Prasinocyma albivenata Herbulot, 1983

( Figs 36 , 75 , 103 )

Prasinocyma albivenata Herbulot (1983) : 14. Locus typicus: Ethiopia, [Bale Mts.], Dinsho (Holotype ♀ MNHN Paris, 3 paratypes examined in coll. Herbulot-ZSM, one barcoded: BC ZSM Lep 76125).

Material. Oromia: 2♀, Bale (locality no. 25; BC ZSM Lep 13152; gen.prp. ZSM G 19405); 1♀, Bale (no. 33; BC ZSM Lep 18069); 1♂, Bale (no. 36; gen.prp. DAEF GQ1); further examined type material from Ethiopia, see above.

Redescription. Adult ( Fig. 36 ). Wingspan. Male and female 30 – 35 mm. Wings narrower than in other species of the genus Prasinocyma . Ground colour of forewing leaf green, with conspicuous white streaks on the veins; hindwing whitish, with slight green tinge towards termen. Forewings without spot at the inner termen. Black or brown discal dot present on forewings, but absent from hindwings. Terminal dots absent from all wings. Hindwing termen round. Length of male palpi 1.0 times diameter of eye, palpi brown. Length of female palpi 1.2 times diameter of eye. Frons whitish with pale green scales. Antennae bipectinate in male, filiform in female. Antennal branches ochre, at base slightly darker. Male frenulum absent. Male hindtibia with four spurs, pencil absent.

Male genitalia ( Fig. 75 ). Uncus short. Valva with small ventral, subapical lobe, slightly sclerotized. Sacculus broadly sclerotized, at tip rounded, basal projection stout, tapering. Aedeagus short (1.4 mm), and narrow. Sternum A8 with sclerotized bilobous projection, deeply notched at centre.

Female genitalia ( Fig. 103 ). Sterigma with two rounded anteriolateral projections, hut-shaped in the centre, with small posterior notch. Antrum dilated, with paired lateral sclerites. Ductus bursae of medium length (0.8 mm). Corpus bursae small, globular. Signum present with sclerotized transverse fold.

Differential diagnosis. Clearly differing from all congenerics in the white-marked forewing veins.

Genetic data. BIN: BOLD:AAF8221. Intraspecific variation low: 0.8% (n=3). Nearest neighbour in Ethiopia: P. trematerrai sp. n. (4.1%).

Remarks. In the structure of the valva (despite great differences in wing coloration) reminiscent of Prasinocyma trematerrai sp. n., and P. tricolorifrons (see above).
