Prasinocyma perpulverata Prout, 1916

Prasinocyma perpulverata Prout (1916) : 143. Locus typicus: Somalia, Mandera (Holotype ♂ NHM, examined).

Material. In NHM there is a long series from Ethiopia, 'Dire Daoua', mentioned also in Prout (1930).

Redescription (P. p e r p ul v er at a). Adult small, wingspan in male 14 – 17 mm, in female 16 – 18 mm. Forewing narrow, hindwing termen rounded. Ground colour pale ochre, irrorated with dark brown scales, mainly on forewing. Male usually with much stronger forewing irroration, sometimes with very dar medial area, reminiscent of the coloration of P. l o ve r i dg e i (Prout, 1926), cf. Fig. 11 . Dark brown discal spot conspicuous, elongate on all wings, on forewing often blackish and not rarely curved. Length of male and female (!) palpi 0.9 – 1.1 times diameter of eye, pale ochre. Frons pale ochre, with some dark brown scales. Antennae bipectinate in male, filiform in female. Antennal branches ochre, markedly darker at base. Male frenulum present. Male hindtibia with four spurs, with pencil and with terminal process covering first tarsomere. Male and female genitalia not studied from P. perpulverata , but probably very close to those of P. l overi dgei (cf. Figs 52 , 88 ). Male genitalia of P. loveri dgei ( Fig. 52 ). Uncus short. Socii developed as short setose patches. Gnathos weakly sclerotized. Valva narrow, subapical ventral lobe at rather central position. Harpe short and broad. Aedeagus bent twice at centre, with sclerotized edge at 2/3, length 1.25 mm. Sternum A8 with two sub-truncate projections, sclerotized and concave between. In male genitalia reminiscent of those of P. hailei , mainly in the shape of aedeagus and sternum A8.

Female genitalia ( Fig. 87 ) Sterigma with two tapering posterior projections. Ductus bursae short, corpus bursae very small, membranous.

Remarks. Closely related to P. loveridgei (Prout, 1926) described from Tanzania and examined from a series from Kenya (ZSM). P. loveridgei may reveal to need to be downgraded to a subspecies of P. perpulverata , some Ethiopian specimens from the NHM series (' P. perpulverata ') are indistinguishable from our Kenyan P. loveridgei in habitus.

Genetic data. Not yet barcoded.
