(Figs 37, 76, 104)

Prasinocyma bifimbriata Prout (1930): 157. Locus typicus: South Africa: Transvaal, Three Sisters (Holotype ♀ TMP Pretoria).

Material. Oromia: 1♂ 11♀, Sidama (locality no. 11; BC ZSM Lep 45466, 45467, 81818; gen.prp. ZSM G 19412, 19418, 19466); 2♀, Agere Maryam (no. 48); 4♀, Finchawa (no. 61); 1♀, Sidama (no. 50); 2♀, Sidama (no. 96; BC ZSM Lep 84767, 84768); 1♀, Aluweya (no. 51). Southern Nations: 2♂ 1♀, Arba Minch (no. 24; BC ZSM Lep 13187, 13188; gen.prp. ZSM G 19413); 1♂, Arba Minch (no. 26; BC ZSM Lep 13189; gen.prp. ZSM G 19452).

Redescription. Adult (Fig. 37). Wingspan. Male and female 18 – 22 mm. Ground colour warm leaf green, without pale irroration. Forewing without spot at 1/2 of the inner margin. Small dark green discal dots and a black terminal line on all wings. Fringe yellowish white. Hindwing termen very slightly angled at M3. Length of male palpi 1.0 – 1.2 times diameter of eye, pale ochre, tip concolorous. Length of female palpi 1.7 – 2.0 times diameter of eye. Frons pale brown. Antennae bipectinate in male, filiform in female. Antennal branches ochre, darker at base. Male frenulum weak and short. Male hindtibia with four spurs, without pencil.

Male genitalia (Fig. 76). Uncus stout, short. Socii vestigial. Saccus very long. Valva broad with ventral margin stongly bulbed at 1/3 and with small subapical ventral lobe. Costa of valva with a basal membranous process and a small digitiform process at 1/2, usually bent ventrad. Juxta developed as V-shaped ‘pocket’, reminiscent of equivalents in genus Thalassodes . Aedeagus long (2.4 – 2.55 mm) and narrow, with a long, lateral, spinulose ridge. Sternum A8 with two membranous, rounded projections, with a deep central notch.

Female genitalia (Fig. 104). Sterigma not sclerotized. Antrum slightly sclerotized, cup-shaped. Ductus bursae membranous. Corpus bursae membranous, elongate pyriform. Signum oval, with sclerotized, longitudinal fold. Female genitalia of Ethiopian populations well matching those of an examined slide from South Africa (NHM).

Differential diagnosis. In habitus very similar to P. bilobata Fletcher, 1978, the latter, however, in male genitalia clearly differing in the small saccus and the stout, long dorsal spine from costa of valva.

Genetic data. BIN: BOLD:AAK2813. On BOLD three genetically identic specimens from South Africa, Zimbabwe and Rwanda. Intraspecific variation low: 0.18% (n=7). Nearest neighbour in Ethiopia: P. gemmifera (4.2%). Genetically not far from P. angulifera (6.5%), Prasinocyma niveisticta Prout, 1912 barcoded from Kenya, Cameroon, Bioko (6.5%) and P. salutaria barcoded from Kenya (7.1%). Lophorrhachia rubricorpus at a distance of 7.7%.

Remarks. For generic combination see remarks to the preceding species and to the bifimbriata species-group. Prout (1930) generally records this species for " Abyssinia ".
