Diagnosis. Nyea lurideola can be confused with Manulea complana , Manulea iberica , Manulea pseudocomplana and Manulea costalis , but is distinguished by the yellowish costal stripe which ends in a point just before the apex, while in Manulea complana , Manulea pseudocomplana and Manulea costalis it extends to the very tip of the wing. In Nyea lurideola , the wings are relatively shorter, but distally more dilated and apically more rounded than in Manulea complana , Manulea iberica , Manulea pseudocomplana and Manulea costalis .

Re-description. Imago ( Figs. 35–36 ). Average wingspan males 33.7 mm (n=10; 29–37 mm); average wingspan females 31.4 mm (n=10; 27–35 mm).

Genitalia ( Fig. 66 ). Male and female genitalia: See the description that has been given for the genus Nyea .

Immature stages ( Fig. 88 ). The final instar larva is 20 to 22 mm long. Cephalic capsule totally black. On the body, the verrucae D1, D2 and SD 1 are black, the verrucae L2 and L3 are grey (the L1 wart has not been observed); all these verrucae have black and translucent setae; body dark dorsally, with mixed black and blue spots and with one orange broad line between segments 1 to 8. Pupa stylized, glossy brown, smooth, with well-marked circular depressions on the back of the metathorax and abdominal segments 1 to 8; tip of abdomen rounded, without cremaster. Pupa very similar in both sexes. The cocoon woven among lichens.

Molecular data. With a low within-species TN-dist of 0.26% ± 0.12SE, RESL cluster analysis for Nyea lurideola sequences reveals a cluster that matches the single BIN defined for Nyea lurideola (BOLD: AAB6833).

Biology. Univoltine, with a long flight period from July to September–October. Frequent in humid mountain biotopes, mainly coniferous forests and meadows, at elevations between 500 and 2000–2500 m. Adults visit flowers in late afternoon, and both sexes come to artificial light at night. The larvae feed mainly on algae and lichens, although they also feed on plant species belonging to the genera Sarothamnus, Rumex , Rubus and Vaccinium . In captivity they accept leaves of Salix , Rubus and Taraxacum ( Ylla et al. 2010) and artificial diet.

Distribution ( Fig. 112 ). Eurasian. Present throughout Europe except the northernmost parts of the Scandinavian countries. In the Iberian Peninsula, it is present in northern localities and more dispersed in the central part, although there are few reports from Portugal.
