Prasinocyma lutulenta Hausmann, Sciarretta & Parisi, 2016, sp. n.

Prasinocyma lutulenta sp. n. (Figs 27, 95) Holotype. 1 ♀, S. Ethiopa [Southern Nations], Gemu Gofa, Omo, Arba Minch, 1335m, 6.0161 °N, 37.5590 °E, 24.XII. 2013, leg. D. Wiersbowsky, coll. ZSM; BC ZSM Lep 81481 (failure), 85809; gen.prp. 16040. Description. Adult (Fig. 27). Wingspan. Female 32 mm. Ground colour pale bluish green, irrorated with white strigulae. Forewing without spot at the inner termen. Fore- and hindwings with an inconspicuous black discal dot, terminal dots absent. Hindwing termen slightly angled at M 3. Length of female palpi 2.0 times diameter of eye, tip and upperside reddish, underside white. Frons green, reddish towards vertex. Antennae filiform in female. Female genitalia (Fig. 95). Apophyses comparatively long. Sterigma semi-membranous with granulose surface, posteriorly with alate projections, anteriorly shallowly bilobous, bent upwards (ventrad). Ductus bursae long. Corpus bursae oval. Signum developed as a transverse sclerite, anteriorly with two spinules. Differential diagnosis. Several species are similar in habitus, e.g. P. aquamarina sp. n., P. monikae sp. n. and P. beryllaria sp. n., the last two being available only in the opposite sex but clearly distinct in their COI barcode. P. aquamarina sp. n. differs also in female genitalia in its shorter ductus bursae and the stronger slerotization of the furrowed sterigma. The 'closest' genetic ally P. amharensis differs from P. lutulenta sp.n. in the completely lacking discal dots, in female genitalia in the strikingly different shape of the sterigma. Genetic data. BIN: BOLD:ACL 9893. Nearest neighbour in Ethiopia: P. amharensis sp. n. (9.4 %), distance from an undescribed Prasinocyma species (Tanzania, province Iringa) 6.8 %. Genetically strongly diverging from all other species (> 150 species) so far barcoded from the African continent, thus a description based on a single female seems justified. Etymology. The name refers to the red and green frons and palpi, lat. lutulentus = multicolorous.Published as part of Hausmann, Axel, Sciarretta, Andrea & Parisi, Francesco, 2016, The Geometrinae of Ethiopia II: Tribus Hemistolini, genus Prasinocyma (Lepidoptera: Geometridae, Geometrinae), pp. 1-63 in Zootaxa 4065 (1) on page 27, DOI: 10.11646/zootaxa.4065.1.1, http://zenodo.org/record/27049
