Distribution. Epipleoneura venezuelensis is known from Venezuela to Northeast Argentina, including Bolivia, Brazil, and Paraguay, and unpublished records from Ecuador (R.W. Garrison, pers. communication). So far, there are no records for the North of the Amazonas River basin or the West and North-East of South America.
Notes on the distribution of E. venezuelensis. Predictive and known distribution maps of E. venezuelensis (Figs. 5–6) largely coincide in South America. The species is probably distributed continuously throughout the center of the continent from west to east (south of the Amazon River basin and north of the Paraná River basin), in the southern Paraná River basin, and in northern South America. This disjunctive distribution observed between the north and center of the continent is striking. The species appears absent in the northern Amazon basin and from the central Paraná basin. Its absence in northern Amazonas is very likely because this region has received considerable (although perhaps insufficient) sampling. Nevertheless, the species probably has a continuous distribution between the southern Paraná River basin and the center of the continent. This basin includes part of Bolivia, Paraguay, and northeast Argentina, a region whose entomological fauna is still poorly known.
In the predictive distribution map obtained, there is an isolated presence of the species in the center-north of Argentina (Fig. 6). This distribution seems unlikely, as this region has been well sampled for several decades without the genus being found. Similarly, the distribution of E. venezuelensis in Central and North America is highly unlikely because the genus is not known for those regions. The greatest diversity of the damselflies formerly included in Protoneuridae is represented in South America, with only Neoneura Selys, 1860 and Protoneura Selys in Sagra, 1857 and to a lesser extent, Drepanoneura, and Psaironeura Williamson 1915 distributed north of the Neotropics, reaching Central and North America (Garrison et al. 2010).
