Diagnosis. Ennada pellicata is distinguished from the other species of the genus by: V-shaped lamella antevaginalis; subrectangular juxta with two elongate projections on the posterior and lateral margins; hindwing of the male with apex projected.
Redescription. Male (Figs. 3–5). Head with filiform antennae: vertex dark brown; front light brown; palpus reddish brown in apically and light brown to yellowish basally. Thorax light brown dorsally; patagium light brown; tegula light brown, with posterior tuft; ventral surface of the thorax with yellowish hair like scales. Legs, dark brown, tibial formula 0-2-4. Forewings, wide and triangular, dorsal surface dark brown in basal 2/3, distal third ivory; forewing apex with a brown triangular blotch; ventral surface of the forewings yellow, darker basally. Hind wing with apex projected; dorsal surface ivory, darker in the internal edge ventral surface of the fore and hind wings are velvety, similar to the dorsum; ventral surface, yellow darker basally. Abdomen light brown, with tuft on lateral margins; final abdominal segment with tuft of light brown scales on posterior margin, approximately half the size of the length of the last segment. Male genitalia (Figs. 12, 14). Uncus hook-like, 3/4 the length of the valvae; sub-quadrangular valvae, with two tufts of long setae (androconia) at base of costa setae thin dorsally, coarse ventrally; sacculus semicircular; juxta subrectangular with two elongate projections on the posterior, lateral margin. Aedeagus simple, tubular; aedeagus sheath curved in its posterior third; cornuti with a row of short, conic thorns reach almost half length of the aedeagus. Female (Figs. 4–6). Head similar to the male. Thorax dark brown in the dorsal surface; patagium dark brown; tegula light brown, ventral surface of the thorax light brown. Legs similar to the male. Wings similar to the male, but apical projections absent in hindwing. Abdomen light brown, without posterior tuft. Female genitalia (Fig. 13). Lamella antevaginalis in form of a "V", sclerotized basally; corpus bursae globose and membranous; coniform signum with a wide base, 1/7 the length of the corpus bursae; ductus bursae tubular; posterior apophyses twice length than the anteriores.
Distribution. Ennada pellicata is distributed between 33º and 43º S, between the provinces of Santiago and Palena (Fig. 18).
Host plants. Aextoxicon punctatum R. et P. (Aextoxicaceae) (Bocaz 2001).
Remarks. In some male and female specimens, the postmedial band has an extrusion between the medial veins, which reaches the subterminal band (Figs. 5, 6). The mesoscutellum of some specimens has two short tufts that extended laterally, reaching the abdomen.
