Comments. This species is distributed in northern South America, Central America, and southern Mexico. It has been founded naturally infected with T. cruzi and in peridomiciliary and intradomiciliary habitats, especially in northern South America where it is apparently more abundant ( Lent & Wygodzinsky 1979, Dib et al. 2009). Specimens of E. cuspidatus collected in Veracruz came from Estación de Biología Tropical “Los Tuxtlas” and were studied by H. Brailovsky. All were male specimens attracted to light traps in different years from 1975 to 1993 ( Zárate & Zárate 1985, Ryckman 1984, 1986, Ibáñez-Bernal et al. 1995).
