Prasinocyma fallax sp. n. (Figs 32, 71) Holotype. 1♂, Ethiopia, Prov. Oromiya [Amhara], ZW. Debre Sina & Sembo, Umg. Debre Sina, N09°35.0650, E39°44.417, 06.IV.2010, 2730 m—lux, leg. H. Sulak, coll. M. Sommerer (BC ZSM Lep 40508; gen.prp. G 19457). Description. Adult (Fig. 32). Wingspan. Male 32 mm. Wing coloration appearing as pale whitish-green ground colour strongly irrorated with dark green, forming diffuse patches with different intensity of green, forewing costa red. Forewings without spot at the inner termen and without discal dots. On hindwings, discal spot developed as elongate diffuse dark green streak towards costa. Small black terminal dots on all wings. Hindwing termen slightly concave between veins. Length of male palpi 0.8 times diameter of eye, palpi reddish, underside irrorated with white 'hairy' scales. Frons reddish. Antennae bipectinate in male, antennal branches ochre. Male frenulum present. Male genitalia (Fig. 71). Valva with conspicuous subapical ventral lobe. Centre of valva with a long and broad corrugate fold. Sacculus sclerotized, broad, the distally curved, spinose tip overlapping with the broad part of sacculus. Aedeagus with two cornuti, stalk about 1/4 of aedeagus length (1.7 mm). Sternum A8 sclerotized with paired, rounded, sub-truncate projections. Differential diagnosis. In habitus without clear differential features from P. a e t h e r ae a, terminal dots less conspicuous, dark green irroration slightly finer. Differences in male genitalia clear-cut, see differential diagnosis under P. aetheraea. Genetic data. BIN: BOLD:AAY3243. Nearest neighbour in Ethiopia: P. aetheraea (3.3%). The sequences are identic when excluding the 3rd codons from analysis. Etymology. The name refers to the external similarity with its sister species (P. aetheraea), latin fallax = misleading.
