Hoplosauris morenoi Ramos-Gonzalez & Parra sp. n. Figures 3, 4, 11, 12, 18

Diagnosis.

This species and H. heliconoides Butler share the following characters: valvae with sclerotized costa and apically rounded; in females, two-thirds (or more) of corpus bursae with longitudinal striation. However, in the case of H. morenoi there are microspines on the sclerotized longitudinal striation only in the mid-ventral region (autapormorphy). The external morphology is highlighted by the grayish forewing, which is crossed by coppery-brown bands.

Description.

Male (Fig. 3). Head: antennae filiform, subapically broadened; palpi porrect and subequal to eye diameter. Thorax: Patagia and tegulae covered by piliform ashy and brown scales. Tibial formula 0-2-4. Forewings: background color dark gray; termen rounded, with piliform dark-gray scales; basal band straight coppery-brown; antemedial band coppery-brown, slightly zigzagging; postmedial band coppery-brown, straight, twice as wide as the basal and antemedial bands; subterminal band whitish, zigzagging; apical spot slender and blackish which connects with subterminal band; terminal band formed by a dashed stripe of short coppery-brown spots; discal spot present and blackish. Hindwings: reduced, half the length of forewings, subrounded, pale ashy, with no visible modification at the base of anal margin; without discal spot. Wing venation in males (Fig. 18): forewing with two accessory cells; hindwing with Sc+R1 and Rs connected by a weak transverse vein, one third before the end of the cell; Rs and M1 pedunculated; M2 free and M3 and Cu1 pedunculated; discal cell triangular and extends for a quarter of wing surface; anal cell present, formed by a weak transverse vein towards the middle of the discal cell that connects cubital stem with anal margin. Male genitalia (Fig. 11): valvae ensiform, costa sclerotized and rounded, cucullus apically extended, subapical setal tuft brush-like; saccus subrounded; juxta with subquadrangular base and indented posterior apex, with two disjointed lateral processes that have subtriangular apex, these processes extend to the height of the transtilla; uncus setose and curved; socius triangular; transtilla projected in a Y-shaped, with apices unequal in length. Aedeagus tubular; cornuti arranged as two longitudinal groups in the vesica. Female (Fig. 4). Similar to males but with filiform antennae slighter and hindwings not reduced, subquadrangular and pale ashy. Female genitalia (Fig. 12): ductus bursae one-sixth the length of corpus bursae; corpus bursae subpyriform, sclerotized, with straight longitudinal striations that exceed two-thirds of corpus bursae and mid-ventral region with rows of microspines; posterior apophyses larger than anterior apophyses.
