Description. Adult ( Fig. 2 ). Wingspan. Male and female 21 – 27 mm. Ground colour bluish green, irrorated with white strigulae, without spot at the inner termen. Discal dots absent from forewing. On hindwing discal dot developed as an elongate dark green streak towards costa of hindwing. Terminal dots absent from fore- and hindwings. Hindwing termen usually slightly angled at M3. Length of male palpi 1.2 times diameter of eye, tip and upperside brown, underside white. Female palpi very long, 2 – 2.5 times diameter of eye. Frons brown. Antennae bipectinate in male, filiform in female. Male frenulum very weak. Male hindtibia with white pencil and four spurs.

Male genitalia ( Fig. 44 ). Comparatively small. Valva narrow, ventral membranous lobe prominent, harpe narrow, pointed, short. Aedeagus very narrow, bent at 1/2, length 1.7 – 1.8 mm. Sternum A8 with paired, narrow, straight, long lateral projections.

Female genitalia ( Fig. 81 ). Lamella antevaginalis bilobous posteriorly, corpus bursae small, sub-globular.

Differential diagnosis. Very similar to nominate subspecies in habitus and genitalia, but differing in ventral membranous lobe of valva at 1/2, in specimens from western Africa at 3/4. Projections of sternum A8 slightly shorter and stouter in the new subspecies. For differences from P. pseudopedicata see following species. Genetic data. BIN: BOLD:AAF8220. Intraspecific genetic variation elevated (maximum pairwise distance 1.7%), distance between nominate subspecies ( Sao Tome, Cameroon) and subsp. aethiopica 0.8%. Nearest neighbour: P. pseudopedicata (1.6%).

Etymology. The name refers to the type locality in Ethiopia.
