Diagnosis. Hoplosauris macarenae can be distinguished from the other species of the genus by dark reddish scales covering the forewings, head and thorax. Male uncus with a blunt apex. Microspines located on the posterior half of the corpus bursae. These two characters are the autapomorphies for the species. Subrectangular saccus.

Description. Male ( Figure 1c). Head: Antennae sub-apically thickened, covered by light reddish scales. Vertex and forehead with dark brown scales. Labial palpi with white apex and brown basis. Thorax: white, the same for the patagia and tegula. Tegula with piliform scales extending posteriorly. Forewings: upperside whitish. Basal line dark brown reddish. Stripe, located between the basal and medial lines, whitish. Medial line brown becoming reddish towards its basis, the rest light brown reddish. Medial line border brown becoming reddish towards the apex. Postmedial line dark brown reddish and orange towards its apex. Terminal line represented by brown semicircles. Discal mark brown reddish. Underside light brown reddish, lighter towards the anal margin of the wing. Hindwings: reduced and with a hairy concave vesicle; upperside whitish, underside whitish with a brown reddish discal cell. Abdomen whitish, with a tuft of scales on the sides of the medium region. Fore and mid legs with white and dark brown intercalated stripes. Hind legs white. Female. Similar to the male, without reduced hindwings and without a hairy concave vesicle on the anal margin. Male genitalia ( Figures 5a, c). Uncus curved, with a blunt apex, subtriangular base, approximately ½ to length of valvae. Valvae sub-rectangular, with androconia at sub-apical position. Costa slightly sclerotized. Ventral margin of the valvae with neckline on its subapical region. Saccus subrectangular. Aedeagus tubular, vesica with a group of short and thick cornuti (microspines); approximately ½ the length of the aedeagus. Female genitalia ( Figure 5b). Sterigma membranous. Corpus bursae sclerotized, elongated, striate, with microspines on its internal surface distributed on posteriorly. Ductus bursae ¼ the length of corpus bursae. Ductus seminalis indistinguishable.
