Aemilia fallaciosa Toulgoët, 1997, 81 , figs. 3, 4, 7, 10.

Type material. Male holotype, female allotype [MNHN] and 39 paratypes [MNHN, BMNH]. Type locality: “ Honduras, P. Morazan, 24 km N.E. de Tegucicalpa [Tegucigalpa], La Tigra, 1900 m.”

Diagnosis. This is the most easily recognized member of the ambigua -group. The tooth-like mark at the distal end of the forewing cell and the presence of a lined posterior cubital vein are diagnostic. Other diagnostic characters are the small size (mean male forewing length 18.4 mm), and thin forewing vein lines. Internally, the basal lobes of the uncus are slightly flattened (globose in other species) and divided by a broad, u-shaped cleft, compared to the narrow, v-shaped cleft in other species.

Biology and distribution. Collection dates for P. fallaciosa are late May to late July and early September. It has been collected at elevations of 1400 m to 1900 m, from Chiapas, Mexico south to Guatemala and Honduras.
