Type material. Holotype: ♂, HONDURAS: Copán Department, Copán Archaeological Site Ruinas, 14°50'13"N, 89°08'37"W, elevation caGoogleMaps  . 620 m, 15.ii.2012, A. Diškus, genitalia slide no. AD524♂ (ZMUC).

Diagnosis. From the most similar A. selvica  it differs in the apically rounded dorsal lobe of valva and the narrow gap between median lobes of uncus.

Male ( Figs. 83, 84View FIGURES 83–88). Forewing length about 2.9 mm; wingspan about 6.4 mm. Head: face pale brown; palpi brownish cream; frontal tuft comprised of brownish cream lamellar scales; pecten very prominent; antenna with about 36 segments, longer than half the length of forewing; flagellum ochre cream; sensillae very long and fine, brownish cream. Thorax ochre cream; tegula densely speckled with grey-brown scales, particularly densely anteriorly. Forewing slender, speckled with pale brown to dark brown scales, especially densely along costa in apical half of the forewing; most of the dark scales pale-tipped; apically forewing with an elongated, pale yellowish ochre patch; fringe pale brown on costal margin and tornus but yellowish ochre near to the apical patch; fringe-line indistinct, formed by a few black-brown scales; forewing underside brown, without spots or androconia. Hindwing brown on both upper and underside, except narrow edges on upper side which remain cream; no androconia; fringe pale grey-brown. Legs very contrasting in color: bright yellow cream to ochre cream, speckled with dark greybrown scales on upper side or ochreous cream scales distally.

Female. Unknown.

Male genitalia ( Figs. 7View FIGURES 7–10, 85–92View FIGURES 83–88View FIGURES 89–92). Capsule about 520 µm long, 265–280 µm wide. Uncus consisting of two slender, long, lateral lobes and two short, rounded, median lobes ( Fig. 86View FIGURES 83–88); the gap between median lobes narrow. Valva divided ( Fig. 7View FIGURES 7–10): ventral lobe slightly curved, about 360 µm long and rather wide ( Fig. 85View FIGURES 83–88); dorsal lobes consisting of two lobes: an inwardly curved, distally rounded lobe ( Figs. 89, 90View FIGURES 89–92) and more thickened, distally pointed lobe; transtilla absent; basal process of valva long ( Figs. 86View FIGURES 83–88, 89View FIGURES 89–92). Anellus with 5 setae, thickened only proximally ( Fig. 91View FIGURES 89–92), distally membranous. Phallus 640 µm long, distally bifurcated and without numerous fine spines ( Figs. 87View FIGURES 83–88, 92View FIGURES 89–92).

Bionomics. Adults fly in February. Otherwise biology unknown.

Distribution ( Fig. 233View FIGURE 233). Known from a single locality in Honduras, at an elevation of about 600 m ( Figs. 234, 235View FIGURES 234–238).

Etymology. This species is named after the Maya people, a Mesoamerican civilization in reference to the discovery of the species right in the Copán archaeological site, a world-wide famous Mayan ruins in Honduras.
