Cypseloides fumigatus (Streubel, 1848)

Listed by Silva and Oniki (1988) and Valadão (2012). A taxon difficult to identify, scarce in the region and which may be confused with Cypseloides senex . Cypseloides senex was recorded by us several times and does not feature in the lists by Willis and Oniki (1990) and Valadão (2012). We stress that at times we have come across individuals of genus Cypseloides without being able to identify them at the species level, so it is possible that both species occur at EESA.
