Prasinocyma gemmifera sp. n.

( Figs 41 , 108 )

Holotype. ♀, Äthiopien [ Ethiopia, Southern Nations], Ostafrikanishes South Nation, Wushwush 7,4 km w, 1910m, 07°18’.16.05”N [07.304 N 36.057 E], 7.V.2013, Beck R. & R. Wanninger leg. ( BC ZSM Lep 78487; gen.prp. ZSM G 19663).

Paratypes. Southern Nations: 1♀, id. ( BC ZSM Lep 78483; gen.prp. ZSM G 16265); 1♀, Kumba Forest, 5km W Wushwush, 1890m, 15. – 25.IV.2014, leg. D. Wiersbowsky.

Description. Adult ( Fig. 41 ). Wingspan. Female 26 – 27 mm. Ground colour leaf green, without pale irroration. Forewing with small white spot at 1/2 of the inner margin. Small black discal dots on all wings. White, triangular terminal dots at vein endings of all wings, separated from the green ground colour by a very fine dark line. Fringe darker, slightly chequered. Hindwing termen slightly angled at M3. Length of female palpi 1.9 – 2.1 times diameter of eye, length of last segment 0.7 – 0.8 mm, tip and upperside palpi pale brown, underside white. Frons pale brown. Antennae filiform in female. Female hindtibia with four spurs.

Female genitalia ( Fig. 108 ). Apophyses fine and short. Sterigma slightly sclerotized, sub-rhomboid. Ductus bursae very narrow. Corpus bursae elongate oval, posteror half at both sides strongly spinose.

Differential diagnosis. Larger than P. albisticta and P. discipuncta sp. n., in wing coloration and external structure very similar to the former, but in genitalia strongly differing in the poor sclerotization of the sterigma and in the strongly spinose corpus bursae. Differential features from P. discipuncta sp. n. see under the following species.

Genetic data. BIN: BOLD:AAU2575, further specimens with identic sequence from Tanzania, Cameroon and Ghana. Nearest neighbours in Ethiopia: P. bifimbriata (4.2%), P. discipuncta sp. n. (4.4%). Genetically not far from P. salutaria (Swinhoe, 1904) (4.0%), distance from P. albisticta 6.9%, from P. niveisticta Prout, 1912 7.6%.
