DAEF PU).

Description. Adult ( Fig. 16 ). Wingspan. Male and female 27 – 35 mm. Ground colour from pale to deep leaf green, slightly irrorated with white strigulae. Forewing without spot at the inner termen., Terminal and discal dots absent from fore- and hindwings. Hindwing termen round. Palpi very short, length in male 0.5 times diameter of eye, in female 1.0 times; tip and upperside brown, underside white. Frons brown. Antennae bipectinate in male, filiform in female. Antennal branches pale ochre. Male frenulum present. Male hindtibia with four spurs, without pencil.

Male genitalia ( Fig. 57 ). Socii vestigial, reduced to small setose lobes. Saccus large, sclerotized, strongly bent. Valva narrow, subapical ventral lobe small. Sacculus sclerotized with a long basal process curved towards the distal end of valva. Aedeagus large (length 2.3 mm), with two slerotized lateral sclerites in the distal half. Sternum A8 with paired strongly sclerotized, stout, long lateral projections.

Female genitalia ( Fig. 90 ). Sterigma (lamella antevaginalis) sclerotized, large, reniform, at the lateroanterior edge with a round extension. Lamella postvaginalis sclerotized, with longitudinal furrows, laterally tapering. Ductus bursae of medium length. Corpus bursae oval.

Differential diagnosis. In habitus similar to P. gajdacsi but differing by evenly rounded hindwing termen (concave between veins in P. gajdacsi ), terminal dots absent; in genitalia reminiscent of P. tricolorifrons , the latter, however, with sacculus narrower and curved at tip, sternum A8 bilobous at posterior margin.

Genetic data. BIN: BOLD:AAY3238. Both barcoded specimens BIN-sharing, however not exactly matching their barcodes, at 1.4% distance, also showing slight differences in coloration. Nearest neighbours in Ethiopia: P. robusta sp. n. (4.6%), P. albivenata (4.7%). Genetically close to the aethaerea species-group, but also, to a certain extent, to P. jefferyi (distance 7.9% when considering all codons; particularly close when excluding the 3rd codon position), tentatively attributed to the nereis species-group here.

Etymology. The name refers to the type locality in Amhara province.
