Colombian Rhipidomys

<em>Rhipidomys caucensis</em>, commonly known as the Colombian Rhipidomys, is a small arboreal rodent species belonging to the genus <em>Rhipidomys</em> within the family Cricetidae. This species is classified as Data Deficient, reflecting a lack of sufficient information to accurately evaluate its conservation status, and indicating the need for further field investigation. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Rhipidomys</em> are typically arboreal, living in forest canopies and understories across the Andes and adjacent lowland regions of South America. These rodents are generally nocturnal and feed on a variety of plant materials including fruits, seeds, and other vegetative matter, though specific dietary records for <em>Rhipidomys caucensis</em> have not been documented. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient status underscores the importance of increased survey effort in Colombian forest ecosystems to better understand the distribution and ecological requirements of this arboreal rodent.
