Description. Adult ( Fig. 8 ). Wingspan. Male and female 25 – 34 mm. Ground colour bluish green, slightly irrorated with white strigulae. Forewings with white spot at ½ of the inner margin. Discal dots of hindwing developed as an elongate dark green streak towards costa, discal dots absent from forewings. Terminal dots absent from all wings. Hindwing termen usually slightly angled at M3. Length of male palpi 1.5 times diameter of eye, tip and upperside brown, underside white. In female 2.0 – 2.5 times length of diameter of eye. Frons deep green. Antennae bipectinate in male, filiform in female. Antennal branches pale ochre. Male frenulum present, weak. Male hindtibia with four spurs, with large projection at tip, covering half of first tarsomere.

Male genitalia ( Fig. 49 ). Uncus broad, tegumen extended to two plates. Valva with two spinulose crests and with basal elongate triangular process. Aedeagus very narrow and linear, length 1.65 – 1.85 mm. Sternum A8 sclerotized, with two shallow lobes, often irregularly shaped.

Female genitalia ( Fig. 85 ). Sterigma extended as a bipartite, alate sclerite. Lamella antevaginalis developed as a diffuse, irregularly shaped membrane. Ductus bursae long and narrow, posteriorly sclerotized. Corpus bursae large, oval. Signum absent.

Differential diagnosis. In male genitalia the two spinose crests on the valve distinguished from all other Prasinocyma species by the two spinose crests on the valve. The broad uncus and basal elongate triangular process reminiscent of the equivalents in the preceding species ( P. getachewi sp. n.) and P. s i m i a r i a, but clearly differing from both in the spinose crests on the valva, differing from P. simiaria also by the white spot at ½ of the inner margin of forewing. Basal projection of valva perhaps homologous to equivalents in P. pumilata and P. immaculata .

Genetic data. BIN: BOLD:ACL7685. Intraspecific variation low: 0.15% (n=3). Nearest neighbour in Ethiopia: P. getachewi sp. n. (1.7%), the latter being represented by a short sequence only, so far. Distance from P. bongaensis 3.6%.

Etymology. The name refers to Prof. Johann Baumgärtner, Molinis ( Switzerland), who worked for many years in Ethiopia, and shared entomological research with one of the authors.
