IDENTIFICATION: The systematics and taxonomy of this subgenus is still confused and future taxonomic changes will probably be necessary due to the high molecular diversity in this group (e.g., de la Sancha et al., 2011 ). We consulted the descriptions and measurements of Marmosa ( Micoureus ) regina provided by Hice and Velazco (2012) , Patton et al. (2000) , and Voss and Jansa (2009) . Our single specimen conforms in all respects to the morphology previously described for Marmosa regina (e.g., dense but short fur, base of the tail covered with fur [< 20 mm ], palatine fenestrae absent). REMARKS: Our single specimen was caught in a Victor rat trap in a forest.
