Diagnosis
(Figs 4 View Figures 3–12 , 9 View Figures 3–12 , 14 View Figures 13–17 , 19 View Figures 18–22 ): Forewing almost free of dark scales (except the costa and the terminal fascia). Hindwing with more dark scales than forewing, but lighter than in most specimens of the nominate subspecies. The dark terminal fascia is generally narrow in the forewing (wide in the form pedemontaria ), absent or very reduced in the hindwing (also in the form pedemontaria ). The underside is variable, but less contrasted and less sprinkled with black than in most specimens of the nominate subspecies. The taxon pedemontaria (Figs 4b View Figures 3–12 , 14b View Figures 13–17 ) is an individual form, sometimes prevalent in some places: it shows a wide, dark terminal fascia on the forewing and a weakly marked underside on the hindwing, which is orange-yellow, scattered with dark vertical stripes, with barely perceptible lighter radiating streaks.
In the female genitalia signum small (0.8-0.9 mm, exceptionally 1.2 mm in a female from the Apennines near Bologna: see Table 3 View Table 3 ). Bullae tympani with a roundish lobe (absent in a female from the same locality: see Table 3 View Table 3 ). The specimens from northern Piedmont (Graian and Pennine Alps) were not dissected.
Distribution.
France SE, Italy (Piedmont, Liguria, Tuscany, Emilia-Romagna: see Fig. 2 View Figure 2 ). According to Leraut (2009) its distribution in France is limited to the southern Alps; we have confirmation for the following departments: Drôme: Montagne de Chamouse ( Skou and Sihvonen 2015: pl. 2, fig. 18c, e), Vaucluse, Alpes-de-Haute-Provence, Alpes-Maritimes, Var. In Piedmont it occurs mainly in the south, from the Maritime Alps to the Apennines; according to Flamigni et al. (2007) it occurs also further north, up to the Graian Alps and the surroundings of Biella (Pennine Alps); the specimens from the Biella area were examined (without dissection of the genitalia) by the first author during the preparatory work on the first volume on the Italian Ennominae . The geographic position would suggest that specimens from Corsica also belong to this subspecies: this will need to be verified through the examination of the collected material.
Molecular data.
The two barcoded specimens (both from Italy) diverge from those of the taxon limbaria s. str. (from Germany and Upper Normandy) respectively by 1.2% (Ligurian Alps) and 1.6% (northern Apennines); however, they diverge from one another by 1.6% and cannot be regarded as a "common separate cluster".
Remarks.
The distribution of the taxa delimbaria and rablensis in the northern Piedmont is similar to that of Crocota pseudotinctaria Leraut, 1999 and C. tinctaria ( Hübner, 1799): delimbaria and pseudotinctaria occur in the surroundings of Biella, while rablensis and both pseudotinctaria and tinctaria occur further to the north-east, in Campello Monti ( tinctaria also occurs in Lombardy, like rablensis ). The analysis of the DNA of the northern Piedmontese populations could help to better understand the relationship between the three taxa present in this area ( delimbaria , anzascaria , rablensis ); the barcoding of a specimen from Campello Monti was unfortunately not successful.
