Anoura aequatoris– While a 2006 morphological study suggested elevating Anoura caudifera aequatoris to species level, this conclusion has been challenged.
Some believe that it is not distinct enough to warrant separation from A. caudifera, and that further analysis is needed. A 2008 study challenged that elevating it to a species overstated the amount of diversity within the genus, and that it should remain a subspecies. It has not been assessed as a species by the International Union for Conservation of Nature. The status of this taxa is still in dispute.
Cadena's tailless bat, A. cadenai– The same 2006 study as above split A. cadenai away from A. caudifer. Again, this taxa has not yet been assessed by the IUCN. It was challenged by the same 2008 study based on the overall small sample size of the 2006 study, and the small morphological differences between A. caudifer and A. cadenai.A. caudifer has subsequently been considered monotypic by others, disregarding A. cadenai. The status of this taxa is still in dispute.
Anoura carishina– This taxa was named and described in 2010 based on morphology, and differentiated a species that had previously been described as Anoura geoffroyi. The IUCN has not assessed this taxa. Principal component analysis of A. carishina and A. geoffroyi have produced conflicting results on whether they describe the same species. Using mixture models, another kind of analysis method, shows that A. carishina and A. geoffroyi are indistinguishable. The status of this taxa is still in dispute.
