Prasinocyma gajdacsi Prout, 1930

( Figs 30 , 69 )

Prasinocyma gajdacsi Prout (1930) : 25. Locus typicus: Ethiopia, Addis Ababa (Holotype ♀ NHM, examined).

Material. Oromia: 1♀, Bale (locality no. 65; BC ZSM Lep 81480); 2♂, Bale (no. 64; gen.prp. ZSM G 19649); 2♂, Bale (no. 57; BC ZSM Lep 81488; gen.prp. ZSM G 19530); 1♀, Bale (no. 91; BC ZSM Lep 81806, gen.prp. DAEF GT); 1♀, Bale (no. 86).

Redescription. Adult ( Fig. 30 ). Wingspan. Male and female 32 – 35 mm. Ground colour leaf green, irrorated with white strigulae. Forewings with a very pale yellowish dot at 1/2 of the inner margin, sometimes bordered by some brown scales. Fore- and hindwings with a black discal dot and small black terminal dots on the vein endings, the latter proximally accompanied by whitish dots. Hindwing termen concave between veins. Length of male palpi 0.8 times diameter of eye, tip brownish. Length of female palpi 1.5 times diameter of eye. Frons deep green. Antennae bipectinate in male, filiform in female. Antennal branches ochre. Male frenulum well developed. Male hindtibia with four spurs, at tip slightly projecting, pencil absent.

Male genitalia ( Fig. 69 ). Uncus narrow. Socii one third length of uncus. Valva broad, sub-rectangular, subapical ventral lobe conspicuous. Sacculus long, ending in a narrow, sclerotized harpe, slightly curved towards the ventral margin of valva. Length of aedeagus 2.0 mm, with narrow basal stalk, distally tapering, very broad in the central part, laterally with a round, projecting sclerite. Sternum A8 with two sclerotized broad truncate projections, deeply concave between.

Female genitalia exactly corresponding to those of the holotype, examined in the NHM ( Fig. 98 ). Sterigma large, slightly sclerotized, with two stronger sclerotized, round, lateroposterior sclerites. Ductus bursae short, corpus bursae small, both membranous, signum absent.

Differential diagnosis. To be distinguished from other Prasinocyma species especially by the conspicuous black terminal dots at the vein endings, with accompaining white dots proximally, and the conspicuously arched wing termen between the veins. In habitus somewhat similar to P. jefferyi , but somewhat larger, hindwing terminal dots more distinct, wings stronger suffused with white scales. In male genitalia reminiscent of P. triangulata Fletcher, 1958 from SW Uganda /NE Zaire but the latter with short, membranous, triangular projections on sternum A8 and the adult lacks the conspicuous terminal dots.

Genetic data. BIN: BOLD:ACL9892. Nearest neighbours in Ethiopia: P. aetheraea (8.1%) and P. neglecta (9.4%).
