Diagnosis. Chimoptesis rubigo is related to C. phanera ; in facies it is similar to C. castanescens , but C. rubigo can be distinguished by the strong, curved folds of the subgenital sternite.

Description. Wing span 18 mm. Male: Unknown. Female: Head and thorax cream, labial palpus brownish laterally, tegula brown. Forewing weakly expanding terminally; termen somewhat oblique, indistinctly sinuate. Ground colour yellowish olive, suffused brown, strigulated grey-brown, tinged rust posteriorly, suffused whitish postmedially; costal strigulae minute, cream; divisions dark brown. Markings reduced to brown rust median fascia with rust dorsal part; apical area and part of termen rust brown. Variation in forewing ground colour with one paratype brownish cream, more rust in posterior area; dorsal patch cream tinged rust; costal strigulae cream; divisions brown; ocellus with weak spots and lines; markings brown. Cilia brown, suffused black especially at apex. Hindwing brownish cream, browner on peripheries; cilia paler.Genitalia ( Fig. 15 ) with posterior part of sterigma broad, with short postostial portion; antrum sclerite tubular, uniformly broad in proximal half; folds of subgenital sternite distinctly curved; cingulum rather short, fused with additional weak sclerite; signa large.

Holotype female. " Mexico: Chiapas, San Cristobal de las Casas, 2300 m, 23–27.VI.1981, V.O. Becker Col; Col. Becker 43786"; GS 833 WZ. Two female paratypes with identical label data; one with GS 846 WZ.
