Diagnosis.

Imago. Forewings narrow with nearly straight costal margin and a pale subcostal line; externally resembles many other groups of Eilema sensu lato.

Male genitalia. Uncus of medium size, robust, sclerotised and with the apical end in the form of a small hook; tegumen triangular, relatively short compared to uncus; valvae very wide and rounded, with the costa strongly convex; slightly sclerotised sacculus with a long saccular process in the form of a long hook covered with bristles contacting the valvae; clasper absent; juxta without apical processes; vinculum very small, semicircular; aedeagus wide and extremely short, without apical sclerotised fascia with two large highly sclerotised cornuti; short vesica in the form of a bag.

Female genitalia. A nal papillae moderately sclerotised with short processes; 8th segment wide with anterior processes shorter than posterior ones; lamella postvaginalis cup-shaped, large and strongly sclerotised; ostium bursae small and slightly sclerotised; ductus bursae very small and arched; bursa copulatrix ovoid, almost spherical, membranous, with a signum near the base. At the top of the bursa, there is a rectangular process on the left side with the base covered with small spines; on the opposite side, the bursa has a large globular process or membranous wart that could be confused with a second bursa, from which the ductus seminalis arises.

Molecular data. The Nyea genus constitutes a strongly supported clade (BI=1). Despite the strong morphological differences, this species consistently groups with Indalia marcida and Indalia predotate from the genus Indalia . However, Nyea also presents similar genetic distances to the lutarella Group ( Table 2 and Table 3). In any case, this genus shows a considerable COI distance from the Eilema (TN-dist=8.96%) and Manulea (average TN-dist=7.63) genera.
