Diagnosis
Externally, P. apenninana sp. nov. resembles P. schawerdae but the male genitalia are different. The vesica in P. apenninana sp. nov. has a larger right part than in P. schawerdae; the angle between the axes of the phallus and right diverticulum is smaller (maximum 90°) than in P. schawerdae (100–120°). The phallic process in P. apenninana sp. nov. is shorter, wider and not strongly curved; the opposite is the case in P. schawerdae. Both the wing colouration and male genitalia distinguish P. apenninana sp. nov. from P. alpinana sp. nov., P. frigidana and P. cantabriana sp. nov. The vesicae of P. apenninana sp. nov. and P. cantabriana sp. nov. are similar but the angle between the axes of phallus and right diverticulum in P. cantabriana is larger.
Etymology
The specific name is a feminine adjective derived from the name of the Apennines.

Description
Male (Fig. 1G)
HEAD. Frons devoid of scales (worn specimens), vertex yellow brown, labial palps creamy. Antennae with scapus and pedicellus brown dorsally and creamy ventrally, flagellum with creamy scales.
THORAX. Dorsally, including tegulae, with yellow and brown scales, ventrally whitish, fore- and middle legs brown, hindlegs white. Forewing length 7.2–7.4 mm (n =2), upperside deep yellow, with remnants of rust dorsal blotch, cilia concolorous with upperside, underside dark grey, with white scales in costal area. Hindwing upper- and underside dark grey, with white costal area and white longitudinal line between veins M 1 and M 2 starting from discal cell and ending in cilia.
ABDOMEN. Grey.
GENITALIA (Fig. 2D). Valva with weak curvature, appears slender but this may be due to preparation. Rest of valva, uncus and socii very similar to those of P. schawerdae. Transtilla (Fig. 3D) large, round. Phallus (Fig. 6 C–D) slightly curved ventrally, with wide and blunt medioventral process (Fig. 4 F–G), with apex curved to the right. Vesica in general resembles that of P. schawerdae, with large main part protruded at right from sclerotized phallus and two large diverticula bearing long, robust cornuti. Small, conical undulating structure (diverticulum) emerges ventrally from main part. Gonopore located dorsally, surrounded by semicylindrical sclerotized plate with minute, lentiform tubercles. Main part medially constricted by circular furrow in which gonopore is sunk. Portion located distally of furrow very large, heart-shaped in dorsal view. Main part of vesica looks ovoid in lateral left view. Diverticula emerge from right portion in opposing directions, right one straight, emerging from ventral half of right part and directed laterally, left one curved and also pointed laterally. Length and orientation of diverticula relatively constant. Axes of right diverticulum and sclerotized phallus form an angle of maximum 90°. Cornuti aciculate, capitate, of equal length, left one slightly bent. Barely discernible acanthae present on left portion of main part of vesica and at end of diverticula.
Female
Unknown.
Molecular data(Table 1, Fig. 9)
BIN URI: BOLD:ACA9597. The maximum intraspecific divergence of the barcode region is 0% (n= 2). The minimum distance to the nearest neighbour, P. schawerdae from the Dinaric Mts is 3.69%.
Ecology
Preimaginal stages and larval host plant are unknown. The moths fly in July. Habitat: the type material was collected in alpine grassland above the treeline.
Distribution(Fig. 10)
Apennine Mountains.
