Diagnosis. Hoplosauris granitata can be distinguished from the other species of the genus by the: vesicle with a tuft of hairy scales extended towards the abdomen in the male hindwings; three long and thick bristles in the medial area of the valvae; corpus bursae with microspines distributed in centrally, spreading left. These three characters are the autapomorphies for the species.

Redescription. Male ( Figure 1e). Head: Antennae sub-apically thickened, covered by white and dark brown scales. Frons and vertex with white and dark brown scales. Labial palpi brown at base, becoming white apically. Thorax: dark brown with whitish spots. Patagia and tegula with similar colour pattern. Tegula with piliform scales, extending posteriorly. Forewings: upperside dark brown, basal line grey, surrounded by dark brown scales. Medial line the same color as basal line. Postmedial line with orange circles. Terminal line represented by dark brown semicircles. Discal mark dark brown. Underside 2/3 basal shining brown, apical third shiny whitish. Hindwings: vesicle concave, hairy with tuft of scales on the internal margin; tuft half the length of the hindwings, on the proximal margin projected posteriorly; dorsal surface whitish, ventral surface whitish; discal cell, dark brown. Abdomen covered mainly by white scales with some brown scales intercalated. Fore and mid legs with dark brown and white intercalated stripes. Hind legs white. Female. Similar to the male. Hindwing vesicle absent. Male genitalia ( Figures 7a, c). Uncus curved, hairy, with acute apex, ½ the length of the valvae. Valvae subrectangular. Androconia on the subapical region of the valvae. Three long and thick bristles are present directly ventral of the androconia. Semicircular saccus. Costa slightly sclerotized. Ventral margin of the valvae with neckline on its subapical region. Tubular aedeagus. Vesical cornuti formed by two groups of long and fine spines of subequal size, ¼ the total length of the aedeagus. Female genitalia ( Figure 7b). Sterigma membranous. Corpus bursae sclerotized and elongated, striated on its anterior half, posterior half membranous; with microspines on internal surface, distributed on its central and spreading circularly towards left area. Anterior apophyses approximately half length posteriors apophyses. Ductus bursae ¼ the length of corpus bursae. Ductus seminalis discrete.

Distribution. This species is distributed betewen 34ºS and 40ºS in the provinces of Melipilla and Valdivia ( Chile), and the province of Neuquén, Argentina.

Flight period. Specimens were captured during the months of August and October. There are no records from other months.
