Vergara leg.; MZUC-UCCC. — Capitán Prat Prov. • 1 male; pinned; Cochrane; 11-IV-2008; Parra and Alvarado leg.; “ sampled in scrub of Notro-Ñirre ” [labeled] (Embothrium coccineum (Proteaceae) - Nothofagus antarctica (Nothofagaceae)); MZUC-UCCC. Diagnosis. This species is distinguished from the other species in the genus by the presence of elongated blackish marks with small whitish point at the level of veins in the postmedial band of the forewings, which are not visible in ventral view. In the male genitalia, it differs from D. aspersa by the elongated and striated furca, more similar to that of D. cervinaria. It also differs from D. cervinaria because it has spines around the distal half of the furca. This species stands out for the presence of a U-shaped gnathos with an expanded apex like a denticulate plate, transtilla with a digitiform process at the apex, and aedeagus with a fine and elongated caecum, half the total length of the aedeagus. Description. Male (Fig. 2 N, O). Head: antennae slightly serrate; palpi long, one-third longer than the eye diameter, porrect; frons and vertex covered with grayish brown scales. Thorax: patagia covered with elongated scales of same color as background; tegulae covered with piliform scales of same color as background; tibial spur formula 0-2 - 4. Forewings: subtriangular with acute apex and outer margin excavated between apex and M 3, with slight mucronate extension; fovea absent; pale ashy background with a large number of small blackish spots scattered over the surface; antemedial band diffuse, slightly zigzagging, marked by three dark brown points at the level of radial, cubital, and anal veins respectively; medial band light brown, diffuse; postmedial band, diffuse, light brown, with bicolored spots (elongated blackish mark with the center marked by a whitish point) at the level of veins R 4, R 5, M 1, M 2, M 3, CuA 1, CuA 2, and 1 A + 2 A, not visible on ventral surface. Hindwings: subrectangular with small mucronate apex at the level of M 3; pale ashy background, without visible bands or spots; discal spot visible. Male genitalia (Fig. 7). Uncus conical, apex club-shaped; gnathos U-shaped with an expanded apex like a denticulate plate; valvae subrectangular, costa strongly sclerotized with a distal lobe before the apex, rounded, and cucullus extended beyond the apex of the costa; transtilla bifid; saccus membranous, weakly defined; juxta poorly defined, with a central depression and furca, long, surpassing the height of the gnathos, club-shaped with two longitudinal stripes, densely spiny towards the distal half; anellus sclerite weakly defined. Aedeagus tubular, straight; fine, elongated caecum, half the total length of the aedeagus; vesica without cornuti. Female. Unknown. Etymology. The species name is an adjective from Greek aprocryphos (“ not genuine ”), referring to the deceptive maculation pattern, superficially resembling Digonis aspersa Butler. Distribution. This species is found between the provinces of Diguillín and Capitán Prat. It is distributed in parts of the biogeographic provinces of Maule, Valdivian Forest, Magellanic Forest, Subantarctic subregion, in the Andean region. Flight period. Specimens were captured in February, March, April, and May. There are no records for other months.
