GENUS Microakodontomys

Author:Hershkovitz, 1993.
Citation:Fieldiana Zool., N.S., 75: 2.
Type Species:Microakodontomys transitorius Hershkovitz, 1993.
Comments:Oryzomyini. Provisionally left as Sigmodontinae incertae sedis by Hershkovitz (1993:2), who remarked that "Overall resemblance to Microryzomys and Oligoryzomys suggests differentiation from an oryzomyine stock in a scrub brush habitat transitional between forest and savanna." To us, the holotype displays features that clearly ally it with Oryzomyini sensu Voss and Carleton (1993). Founded on a single young specimen with damaged skull, the diagnostic traits of this new genus and species, which "could be mistaken for a well-differentiated species of Oligoryzomys" (Hershkovitz, 1993:4), should be verified with improved series from the type locality.
