Diagnosis. Hoplosauris schausi can be distinguished from the other species of the genus by: spherical corpus bursae (autapomorphy); length of the ductus bursae approximately 1/8 of the total length of the corpus bursae; straight uncus; and cornuti, a group of short and thick spines.

Redescription. Male ( Figure 1a): Head: Antennae sub-apically thickened, covered by white scales mixed up with some brown scales. Frons and vertex covered mainly by white scales and few brown scales. Labial palpi with a brownish apex and white base. Thorax: dorsal surface of the thorax covered by brown and white scales. Patagia and tegula similalarly covered. Tegula with hair like scales extending posteriorly. Forewings: ground colour of upperside grey with slight brownish tinge, basal area brown, antemedial and postmedial lines dark brown, the latter crenulate, terminal area with dark brown shades. Discal mark dark brown. Ventral surface light brown. Hindwings: reduced and with hairy concave vesicle on anal margin; upperside light brown. Underside whitish. Discal mark dark brown. Coloration of abdomen similar to that of the thorax. Legs chequered dark brown and white. Female. similar to male, without reduced hindwings and without a hairy concave vesicle on the anal margin. Male genitalia ( Figures 2a, c). Uncus straight and narrow, slightly setose, with acute apex, approximately equal to length of valvae, basis subtriangular. Valvae sub-rectangular, with androconia at sub-apical position. Costa slightly sclerotized. Ventral margin of the valvae transversally striate. Saccus semicircular. Aedeagus broad, tubular, vesica with a group of short and thick cornuti, approximately 1/ 3 the length of the aedeagus. Female genitalia ( Figure 2b). Sterigma membranous. Corpus bursae subspherical, membranous, with microspines on internal surface, except for the most anterior part. Anterior apophyses approximately ¼ length apophyses posteriors. Ductus bursae short, 1/8 the length of corpus bursae. Ductus seminalis indistinguishable.

Distribution. This species occurs between 36º S and 40º S, in the provinces of Ñuble and Valdivia.

Flight period. Specimens were captured in September, November, January and March. There are no records for other months.
