DIAGNOSIS. Amorbia exsectana can be distinguished from its congeners by its dorsal pit represented by a shallow indentation and by the absence of the costal fold in the male FW.

REDESCRIPTION. MALE. FW length 8.8–9.2 mm (mean = 9.0; n = 4). HEAD: Frons convex, naked. Vertex brownish, antenna brownish. Labial palpus brownish concolorous with head scaling laterally, inner surface paler; junction of segments II and III at an oblique angle. THORAX: Dorsum smooth scaled, brownish; tegula concolorous. FW ground light brown, basal, median and subterminal fasciae, including apex, dark brown. A band of darker scales from median fascia (at M2 position) reaching subterminal fascia towards apex. Costal fold absent. HW cream. ABDOMEN: Dorsal pit as a shallow indentation. Genitalia as in Fig. 82 (slide # EPR43, VBC, Brazil, Río de Janeiro; n = 2). Uncus extending beyond socii. Transtilla rectangular, with spines in two groups. Sacculus well defined, 0.6X length of valva, extending beyond margin of valva. Aedeagus 0.8X length of valva, hook-shaped.

FEMALE. FW length 10.0–11.0 mm (mean = 10.8; n = 3). HEAD and THORAX: As described for male. ABDOMEN: Genitalia as in Fig. 105 (slide # EPR42, USNM, Panamá; n = 1). Lamella antevaginalis developed into lateral pockets, triangularly rounded anteriorly; median sinus rounded; rim of ostium sclerotized. Ductus seminalis arising at 0.2 length of ductus bursae from ostium. Ductus bursae 2.0X length of lamella antevaginalis, broadened anteriorly, sclerotized posteriorly.

TYPE MATERIAL. Holotype: Female , Colombia ( BMNH).
