GENUS Pseudoryzomys

Author:Hershkovitz, 1962.
Citation:Fieldiana Zool., 31: 208.
Type Species:Oryzomys wavrini Thomas, 1921 (= Hesperomys simplex Winge, 1887).
Comments:Oryzomyini. Associated with phyllotines by Hershkovitz (1962) and viewed as the tribe’s most ancient clade by Braun (1993). However, excluded from Phyllotini by Olds and Anderson (1989), and oryzomyine characteristics illuminated by Voss and Myers (1991). Formally allocated to Oryzomyini as the tribal diagnosis was phylogenetically recast by Voss and Carleton (1993); the morphology of the glans penis also supports this tribal assignment (Langguth and Silva Neto, 1993) as do other morphological traits (Steppan, 1995). See Voss and Myers (1991:418) on the formal availability of the genus-group name.
