Type species: Peronea acmanthes Meyrick, 1931 a, by original designation.

Diagnosis. Acmanthina includes two species, A. acmanthes (Meyrick) and A. albipuncta Brown , both of which are recorded from Chile and Argentina. Adults are moderately small, with a dark forewing bearing variable white patch(es) and/or band(s), superficially most similar to some species of Apotomops and Bonagota (see Brown 2000b for photographs of adults). Males can be distinguished from those of related genera by the absence of the fine, elongate scales along the basal portions of hindwing veins CuP and 1A+2A, the possession of a long, slender hairpencil of setiform scales concealed in a deep fold of hindwing vein CuP, and the deeply excavated mesal portion of the juxta, all of which are interpreted as synapomorphies for the two included species ( A. acmanthes and A. albipuncta Brown ). Male genitalia are illustrated in Figs. 12 and 13 . Females of Acmanthina lack the accessory pouch from the ductus bursae that is present in Bonagota and Apotomops ( Fig. 24 ).

The hindwing hairpencil consists of a fascicle of 20–24 long, fine, slender, setiform scales, unlike the distally spatulate scales of the hairpencil of male Ptychocroca .
