Prasinocyma corrugata Fletcher, 1958

( Figs 19 , 60 )

Prasinocyma corrugata Fletcher (1958) : 84. Locus typicus: Kenya: Aberdare Range, Mt Kinangop, 8000 ft (Holotype ♂ NHM, examined).

Material. Oromia: 1♂, Bale (locality no. 40; BC ZSM Lep 81812 (failure), 85807; gen.prp. DAEF GO1); 1♂, Bale (locality no. 64; gen.prp. ZSM G 19653).

Redescription. Adult ( Fig. 19 ). Wingspan. Male 34 – 36 mm. Ground colour bluish green, slightly irrorated with white scales. Forewings with proximally white, distally black spot at ½ of the inner margin. Fore- and hindwings with black, whitish encircled, discal dot, terminal dots absent. Hindwing termen angled at M3. Length of male palpi 1.0 – 1.2 times diameter of eye, tip and upperside green, underside white. Frons green. Antennae bipectinate in male, antennal branches pale ochre. Male frenulum present. Male hindtibia with white pencil, four spurs and terminal process covering 1/3 of the first tarsomere.

Male genitalia ( Fig. 60 ). Uncus short, dilated at base. Socii developed, narrow, length about 1/3 length of uncus. Saccus round. Valva broad, subapical ventral lobe conspicuous. A slerotized spinose process (harpe) arising from central part of valve basis, directed toward apex. Sacculus narrow, membranous at base, sclerotized towards tip. Aedeagus long (2.5 mm), with a stout, long, curved cornutus and another shorter one, vesica with a bundle of microspinules. Sternum A8 with two tapering projections, deeply concave between.

Genetic data. From Ethiopia, so far, only sequenced to a 164bp short fragment ( BC ZSM Lep 85807). Nearest neighbour in Ethiopia: P. septentrionalis sp. n. (4.4%). The short fragment of Ethiopian P. corrugata is genetically identic with that of the holotype of P. permagna Herbulot, 1982 from Cameroon. This result needs to be further analyzed with full fragments. Genitalia of both species are clearly different, however.

Remarks. Well matching genitalia of the holotype specimen in NHM, but in the holotype the projections on sternum A8 are shorter. Strongly differing from P. f u s ca sp. n. in male genitalia, see there. The spinose process arising from the centrobasal part of valva possibly homologous to the equivalent in P. beryllaria sp. n.
