Sattleria haemusi Huemer , sp. nov.

Type material. Holotype ♂, ‘SW Bulgaria, Rila Mts. Granchar Circus 2200 m N42°07´16´´ E23°35´28´´ 27.08.2009, at light leg. B. Zlatkov & Y. Mutafchiev’ ‘GU 13/1356 ♂ P. Huemer’ ‘ BC TLMF Lep 08944’ ( FBBZ).

Paratype. Macedonia: 1 ♂, Tetovo, Povoa Sapka, Felskar, W Tetovo, 2130 m, 7.8.2012, leg. C. Wieser, gen. slide GU 13/1360 ♂ P. Huemer DNA barcode id KML Lep 0 0 484 (LMK).

Description. Adult ( Fig. 4 ). Male. Head brown with cream-coloured face; labial palpus cream, mottled brown; antenna dark brown, scapus and flagellum covered with cream scales on lower surface; thorax and tegula brown. Wingspan 16.0–17.0 mm; forewing light brown with extended dark brown and whitish mottling, whitish costal and tornal spots ill defined; costa from base to terminal area dark brown; fold with two oblique black-brown spots, separated by light brown, a dot-shaped black spot at 1/2 and an ill-defined angulated spot at 3/5; termen with some black scales, fringes concolorous with ground colour, fringe line present; hindwing light grey brown with concolorous fringes. Forelegs and middle legs brown with white scales, hindlegs white with long white bristles.

The colour and wing markings may differ slightly in fresh specimens as the type-material is rather worn.

Female unknown.

Male genitalia ( Figs 11 , 19 ). Uncus with rounded apex, culcitula moderately large, gnathos a large hook; tegumen anteriorly widened, broadly and deeply emarginated anterior margin; pedunculi long, slender; valva long, slender, extending almost to apex of uncus, distally slightly inflated with pointed tip and long apical setae; sacculus slender, hardly inflated, with acute apex; primary process of vinculum long, moderately broad, needle shaped, about level with sacculus; secondary process of vinculum fused with primary process, extending from base to about 2/5 of primary process, broadly arched, sub-oval with outer margins slightly serrate; saccus long, moderately slender; phallus moderately long and slender, straight, without medial projection, coecum weakly inflated with two minute basal sclerites, apex with small hooklet.

Female genitalia. Unknown.

Diagnosis. Sattleria haemusi is externally very similar to other strictly allopatric species of the genus with a divided basal streak of the forewing, i.e., S. melaleucella and S. dzieduszyckii , but is smaller than the former and with more distinct black-brown markings on the forewings compared to the latter. Dissection of genitalia is necessary for safe identification. The male genitalia closely match those of S. dinarica ( Figs 9 , 17 ), S. triglavica ( Figs 10 , 18 ) and S. dzieduszyckii ( Figs 12 , 20 ), but differ by the evenly curved sub-oval shape of the secondary process of the vinculum, from the former two also by the broader primary process with stronger setae.

Molecular data ( Fig. 21 ). The intraspecific divergence of the barcode region is low with 0.15% (p-dist) (n=2). The distance to the nearest neighbour S. cottiella is 3.69% (p-dist) (n=5).

Bionomics. Host-plants and early stages are unknown. The few adults known to date have been collected in August at light at elevations of about 2100 to 2200 m.

Distribution. Known with certainty only from the Rila Mts. ( Bulgaria) and the Šar Planina Mts. ( Macedonia), but from biogeographical considerations, unverified records from Albania ( Povolný 2001) probably also refer to this species.

Etymology. The name is derived from the latin noun haemus = Balkans, referring to the distribution of the species.
