Diagnosis. Aristotelia barriosi sp. nov. is a rather distinctive species of Aristotelia that externally differs from others by the uniformly reddish-brown coloration and two ferruginous maculae at 1/3 of costa and at the apex of the forewing. The blackish-grey dorsum of the abdomen contrasting with the pale brown terminal segment in males is very characteristic too. The male genitalia are recognizable by the deeply bilobed uncus which is unique for Aristotelia . The female genitalia are characterized by a very long and coiled ductus bursae with a short, sclerotized antrum and a stellate signum.

Description. Adult ( Figs 1–2 ). Head light brown. Antenna light brown except for external margin of flagellomeres dark brown. Labial palp brown, second segment with tuft of scales on outer margin. Thorax light brown except for sprinkled dark brown scales covering apical portion of tegulae. Wingspan 8.5 mm in males and 11–13 mm in females. Forewing light brown, large dark brown irregular spot at 1/3 of costa, small dark brown spot before apex, pink points on costa just after large costal spot and before small apical spots, separated pink scales along veins in distal half of forewing and on dorsal margin before apex, costal margin suffused with dark brown in distal half, cilia brown black-tipped; hindwing blackish grey, cilia dark grey. Abdomen in female brown except for segment II melanized; in male abdominal terga black except for segment II brown. Tergum VIII in the males with dorso-lateral coremata, light brown.

Male genitalia ( Figs 3–5 ) with uncus deeply bifurcated, inner margin setose, setae evenly distant; mesial sclerite of gnathos hook-shaped with blunt apex; tegumen elongate, about three times longer than broad, anteromedial emargination moderately narrow, reverse U-shaped, extended to 1/4 length of tegumen; valva slender, of even width, gradually bent in middle, apex with very short pointed tip, covered with short setae in distal half; sacculus about 1/8 length of valva, covered with long hair-like setae; posterior margin of vinculum with broad subtrapezoid projection extended to 2/3 length of sacculus; saccus broadly rounded, base with posterior sulci missing; phallus subequal length with tegumen, caecum rounded, 1/3-1/4 length of phallus, distal portion slender, weakly curved in middle, with fine teeth on dorsal surface just beyond middle, apical 1/4 gradually narrowed towards rounded apex; ductus ejaculatorius slightly shorter than phallus.

Female genitalia ( Figs 6–7 ) with papillae anales subtriangular, rounded posteriorely, setose, setae evenly distant; apophysis posterior two times as long as apophysis anterior; segment VIII subquadrate, about half length of apophysis anterior, sternum VIII evenly sclerotized, posterior margin with deep narrow medial emargination; apophysis anterior straight; ductus bursae long, with five coils anteriorly, antrum sclerotized, approximately half length of apophysis anterior; corpus bursae rounded, covered with microtrichia; signum plate transverse elongate, about half length of corpus bursae, perimeter thickened edged with large triangular teeth.

Biology. Unknown. The type series was collected in the second half of June at 900 m.

Distribution. Panama: Veraguas, Santa Fe National Park.

Etymology. The species is named in honor to Prof. Hector Barrios Velazco, a founding member of the Central American Program of Entomology in Panama, in the recognition of his valuable contribution to the Panamanian systematic entomology.
