Diagnosis. Hoplosauris mabillei can be distinguished from the other species of the genus by the greenishbrown scales covering the head, thorax and abdomen. Forewing discal cell greenish-brown. Female genitalia with microspines located on the left wall and the centre of the corpus bursae. Male genitalia with long and thick spines on the vesica. These last three characters are the autapomorphies for the species.

Description. Male ( Figure 1d). Head: Antennae sub-apically thickened, covered by white and dark brown scales. Vertex and frons greenish-brown. Labial palpi dark brown. Thorax: greenish-brown, as in the patagia and tegula. Tegula covered by piliform scales extending posterioly. Forewings: upperside greenish-brown. Basal line brown greenish. Terminal line, greenish-brown semicircles. Discal mark dark greenish-brown. Underside greenish-brown. Hindwings: with a hairy concave vesicle on the anal margin; upperside whitish, with some dark greenish-brown scales. Underside whitish. Discal mark light greenish-brown. Abdomen covered by dark brown and white scales. Legs chequered white and brown. Female. Similar to the male, without reduced hindwings and without a hairy concave vesicle on the anal margin. Male genitalia ( Figures 6a, c). Uncus straight, setose, acute apex, triangular base, approximately ½ to length of valvae. Valvae subrectangular, with androconia at sub-apical position. Costa slightly sclerotized. Ventral margin of the valvae with little neckline. Saccus semicircular. Aedeagus tubular, vesica with two groups of long and thick cornuti. One group of spines twice the length of the other. The longest group of spines is approximately ½ the length of the aedeagus. Female genitalia ( Figure 6b). Sterigma membranous. Corpus bursae sclerotized, elongated, striated and membranous on its posterior half, with internal microspines distributed on the left wall and centre inner surface of the corpus bursae, occupying most of it. Anterior and posterior apophyses sub-equal. Ductus bursae ¼ the length of corpus bursae. Ductus seminalis discrete.

Distribution. This species occurs between latitude 33º S and 52º S, in the provinces of Valparaíso and Magallanes.

Etymology. This species is named after the XIX century French naturalist, M. P. Mabille.

Flight Period. Specimens were captured in February, May, July-October and December. There are no records from other months.
