Isturgia limbaria rablensis (Zeller, 1868)
Fidonia limbaria var. rablensis Zeller, 1868, Verh. zool.-bot. Ges. Wien 18: 587, [Italy, Friuli-Venezia Giulia]: Grafenlahn above Raibl [Cave del Predil] and below along the stream. At the time the locality Raibl was situated in Austria (Upper Carinthia).
Fidonia limbaria styriaca Schwingenschuss, 1911, Verh. zool.-bot. Ges. Wien 61 (1/2): (46), [Austria], Styria: Polster, near Prebichl [ Präbichl], 1400-1600 m. Synonymy follows Huemer and Tarmann (1993). Also Huemer (2013) attributes the population of Styria to the taxon rablensis .

The underside of a male from Gitschtal (Austria: Carinthia) is figured by Wieser (2008: fig. 16); colour images of specimens from Serbia (as I. limbaria and as I. roraria ) are shown on the website Alciphron ( 2019).
Diagnosis
(Figs 6 View Figures 3–12 , 11 View Figures 3–12 , 16 View Figures 13–17 , 21 View Figures 18–22 ). Upperside more or less scattered with groups of dark scales (or dark lines short or longer), scattered or more dense; in some specimens (mainly in the westernmost part of the distribution area) there are only a few dark scales in the forewing (except on the costa and in the terminal fascia), a little more dense in the hindwing; in other specimens (also among the most western ones) both wings are scattered with dense groups of dark scales; dark terminal fascia generally narrow, wider in Bulgarian specimens, in the hindwing it can be present or absent. Underside with fore- and hindwings more or less different in pattern and colour (identical in roraria s. str.): both wings scattered with dark vertical lines, but colour generally more orange-yellow in the forewing, more whitish yellow in the hindwing, whitish radiating streak(s) of the hindwing present (sometimes barely perceptible).
In the female genitalia signum large (1.1 mm, exceptionally 1.6 mm). Bullae tympani without roundish lobe.
Distribution.
Northern Italy (see Fig. 2 View Figure 2 ), Austria (Huemer, 2013: Carinthia, Styria), Slovenia, Serbia, Macedonia, Kosovo, Albania, Greece (Western Macedonia), Bulgaria, Romania. The taxon rablensis was recorded from Albania (Djalica e Lumës) by Rebel and Zerny (1934) and by Povolný and Moucha (1957: fig. 57); the first two authors also mention Žljeb in Kosovo; its occurrence in Romania is confirmed from the Bucegi Mountains (see also Popescu-Gorj (1995)) and the Nemira Mountains; the records of I. roraria s.l. from other areas of Romania (in particular from the Cluj-Napoca area: cf. Rákosy et al. (2016)) must be verified by examining the underside of the specimens. The species also occurs in Croatia and Bosnia and Herzegovina ( Skou and Sihvonen 2015), but we have not examined material from these countries. Viidalepp (1996) attributes the populations from Transcaucasus (Georgia) to this subspecies (as I. roraria rablensis ).
Molecular data.
The westernmost populations (Lombardy and Monte Baldo in Italy, Carinthia in Austria) correspond to a separate BIN, at a distance of 2.0%, while all the others (from the Julians Alps to Bulgaria and Romania) share the same BIN of the following subspecies; however, no constant morphological character corresponds to these genetic differences and it is not possible to distinguish the specimens of the more western regions from those of the Julian Alps (both populations are very variable). The exact border between these two BINs is not known, since no specimens from the Carnic Prealps have been barcoded. Three specimens from Romania diverge into a separate cluster, but they are morphologically very similar to those from Bulgaria.
