Diagnosis. Indalia lutarella luqueti was described from the French Department of Savoie. It is characterized by the reduction of the grey-blackish area of the anterior half of the hindwing, the black shading limited to the costal area and neighbouring veins, on both upperside and underside.

Re-description. Imago ( Figs. 27–28 View FIGURES 25–32 ). Average wingspan males 26.9 mm (n=10; 24–30 mm); average wingspan females 21.2 mm (n=10; 19–24 mm).

Genitalia ( Fig. 62 View FIGURE 62 ). No significant differences in relation to the nominotypical subspecies.

Immature stages ( Fig. 86 View FIGURE 86 ). The last instar larva is 11–14 mm long. Cephalic capsule totally black. Body with grey verrucae (wart L1 has not been observed) and a black, narrow and sinuous dorsal line; there is also an irregular black spot surrounding SD 1 and touching wart D2, another smaller next to L2 and another below wart L3. Pupa light brown, tip of abdomen rounded, without cremaster. Pupa of female has a characteristic depression dorsally on the metathorax, causing the abdomen to bulge; in males, this depression is very smooth. Cocoon woven between lichens.

Molecular data. All specimens analysed in the present work have been identified as Indalia lutarella luqueti and cluster together in a strongly supported species clade (PP=1, n=9) and an extremely low within-group distance (TN-dist = 0.07% ±0.05SE). RESL Cluster Analysis returned a single cluster and all sequences matched the only BIN defined for Indalia lutarella (BOLD: ABZ2872).

Biology. The biology does not differ from that of nominotypical Indalia lutarella .The larvae feed on lichens, in captivity they accept artificial diet.

Distribution ( Fig. 108 View FIGURES 95–109 ). This subspecies is known from northwest of the French Alps (Savoie), the eastern and western Pyrenees and from other northern Spanish localities on the Cantabrian coast and Galicia. Also known in isolated and scattered colonies throughout Spain. The citation from in Portugal is very doubtful.
