Diagnosis: P. pyrenaella is a small species which externally resembles the Spanish species P. hebetella and P. amaurodoxa , but the forewing is paler. The male genitalia can be distinguished from those of P. hebetella by narrower uncus, the shape of gnathos (smaller area with scobination, apex less rounded) and narrower valval lobe. Compared to P. amaurodoxa , the uncus is shorter, the gnathos narrower, and the posterior lobe of juxta shorter. In the female genitalia of P. pyrenaella , both apophyses are shorter, and the posterior signa and the spines of anterior signum are shorter.

Molecular data: Seven specimens of P. pyrenaella were sequenced, resulting in 658 bp (n=6) and 654 bp (n=1) barcodes. The nearest neighbour to P. pyrenaella is P. amaurodoxa , with a 3.49 % divergence. The barcodes of P. pyrenaella exhibit 0.15 % intraspecific variation.

Description: Adult. Wingspan 10.5-14 mm, one male 15.5 mm. Labial palpus mixed with off-white, brown and pale brown scales, ventrally darker, in female paler, about 5.1x as long as diameter of eye (1 st and 2 nd palpomeres), 3 rd palpomere 0.4x length of 1 st and 2 nd palpomeres. Antenna brown, 0.75x length of forewing. Frontal tuft, neck, tegula and thorax off-white, mixed with pale brown. Forewing densely covered by off-white, pale brown-tipped scales, without longitudinal lines and dark spots, except for off-white costal line from base to 1 / 2, in female forewing is more ochre. Fringe off-white with brown median line. Hindwing and fringe dark grey. Abdomen slightly lustrous, dark grey, each segment with a transverse row of ochre scales.

Male genitalia: Uncus thimble-shaped from ventral view, elongate, lined with several bristles of different length, distal margin concave. Gnathos 1.5x as long as uncus, funnel-shaped from ventral view, evenly tapered towards apex, largely smooth, with shallow medial and apical crests, medially surfaced by small nodules. Valva elongate, upwards oblique, thimble-shaped; sacculus long, covered with long bristles. Anterior extension of juxta straight, narrow and long; median part with a broad plate; posterior lobe almost reaching the apex of uncus, apex with a small tooth; valval lobe elongate, upwards oblique, apex evenly rounded, lined with several long bristles, apical half parallel-sided, basal part bulged. Phallus curved, parallel-sided, apex acute, with one weakly sclerotized cornutus and a group of numerous tiny spines, apical 1 ⁄ 4 with a wedge-shaped sclerotization.

Female genitalia: Papilla analis ovoid, narrow, apical half covered with bristles. Posterior apophysis 3.75x as long as papilla analis and 1.5x as long as anterior apophysis, which is 1.5x as long as segment 8. Segment 8 longitudinally elongated, membranous, quadrate, dorsolaterally reinforced by sclerotized band; branch of anterior apophysis apically fused, U-shaped, weekly sclerotized; ventral longitudinal sclerotization narrow, shorter than segment 8. Antrum tubular, sclerotized, parallel-sided. Ductus bursae slightly expanded towards corpus bursae. Corpus bursae rounded, with one arched broad signum with two protuberances, and two leaf-shaped signa.

Biology: Unknown. The specimens were netted in the afternoon around Genista sp. , females were swept from white-flowering chrysanthemums.

Distribution: Known only from northern Spain.

Derivation of name. The specific epithet refers to the collecting area.
