DISTRIBUTION:

The Automeris basalis moth (wingspan: males: 54-70mm; females: 69-84mm) flies in
southeastern Paraguay: Canindeyu, AltoParana, Guaira, and (probably/possibly Caaguazu, Caazapa and Misiones and (Itapua: confirmed by Paul Smith, early March 2008); and
southeastern Brazil: Minas Gerais: Sao Roque de Minas; Rio de Janeiro Lectotype; Sao Paulo; Parana; Santa Catarina, Rio Grande Do Sol; at elevations from 300-1200m. I suspect it is also present in
Misiones, northeastern Argentina (confirmed by Fernando Penco, May 2008 and Ricardo Domingo Moyano, March 4, 2022).
