Analysis of information sources in references of the Wikipedia article "Prepona" in Portuguese language version.
Archaeoprepona and Prepona are very similar above, being dark brown with dazzling turquoise or blue bands. They can be distinguished by examining the underside hindwings. In Archaeoprepona there is a tiny submarginal ocellus in each cell, but in Prepona the ocellus near the apex, and the one near the tornus, are both greatly enlarged. Another difference is that Prepona males have tufts of yellow androconial scales on the hind-wings whereas in Archaeoprepona these are black.
Using data from DNA sequences, Ortiz-Acevado and Willmott (2013) classified Preponini as follows: two genera were synonymized, Noreppa to Archaeoprepona and Agrias to Prepona.
A diferencia del género Prepona Boisduval que solo ostentan dos pequeños ocelos en un fondo mucho más críptico. Tales patrones de coloración (Agrias) guardan semejanzas sorprendentes con otros géneros de ninfálidos que viven en las mismas áreas (Callicore, Asterope, Callithea, Annagrapha, Temenis) constituyendo anillos miméticos complejos estudiados por DESCIMON (1976, 1986), DE LA MAZA & DE LA MAZA (1982) y SALAZAR (2004) del cual se extracta un ejemplo ilustrativo de analogía en coloración alar (Figura 7).
