Diagnosis. Ennada flavaria is distinguished from the other species of the genus by: presence of a jugum in the anal margin of the male forewings positioned above the hind wings; uncus in the form of an acute hook; apex of the valvae with 2 thorny-like processes; sub-rectangular juxta; lamella antevaginalis consisting of a quadrangular middle area and two sub-triangular lateral areas.

Redescription. Male ( Fig. 1 ). Head with pectinate antennae; light-brown vertex; dark brown front; labial palpus, light-brown near the base and reddened brown near the apex. Thorax, light-brown on dorsal surface; patagium dark brown; tegula light-brown with hair-like scales posteriorly. Ventral surface of the thorax yellow. Hind and middle legs dark brown basally, with corresponding tibia and tarsus light brown; fore femur clear brown, fore tibia and fore tarsus dark brown; tibial formula 0-2-4. Broad, triangular forewings with a jugum in the anal margin positioned above the hind wing; dorsal surface of the forewings grayish, shiny with 2/3 basal section dark brown, distal third paler: apical tip with a dark brown triangular blotch; with a light brown basal strip; sub-terminal band represented by a row of dark brown points. Dorsal surface of the posterior wings with a series of short bands between the medial veins and the posterior margin. Ventral surface of the fore and hind wings grayish, shiny, similar pattern to dorsum. Abdomen light brown dorsally, with posterior tuft, approximately the same length as the last segment. Male genitalia ( Figs. 9, 11 ). Uncus hook-like, sclerotized, narrow, apically acute, length is sub-equal to the length of the valvae; triangular valvae, broader apically, length twice greatest width; costal margin of the valvae with tufts of thick setae (androconia) medially; apex of valvae with two thorn-shaped processes, gnathos absent; juxta sub-rectangular; sacculus sub-quadrangular. Aedeagus tubular, sinuate, posterior third curved; vesical cornuti formed by a set of short, thick spines, 1/4 length of the aedeagus. Female ( Fig. 2 ). Head with simple, filiform antennae; vertex and front reddish brown; labial palp reddish brown apically and light brown to whitish basally. Thorax dark brown dorsally; patagium with dark to reddish brown scales: tegulae with dark brown scales, with hair-like scales posteriorly; elongated mesoscutellum, with 2 tufts of short scales on posterior margin, directed posteriorly; ventral surface of thorax with light brown to yellow scales. Legs reddish brown, tibial formula 0-2-4. Broad, triangular forewings; brown dorsal surface, dark brown in the 2/3 basal section; marginal area with 3 rows of black spots; brown-gray interior border. Light brown hind wings, becoming dark brown distally. Light brown abdomen with a small tuft on posterior segments, approximately 1/3 of the length of the last abdominal segment. Female genitalia ( Fig. 10 ). Strongly sclerotized lamella antevaginalis, composed of three areas: a quadrangular center, and two sub-triangular lateral areas with irregularly wavy margins; globose corpus bursae; strongly sclerotized coniform signum, 1/3 the length of the corpus bursae; tubular, membranous ductus bursae, slightly sclerotized basally; posterior apophyses three times longer than anterior ones.

Distribution. Ennada flavaria can be found between 29º and 44º S, between the provinces of Coquimbo and Chile ( Fig. 18 ).

Host plants. Myrceugenia obtusa (DC) Berg ( Myrtaceae ) ( Bocaz 2001).

Remarks. In some female specimens, a transverse white line with black dots after the subterminal band was present on the anterior wings.
