 Transitional colilargo

The transitional colilargo ("Microakodontomys transitorius")  also known as the intermediate lesser grass mouse, is a species of rodent in the tribe Oryzomyini known only from two individuals found in the Federal District of Brazil.Although described as a link between oryzomyine and akodontine rodents and placed in its own genus, Microakodontomys, Weksler and coworkers dismissed it as an aberrant "Oligoryzomys".
