Miscellany on <i>Bibimys</i> (Rodentia, Sigmodontinae), a unique akodontine cricetid

We comment on the geographical distribution of the 3 recognized species of Bibimys, focusing in the type species, B. torresi. By briefly reviewing the fossil occurrence of this form we posit that the species suffered a very recent marked retraction. Based on few collected individuals belonging to B....

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