Range
Known in our range from Bernalillo Co., NM. Summarizing from one image post, which includes contributions from D. Christopher Rogers:
This species has heretofore apparently only been reported from Venezuela, Colombia, Mexico(1), and Brasil(2). Rabet 2010(3), however, states, "the occurrence of this species in Colombia is not established". This is due to confusion with a Venezuelan locality. It also states, "Localities in Mexico (Daday de Deés 1926(4)) should be confirmed by genetic or egg morphology studies". Regarding the latter, Belk 1989(5) concludes that adult morphology is generally inadequate for species ID in this genus, and that use of egg features is required. In addition, Maeda-Martinez et al. (2002)(6) report that the specimen used for Daday de Deés 1926 was badly damaged and not properly identifiable. And, Maeda-Martinez et al. (2002)(6) state that they have not found any material in Mexico that matches E. geayi." The Bugguide post, therefore, is the first valid record for North America.
