Hist., 294: 111, could not assign this species to any of the currently recognized taxa, but pending examination of the type left this species incertae sedis. See Cole, Townsend, Reynolds, MacCulloch, and Lathrop, 2013, Proc. Biol. Soc. Washington, 125: 402, for brief account and records for Guyana.
