Tegulae light gray. Labial palpi brown, rather long, twice as long as longitudinal eye diameter. Antennae thin, black. Length of fore wings 21 mm. Fore wings light up to middle part, with small areas of dark scales. In distal part, fore wings black with bright white areas: in form of sinuous bands on both lobes and in form of irregular bright white spots above cleft base. Fringe along posterior margin of fore wing light gray with two distinct areas of black scales. Fringe inside cleft light. First lobe pointed apically. Hind wings unicolorous, light gray. Fringe on third lobe of hindwings also light gray with distinct portion of black scales in its middle part. Individual black scales on fringe of third lobe, at its base. Hind legs dark brown with lightened areas of scales at spur base and on tarsus.

Male genitalia. Valvae symmetric, cucullus arched, slightly pointed apically. Sacculus two-lobed, basal part wide, two-thirds of valva length. Uncus rather long, elliptically widened at apex. Tegumen two-lobed. Anellus arms symmetric, wide. Aedeagus arched, with narrow elongated cornutus in middle part, aedeagus basal process wavy, equal to caecum in length.

Diagnosis. The new species is similar to Stenoptilodes medius Gielis, 2006 in the general structure of male genitalia, but is distinctly different in arched aedeagus with a rather long basal process and the presence of cornutus, as well as elongated cucullus at the valva apex.

Distribution. Colombia.

Flight period. January.

Etymology. The new species is named in honor of Rodrigo Bernali, Colombian botanist specializing in the study of the palm family ( Arecaceae ). Rodrigo and his wife Blanca Martinez share a profound interest in insects, particularly Lepidoptera , and they engage in environmental education of the population, through the publication of posters and books ( Bernal & Martinez 2023).
