DISTRIBUTION:

The Dominican Sphinx, Erinnyis domingonis (Wing span: 2 1/4 - 2 1/2 inches (60 - 65mm)), flies in Haiti and Jamaica south to
Venezuela;
French Guiana (HM)??;
Bolivia: La Paz;
Brazil: Sao Paulo: Curitiba (HM)??; and
Argentina: Cordoba, Tucuman, Salta (405m EB); Chaco and Misiones (JRR)
Paraguay: Presidente Hayes; with occasional sightings in Texas and Arizona and strays as far north as Nebraska.
Haiti is the specimen type locality.
Kitching and Cadiou, 2000, indicate E. domingonis might be a synonym of E. obscura. If they are distinct species, E. domingonis probably has the more limited range indicated above, and it might only be in Venezuela and the Caribbean.
E. obscura would have a much greater range, and the images on this page from Costa Rica, may in fact be E. obscura.
James P. Tuttle reports in his excellent book The Hawk Moths of North America, 2007, that he has reared larvae from eggs of a single female of Erinnyis obscura that have resulted in two different larval colour morphs. The emergent moths from this rearing showed two different adult morphs, a light form and a dark form (previously thought to be domingonis). He also reports there was no consistency between the larval morphs and the adult forms that resulted from them.
I do not know if DNA barcoding has resolved this issue???
I am pretty sure (January 2016) domingonis is a junior synonym of obscura.
