SIGMODONTINAE, a diverse subfamily including 106 genera of American Rodents, is currentlydivided in eleven tribes that still need to be refined based on recently generated phylogenetichypotheses. Several published names of tribes do not conform to one or more Rules of theInternational Code of Zoological Nomenclature. In particular, the first arrangement ofSIGMODONTINAE genera in tribes has been overlooked, the different requirements for availability ofnames proposed before 1931 and after 1930 were not taken into account for at least five names, therequirement that a family-group name be used as valid in the publication where proposed, and theunavailability of names proposed conditionally after 1960 were also ignored on several occasions.Our analysis tries to disclose and fix such nomenclatural problems keeping current usage as much aspossible. A new name is proposed for a tribe that currently has been designated only by anunavailable name.
