Catoptria kasyi Błeszyński, 1960

( Figs 17, 18 , 37 , 55 )

Catoptria kasyi Błeszyński, 1960 . Type locality: [North] Macedonia, Peristeri M [ou]nt[ain]s. Lectotype: Golemo ezero, 2200 m, 25.vii-5.viii.1959, F. Kasy, GS 9016 Wien (1171 BL), NHMW, examined.

Material examined: North Macedonia: 1 male paratype, 22.VII-5.VIII.1959, Peristeri Mons, Golemo Ezero, 2200 m, Maced. Occ., F. Kasy, GS 5123 GB, SNSB ; 3 males, 1 female, N. P. Perister, Golemo Ezero, 31.vii.2015, I. Richter legit, GS 6952 and 6982 GB, RCIR and RCGB .

Diagnosis: The habitus ( Fig. 17 ) of the male is hardly distinguishable from closely related species; however, C. kasyi has white head and tegula and is paler in ground colour than C. korab sp. nov. ( Fig. 22 ) and C. sarplanina sp. nov. ( Figs 19, 20 ), with forewing veins well marked with off-white, larger terminal dots, and an off-white hindwing, in contrast to C. korab sp. nov., which has an off-white hindwing suffused with yellow-brown, and C. sarplanina sp. nov., which has a brown hindwing suffused with yellow. The female ( Fig. 18 ) is unmistakable due to its strongly reduced wings, to the extent that it is probably incapable of flight. The male genitalia ( Fig. 37 ) differ from those of C. korab sp. nov. ( Fig. 38 ), C. plat sp. nov. ( Fig. 40 ), and C. sarplanina sp. nov. ( Fig. 39 ) in that the pars basalis is apically stouter and has an almost straight edge basally, with a moderately rounded apex; medially, the arm is larger than in similar species except for C. plat sp. nov. with a width/length ratio of 0.3, and finally, its concavity is less evident than in C. korab sp. nov. and C. sarplanina sp. nov. but more evident than in C. plat sp. nov. The female genitalia ( Fig. 55 ) differ from those of C. sarplanina sp. nov. ( Fig. 56 ) in that the sterigma is strongly bilobed posteriorly and the ostium bursae is smaller. The female genitalia of C. domaviellus ( Fig. 54 ) have the sterigma poorly bilobed and the ductus bursae is less sclerotized than in C. kasyi .

Description of female genitalia: Papillae anales subtriangular, with sclerotized section narrowing dorsally. Apophyses posteriores subtriangular. Apophyses anteriores poorly produced. Abdominal segment VIII ring-shaped, with sternite less sclerotized. Ostium bursae rounded, with lamella postvaginalis strongly bilobed. Ductus bursae 1.3 as long as corpus bursae, sclerotized and wrinkled up 2/3 its length, then delicately wrinkled and scobinate. Corpus bursae suboval, scobinate, with a spherical signum.

Distribution: North Macedonia (see Remarks).

Remarks: The female genitalia figured by Błeszyński (1965: Pl. 117, Fig. 233) belong to an unknown species. We could trace this specimen in NHMW, but it is in poor condition and therefore is hardly attributable to the species discussed here. Its labels are from Pashtrik mountain in Albania, which is quite close to the locus typicus of C. nikai and especially to that of C. sarplanina , but its habitus is very different in the forewing decidedly less slender than in C. nikai and in the lighter colour than in C. sarplanina . It is probably referable to another new species, not described here due to the lack of additional material.
