Isturgia limbaria anzascaria (Staudinger, 1892)
Fidonia limbaria var. anzascaria Staudinger, 1892, Dt. ent. Z. Iris 5: 198, [Italy, northern Piedmont]: Val d’Anzasca near Macugnaga.
Material examined.
Italy: 1 ♂, Piedmont: Monte Rosa, Macugnaga, near Pecetto, 1400 m, 21.vii.1984, C. Flamigni leg. (RCCF). 1 ♂ 1 ♀, Piedmont: Monte Rosa, Macugnaga, under Alpe Bill, 1400-1600 m, 26.vii.1984, C. Flamigni leg. (RCCF).
Diagnosis
(Figs 5 View Figures 3–12 , 10 View Figures 3–12 , 15 View Figures 13–17 , 20 View Figures 18–22 ). Large, light yellow. Forewing upperside almost free of dark scales (except the costa and the terminal fascia), hindwing upperside with a few dark scales. Forewing dark terminal fascia narrow in the male and reduced to a few blackish dots in the female according to the original description; this fascia is present in both sexes in our specimens, but it is relatively narrow in relation to their size. Hindwing dark terminal fascia rather narrow or reduced to a few scales, especially in the female. Hindwing underside yellow, scattered with a few dark vertical stripes; whitish radiating streaks present but not very evident. Although Prout (1915) and Wehrli (1940) reported also the ssp. rablensis from Macugnaga, our specimens from this locality correspond well with the description of Staudinger, differing from rablensis by the larger size (wingspan 27-30 mm in anzascaria , 23-26 mm in the Italian specimens of rablensis ) and by the purest yellow, almost without dark scales; it will be possible to definitively confirm the validity of the subspecies examining a greater number of specimens.
In the only female examined signum large (1.4 mm). Bullae tympani without roundish lobe.
Distribution.
Valle Anzasca (Italy: northern Piedmont), on the southern side of the Monte Rosa massif (Fig. 2 View Figure 2 ).
Remarks.
Not yet barcoded. The size of the signum and the absence of a roundish lobe in the bullae tympani indicate a greater similarity with rablensis and roraria , but the wing upperside is closer to delimbaria , but the hindwing has a dark terminal fascia.
