507EDB7F3269FFA480DA6BCAFD75F8E8.taxon	diagnosis	Diagnosis: median sized Rhipidomys species (Total length ~ 275.75 mm; ONL ~ 32.61 mm), with brown to light orange dorsal pelage with cream venter. Tail (~ 144.5 mm) is longer than head-body length (HB ~ 131.25 mm) and ends in a tuft. The feet are wide, with a blackish dorsal metatarsal stain in juveniles and a grayish color in adult specimens. The interorbital region is anteriorly convergent. The subsquamosal foramen is narrow and elongated in adults, the hamular process is long, and the post-glenoid foramen is large (elongated). Incisive foramen rounded on the sides, with a drop shape. Mesopterygoid fossa extends beyond the plane of third upper molar, the roof sphenopalatine vacuities that ranged from small slits to slightly larger openings. Posterolateral palatal pits of medium and small sizes at the edge of the mesopterygoid fossa (Fig. 2). In the mandible, the angular process ends in the same position of the end of condyloid process.	en	Lanes, Rayque De Oliveira, Bonvicino, Cibele Rodrigues (2023): Reevaluation of Rhipidomys emiliae (J.
