Prasinocyma bongaensis sp. n.

( Figs 4 , 82 )

Holotype. ♀, Äthiopien [ Ethiopia, Southern Nations], Ostafrikanischer Graben, Provinz South Nations, Bonga, 12km E, 2414m, 07° 17.652 N 36.22.567 E, 23.VI.2014, Beck, R. & G. Riedel ( BC ZSM Lep 84753; gen.prp. ZSM G 15909).

Paratypes. 3♀, id.

Description. Adult ( Fig. 4 ). Wingspan. Female 28 – 31 mm. Ground colour bluish green, irrorated with white strigulae, without spot at the inner termen. Discal dots absent from forewing. On hindwing discal spot developed as a small, elongate, oblique dark green streak. Terminal dots absent from fore- and hindwings, but a fine, dark green terminal line present. Hindwing termen slightly undulate, slightly angled at M3. Length of female palpi 2.0 – 2.5 times diameter of eye, tip and upper side red brown. Frons red brown. Female antennae simple, filiform, in the proximal third with small intersegmental incisions.

Female genitalia ( Fig. 82 ). Lamella postvaginalis strongly sclerotized, rectangular. Lamella antevaginalis trapezoid, concave anteriorly. Ductus bursae long and narrow. Corpus bursae elongate pyriform. Signum absent.

Differential diagnosis. In habitus very similar to P. p e di c at a, larger but hindwing termen more undulate and slightly angled. In female genitalia with long and narrow ductus bursae reminiscent of P. baumgaertneri sp. n. but sterigma less extended and antrum broader. The genetically closest species, P. tranquilla , is much smaller and furthermore differs clearly in the missing strigulae, in the narrower forewing shape, in the paler, bluish ground colour, and in the broad ductus bursae of female genitalia.

Genetic data. BIN: BOLD:ACN8258. Nearest neighbours in Ethiopia: P. tranquilla (4.6%), P. baumgaertneri sp. n. (5.5%), P. pedicata aethiopica subsp. n. (5.6%), P. h ai l e i (6.4%).

Etymology. The name refers to the type locality near Bonga.
