Diagnosis: P. sobriella is characterized by olive-brown forewing with narrow white lines. The shape of gnathos and valval lobe in the male genitalia, and thick and long apophyses in the female genitalia are distinguishing details.

Molecular diagnosis: Five specimens of P. sobriella were sequenced successfully, resulting in 658 bp (n=3), 611 bp (n=1) and 572 bp (n=1) sequences. The nearest neighbour to P. sobriella is P. subnobilella with a 1.66 % divergence. The barcodes of P. sobriella exhibit 0.56 % intraspecific variation.

Description: Adult. Wingspan 22-24 mm. Labial palpus ochre, ventrally mixed white and brown, dorsolaterally with a dark brown apical spot, about 7.3x as long as diameter of the eye (1 st and 2 nd palpomeres), 3 rd palpomere 0.35x length of 1 st and 2 nd palpomeres. Antenna brown, basally mixed with white scales. Frontal tuft and neck ochre, tegula and thorax yellowish olive-brown. Costal line narrow, indistinctly edged, from near base to 2 / 3; subcostal line yellowish olive-brown, parallel-sided; median line white, narrow, not connected to dent of median line, which forms a separate narrow line from base to tornus; fringe line off-white; dorsal line narrow and short; median area yellowish olive-brown, in female paler. Cilia grey, apically off-white. Hindwing and cilia dark grey. Abdomen slightly lustrous, dark grey, each segment with a transverse row of ochre scales.

Male genitalia: Uncus thimble-shaped from ventral view, lined with several bristles of different length, apex blunt. Gnathos 1.9x as long as uncus, from ventral view elongate, funnel-shaped, medially covered with small nodules, apical half narrow, parallel-sided, apex blunt. Valva elongate, upwards oblique; cucullus thimble-shaped. Anterior extension of juxta straight, short, median part rounded, posterior lobe extended to uncus, apex armed with a small tooth. Valval lobe well sclerotized, very broad, rounded apically, covered with several small nodules and short bristles apically. Phallus curved, tapered towards apex, apex pointed, with one robust plate-shaped cornutus surrounded by numerous tiny spines.

Female genitalia: Papilla analis ovoid, covered with bristles of different length. Apophyses very long; posterior apophysis 10x as long as papilla analis and 1.6x as long as anterior apophysis. Segment 8 elongated longitudinally, rectangular, membranous, dorsolaterally reinforced by sclerotized band, lined with a few bristles distally, ventral longitudinal sclerotization narrow, as long as segment 8, branch of anterior apophysis narrow. Antrum tubular, short, membranous, anterior 1 / 3 tapered and sclerotized. Ductus bursae membranous, moderately broad, parallel-sided. Corpus bursae ovoid, with one robust arched signum bearing two serrated, thorn-like protuberances, and two leaf-shaped signa.

Biology: Unknown.

Distribution: Spain.

Remarks: The designation by Lvovsky is unpublished, and according to the ICZN (1999, Article 74.7) it is not valid. Consequently, one original specimen is designated herein as a lectotype.
