Paratypes. Amhara: 2♂ 1♀, Ethiopia, Debark, Simien Mountains, Chennek Camp, 13°15’40”N / 38°11’40”E, 3633 m, Afro-alpine meadow/shrubland, 01-11-2011, leg. H. S. Staude; 3♂, Ethiopia, Debark, Simien Mountains, Sankaber Camp, 13°13’51”N / 38°02’25”E, 3250m, Afro-alpine meadow/shrubland, 31-10-2011, leg. H. S. Staude, coll. ZSM; 1♀ Äthiopien, 14 – 15.1.1996, Simien Mts., 3100 m, leg. W. Mey & K. Ebert, coll. MNHU (BC ZSM Lep 83215).
Other material examined: 1♂, Ethiopia, West Shewa, Ambo, 2200m a.s.l., V.2007, leg. V. Kravchenko & G. Müller (BC ZSM Lep 0 9922 (failure), gen. prp. G 19415).
Description. Adult (Fig. 35). Wingspan. Male and female 30 – 35 mm. In wing shape and coloration reminiscent of the nominotypical subspecies: ground colour of forewing leaf or bluish green, hindwing whitish with slight green tinge. Forewings without spot at the inner termen, black discal dot present, also on hindwing, here green. Terminal dots absent from all wings. Hindwing termen round. Male palpi very short, 0.6 – 0.7 times diameter of eye, palpi reddish, tip darker. Length of female palpi 1.0 – 1.2 times diameter of eye. Frons reddish. Antennae bipectinate in male, filiform in female. Antennal branches ochre. Male frenulum absent. Male hindtibia with four spurs, the proximal pair sometimes shorter or vestigial, pencil absent.
Male genitalia (Fig. 74). Uncus comparatively short. Valva with small subapical lobe, sacculus stout and sclerotized at tip not bent, with a narrow basal projection, parallel to the sacculus, slightly curved. Dorsal projection of sacculus comparatively long (0.85 mm). Aedeagus very long (2.0 mm). Sternum A8 with sclerotized weak bilobous projection at centre, with deep notch between.
Female genitalia (Fig. 102). Lamella postvaginalis sub-trapezoid, sclerotized. Lamella antevaginalis broad, membranous, but with two lateral, smooth sclerites. Antrum with a large, additional sclerite, longitudinally wrinkled, posterior margin irregularly shaped. Ductus and corpus bursae as in the nominotypical subspecies.
Differential diagnosis. In habitus reminiscent of the nominotypical subspecies, but on average slightly larger, green colour of forewings deeper, discal spot of hindwings usually present, in male genitalia the dorsal process of sacculus longer, aedeagus longer, posterior margin of sternum A8 deeper notched.
Genetic data. BIN: BOLD:ACL6986. Distance from nominate subspecies 1.3%.
Remarks. Male genitalia of one specimen from Shoa province (see above) better matching those of P. t. simienensis subsp. n. than those of the nominotypical subspecies. Not included in the type series because of the isolated locality and the poor condition of the specimen (wings rubbed and damaged).
Etymology. The name refers to the type locality in the Simien mountains.
