This illustration depicts Isothrix barbarabrownae, a newly discovered species of Neotropical rodent, in its arboreal habitat. The strikingly unusual animal has long dense fur, a broad blocky head, thickly furred tail and a blackish crest of fur on the crown, nape and shoulders. It is about the size of a squirrel.
