Diagnosis. The male genitalia of A. arenalana are most similar to those of A. rastafariana , especially in the broadly rounded aspect of the distal portion of the valva from the apicoventral angle to the apex of the costa. Anopinella arenalana can be distinguished by the extremely broad distal process of the gnathos, which appears to represent an autapomorphy for the species; it also is considerably smaller than A. rastafariana . The female of A. arenalana is unknown.

Description. Head: Frontoclypeus pale yellowish brown, vertex pale yellowish brown intermixed with some yellowish brown scales tipped with reddish brown; labial palpus with outer surface yellowish brown intermixed with reddish brown and brown, inner surface pale brown. Antenna with scape pale brown intermixed with few brown scales; basal 6­10 flagellomeres brown; distal flagellomeres pale brown.

Thorax: Tegula and mesonotum pale yellowish brown intermixed with reddish brown and brown. Forewing (Fig. 67) length 6.5 mm (n = 2); incomplete basal fascia and costal blotch brown intermixed with reddish brown, dark brown, and grayish brown, separated by a wide, oblique, pale band of white intermixed with few pale reddish brown scales demarcating an subtriangular costal blotch, except on posterior end; band recurved from distal costa through subapical area to tornus, encircling an elliptical ocellus, except for the posterior end; ocellus pale gray, nearly indistinct; costal blotch with a small, subrectangular white spot near posterior end; area between CuP and posterior margin pale reddish brown intermixed with few brown and dark brown scales; apical area yellowish brown intermixed with reddish brown and grayish brown; submarginal area reddish brown intermixed with grayish brown. Fringe pale reddish brown. Hindwing pale gray, with irregular mottling, gradually darkening from base to apex.

Abdomen: Male genitalia ( Fig. 10 ; drawn from JWB slide 1073; n = 2) with uncus curved at ca. apical 0.4. Socius digitate, ca. 0.65 length of basal portion of gnathos arms. Gnathos arms long, distal ca. 0.5 greatly enlarged, upturned, mostly non­dentate. Valva comparatively broad, densely setose from cucullus to basal ridge; ventral margin broadly rounded from base to end of sacculus, gently curved from sacculus to apicoventral angle, outer margin broadly curved dorsally from apicoventral angle to apex of costa. Phallus simple, relatively short, basally rounded; vesica densely microtrichiate. Female unknown.
