Description. Adult ( Fig. 34 ). Wingspan. Male and female 27 – 35 mm. Fore- and hindwings narrower than in other species of the genus Prasinocyma ; ground colour of forewing leaf or bluish green, hindwing whitish with slight green tinge. Forewings without spot at the inner termen, black discal dot present, diffuse or absent on hindwing. Terminal dots absent from all wings. Hindwing termen round. Male palpi very short, 0.6 – 0.7 times diameter of eye, palpi reddish, tip darker. Length of female palpi 1.0 – 1.2 times diameter of eye. Frons reddish. Antennae bipectinate in male, filiform in female. Antennal branches ochre. Male frenulum absent. Male hindtibia with four spurs, the proximal pair sometimes shorter or vestigial, pencil absent.

Male genitalia ( Fig. 73 ). Uncus comparatively short. Valva with small subapical ventral lobe. Sacculus stoutly sclerotized, at tip not bent, dorsal projection narrow (length 0.7 – 0.75 mm), parallel to sacculus, slightly curved. Aedeagus narrow, comparatively short (1.5 – 1.55 mm), with two lateral sclerotizations, vesica granulated towards tip. Sternum A8 with sclerotized bilobous projection at centre, lobes close to each other and with a very small, shallow notch between.

Female genitalia ( Fig. 101 ). Lamella postvaginalis sub-rectangular or sub-trapezoid, sclerotized. Lamella antevaginalis broad, membranous, but with two lateral, furrowed sclerites. Antrum with a large, additional sclerite, longitudinally wrinkled, posteriorly bilobous. Ductus bursae short, sclerotized towards antrum. Corpus bursae membranous, globular. Signum developed as an inconspicuous transverse ridge.

Differential diagnosis. Clearly differing from all congenerics (except P. albivenata ) in the whitish hindwings, lacking male frenulum a.s.o. P. albivenata clearly differing in the white-marked forewing veins.

Genetic data. BIN: BOLD:ACL6986. Intraspecific variation elevated: maximum pairwise distance 1.8% (n=4). Nearest neighbours in Ethiopia: P. tricolorifrons (3.8%) and P. albivenata (4.1%).

Remarks. In the structure of the valva (despite great differences in wing coloration) reminiscent of P. albivenata , P. tricolorifrons and P. stictimargo .

Etymology. The name refers to Prof. Pasquale Trematerra, Campobasso ( Italy), for his support of studies on Ethiopian geometrids and for supervision of the co-author Francesco Parisi.
