Two new records of Triatominae (Hemiptera: Reduviidae) from Roraima state, Brazil

“…The genus Eratyrus contains two species, E. cuspidatus and E. mucronatus, both being characterized by having the first segment of the rostrum very long when adults, ending at halfway the distance between the antenniferous tubercle and the anterior border of the eye; the scutellum having an oblique apical process with the shape of a pointed thorn, as lengthy as or lengthier than the main body of the scutellum (Galvão 2014;Páez-Rondón et al 2019).…”

“…In Brazil, E. mucronatus occurs in tropical rainforests in the states of Acre, Amapá, Amazonas, Maranhão, Mato Grosso, Pará, Rondônia and Tocantins, and is found in palm trees, rocks and tree hollows (Galvão et al 2003;Meneguetti et al 2011;Obara et al 2015;Rebêlo et al 1998). Since it has been found naturally infected with T. cruzi (Depickère et al 2012;Galvão 2014;Guhl 2007;Noireau et al 1995;Rojas et al 2008;Torres and Cabrera 2010) and is strongly attracted to artificial light sources, occasionally invading houses (Páez-Rondón et al 2019;Monte et al 2014;Morocoima et al 2010;Rangel-Avendaño et al 2011;Soto Vivas et al 2001), it can be regarded as a candidate vector of T. cruzi to humans. Therefore, it is important to have its occurrence updated and to identify the localities where this species has been found inside dwellings (Obara et al 2015).…”
