Sattleria dinarica Huemer View in CoL , sp. nov.

Type material. Holotype ♂, ‘Yu. Crna Gora Durmitor Vel. Kalica, 190 26.vii 1985. Jakšic P. leg. [in capital letters]’ ‘GEL 323 ♂ P. Huemer’ ‘ Sattleria triglavica Pov. det. P. Huemer, 2003’ ‘Photographed for Microlep. of Europe vo. 6, 2010’ ( TLMF).

Paratypes. Montenegro: 4 ♂, same data as holotype, one with gen. slide GEL 1129 P. Huemer, BC TLMF Lep 0 3093 (658 bp), BC TLMF Lep 3094 (307 bp), BC TLMF Lep 0 1442 (0 bp).

Description. Adult ( Fig. 3 View FIGURES 1 – 4 ). Male. Head cream coloured, anteriolateral part brown; labial palpus whitish cream with base of second segment and third segment mottled brown; antenna dark brown, scapus and flagellum covered with cream scales on lower surface; thorax and tegula light brown. Wingspan 18.0–20.0 mm; forewing light brown, with dark brown transverse mottling at 3/4, extended longitudinal whitish area in middle of wing and in terminal area without distinct costal and tornal spots; costa from base to terminal area dark brown; fold with oblique blackbrown line well defined, a dot-shaped black spot at 1/2 and an angulated one at 3/5; termen with distinct black dots, fringes concolorous with ground colour, well-defined fringe line present; hindwing light grey brown with concolorous fringes. Forelegs and middle legs brown with white scales, hindlegs white with long white bristles.

Female unknown.

Male genitalia ( Figs 9 View FIGURES 9 – 12 , 17 View FIGURES 17 – 20 ). Uncus with weakly 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 with weakly inflated basal part, distally slender; primary process of vinculum long, needle shaped, about level with sacculus; secondary process of vinculum fused with primary process, extending from base almost to middle of primary process, broadly sub-oval with outer margins nearly at right angle; saccus moderately long, evenly tapered; 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 dinarica is externally very similar to several strictly allopatric species of the genus with a basal streak on the forewing (i.e., S. basistrigella , S. triglavica , S. styriaca and particularly S. dolomitica ) and dissection of genitalia is necessary for safe identification. The male genitalia closely match those of S. triglavica ( Figs 10 View FIGURES 9 – 12 , 18 View FIGURES 17 – 20 ) but differ by the nearly sub-rectangular outer shape of the secondary process of the vinculum, a character that as far as known underlies no individual variation. The secondary process of the vinculum is also more evenly convex in S. haemusi and S. dzieduszyckii ( Figs 11–12 View FIGURES 9 – 12 , 19–20 View FIGURES 17 – 20 ); S. haemusi also differs by strong setae on the primary process, and S. dzieduszyckii by the evenly constricted shape of the sacculus. Also, S. dzieduszyckii differs from all mentioned taxa by the submedial process of the phallus.

Molecular data ( Fig. 21 View FIGURE 21 ). The intraspecific divergence of the barcode is unknown (n=1). The distance to the nearest neighbour S. breviramus is 3.86% (p-dist) (n=5). The morphologically similar S. triglavica differs in the barcode by 5.43% (p-dist) (n=1, 540 bp—based on a historical sample).

Bionomics. Host-plants and early stages are unknown. The few adults known to date have been collected in late July at light. The habitat is alpine scree on limestone with sparse vegetation at an elevation of about 1900 m.

Distribution. Only known from the type-locality in the Durmitor National Park ( Montenegro). Published records of Sattleria from this area all refer to the new species (Povolný 1986, Huemer & Jakšic 1996).

Etymology. The name refers to the distribution area, the Dinaric Alps, and is derived from the latinized adjective dinarica .

Remarks. Populations of Sattleria dinarica from Montenegro were initially subsumed in the description of S. dzieduszyckii ssp. triglavica by Povolný (1986), a taxon that was later erected to species level ( Pitkin & Sattler 1991) and that is geographically restricted to the Julian Alps ( Slovenia).

S. triglavica View in CoL as figured in Huemer & Karsholt (2010) is a mixture of two other species. The adult figure 208a depicts the holotype of S. dinarica View in CoL , figs 208b-c belong to S. basistrigella View in CoL , which was recently raised from subspecies to species level ( Huemer & Hebert 2011). Similarly, the male genitalia in fig. 208 are misidentified and depict S. dinarica View in CoL whereas male genitalia (fig. 208a) and female genitalia (fig. 208) belong to S. basistrigella View in CoL .
