenly curved; sacculus narrow. Anterior extension of juxta straight, narrow; median part oval; posterior lobe narrow, reaching uncus; valval lobe elongate, base broad, apical part broadly folded, lined with several small nodules and short bristles. Vinculum U-shaped. Phallus curved, apex tapered, with one small elongate plate-shaped cornutus surrounded by numerous tiny spines.

Female genitalia. Unknown.

Biology. Unknown. The moths were collected at the beginning of July at light at dawn. The habitat is a steep slope at an elevation of 2150 m.

Distribution. Known from a single locality in the High Atlas mountains.

Derivation of name. The specific name refers to the coloration of forewing.
