It’s curious that while Bousquet (2012) lists both fuscicornis and brunnicollis (and gives exact same ‘Coastal plain’ distribution for both), D&A and Ciegler both only describe and key brunnicollis. And the brunnicollis description appears to at least superficially match the only current BG image for fuscicornis. Does anyone know how these two are to be separated? (or if one should be a synonym of the other?)
