Diagnosis. Chimoptesis cornigera is related to C. matheri Powell, 1964 , but C. cornigera is easily distinguished from all congeners by a pair of long, slender, curved, horn-like processes from the base of the uncus. The female genitalia differ from those of C. matheri by a longer sclerite of the antrum and a longer cingulum.

Description. Wing span 18 mm. Male: Head whitsh grey; thorax creamer with grey marks. Forewing slightly expanding terminally; termen concave beneath middle. Ground colour white, sprinkled and strigulated blackish; ocellar area indistinct. Cilia whitish black scaled. Hindwing whitish grey, mixed brownish grey posteriorly. Cilia whitish. Genitalia ( Fig. 9 ) with uncus very broad with triangular lateroposterior prominences and a pair of long, slender, curved basal processes; socius broad, rather short, densely scaled; angle of sacculus distinct; neck of valva short, ventral incision rounded; cucullus broad; aedeagus simple.

Female: Head and thorax as in male. Genitalia ( Fig. 23 ) with posterior part of sterigma ovoid; sclerite of antrum uniformly broad; folds of subgenital sclerite broad, reaching lateroproximal corners of sclerite; proximal part of cingulum broad, as long as antrum sclerite; signa fairly short.

Holotype male: " Mexico: [Nuevo Leon], C[erro] Potosí, 2300 m, 23. VI. 1997, V.O. Becker Col; Col. Becker 110440 "; GS 1345 WZ. Four paratypes with similar label data, one female with GS 1346.

Etymology. The name refers to the paired slender horn-like processes of the male genitalia: Latin: cornus—a horn, gero—I carry.
