Diagnosis. Ennada blanchardi  is distinguished from the other two species of the genus by the larger size and orange brown color of the wings of the both sexes; in the male genitalia by an elongated, apically truncated, compressed uncus; and in the female genitalia by the lamella antevaginalis in the form of an inverted cone.

Description. Male ( Fig. 7View FIGURES 1 – 8). Head with pectinate antennae; vertex and front with whitened scales and orange markings, labial palpus with a red apex and white base. Thorax light brown scales with red markings on dorsum, similar to patagium and tegula; tegula with hair-like scales elongated posteriorly. Thorax venter with yellow and reddened scales. Forewings wide and triangular, clearer than the female ones; dorsum light brown to orange; medial area, dark brown; basal area, grayish brown; forewing venter orangish brown, darker basally. Hind wings light brown, with orange fringe from the center until the interior edge. Venter of wing orange, becoming darker areas proximally. Abdomen light brown anteriorly and reddish brown posteriorly; tuft on posterior abdominal segments, approximately half of the length of the last abdominal segment. Male genitalia ( Figs. 15, 17View FIGURES 15 – 17). Uncus elongated, apically truncate; valvae becoming broader apically, sclerotized costa, apically hooked and with two tufts (androconia) medially; gnathos absent; juxta sub-rhomboid; sacculus quadrangular anteriorly and triangular posteriorly. Aedeagus simple, concave in the anterior third at ductus ejaculatorius; cornuti a set of short spines, 1 / 4 of the length of aedeagus. Female ( Fig. 8View FIGURES 1 – 8). Head with simple, filiform antennae; vertex and front with whitened scales with orange markings, labial palpus with reddish apex and the whitish base. Thorax with light brown scales with reddish markings on its dorsal surface as well as on the patagium and tegula, patagium and tegula with hair-like scales extending posteriorly. Thorax ventrally with yellowish and reddish scales. Forewings and hindwings similar to those the male. Abdomen light brown anteriorly, with reddish brown scales posteriorly, with tuft on posterior abdominal segments, approximately half the length of the last abdominal segment. Female genitalia ( Fig. 16View FIGURES 15 – 17). Corpus bursae globular; signum coniform, strongly sclerotized, 1 / 7 length of the corpus bursae; ductus bursae membranous, 1 / 16 length of the corpus bursae; lamella antevaginalis in the form of an inverted cone, apophyses twice lenght of anteriores.
