Remarks. The males imagos sampled in Piauí State (Fig. 11A–D) were caught up in the evening at the riparian environment under a dense canopy cover. Instead of a well-developed bridge between the stalks of the compound eyes, as reported in the literature or based on examined material from Bahia state (Fig. 11E) and Colombia (Fig. 11F), some of these imagos from Piaui state (n = 4) present only a small protuberance. According to Peters & Domínguez (2001), the presence of these protuberances is a subimaginal character, which in imagos develop to the bridge characteristic of the species. In order to complement the description of the species, herein we report the absence of this bridge in some of the examined imagos (Fig. 11C–D).
Distribution. Brazil (Amazonas, Bahia, Espírito Santo, Mato Grosso [new record], Minas Gerais [new record], Roraima, and Piauí [new record]), Colombia, Guyana, Suriname, Venezuela.
