to NABOKOV and studied by him obviously represents this new taxon (cf. NABOKOV 1945, PI. 2, FAG). Etymology - a noun, gender feminine, from the Spanish "cuzquena", meaning an inhabitant of Cuzco, the geographical area in which some of the paratypes were collected. Table 4. Male genital diagnostic characters of the taxa N. faga, N. ada and N. cuzquenha N. faga N. ada N. cuzquenha Valval shape wide, costa convex narrow and long, not so wide, (Figs 39-40) not convex longer with slightly convex costa Aedeagus suprazonal portion suprazonal and suprazonal portion (Figs 41-42) shorter than subzonal subzonal portions equal shorter than subzonal, portion, apex stout in length, apex pointed apex slightly pointed Itylos mashenka (BÁLINT, 1993), comb. n. (Itylos genus-group) Figures - male genital structures: 43-45. Description of male genitalia - Uncus strong but short (1/3 valval length), gnathos shorter than uncus and* broken in right angle at half length with large and widened basal part, juxta V-shaped with very long and relatively strong arms; valval shape rounded with strongly developed and pointed costal process, anal process shorter but heavily sclerotized and bristled quadrant apex; aedeagus long with short and pointed suprazonal element (1/5 length of subzonal). Material examined - 1 male, labelled as "Peru, Rio Rímac, Bellavista, 4000 m, 7.VII. 1974, G. Lamas", deposited in MUSM. Genital dissection (gen. prep. no. Bálint): 578. Remarks - The male genital structures obviously show that the taxon was described as Madeleinea (the holotype has no abdomen) by mistake and it has to be transferred to the genus Itylos DRAUDT, 1921. Therefore, we present here Itylos mashenka (BÁLINT, 1993) as comb. n. As was pointed out by BÁLINT & JOHNSON (1994b), the male genitalia of all known Itylos species is unique. The taxon mashenka repeats this situation with characters, like the aedeagus with very long subzonal and short but bulbous suprazonal portions (see BÁLINT & JOHNSON 1994b: figs 34-57). The female genital structure of Eldoradina cyanea BALLETTO, 1993 (Cyclargus genus-group) Figures - Wings: 17-18, female genital henia: 33, tergal morphology: 28.
