Resumen:
ABSTRACT. We comment on the geographical distribution of the 3 recognized species of Bibimys, focusing inthe type species, B. torresi. By briefly reviewing the fossil occurrence of this form we posit that the speciessuffered a very recent marked retraction. Based on few collected individuals belonging to B. chacoensis andB. torresi, we describe some external traits, such as their unique mammary dotation composed by 2 pairs locatedmore caudally, 1 of them laterally to the genitalia. Combining morphology with direct observation of a wildindividual we advance that Bibimys is not a fossorial or semi-fossorial form but a specialized sigmodontinefocused on the active search for food employing mostly the nose.
