Discussion: Oryzomyini . Zygodontomys was considered a member of the phyllotine group by Hershkovitz (1962), an affinity disputed by others ( Hooper and Musser, 1964 a; Olds and Anderson, 1989; Pearson and Patton, 1976), or as Sigmodontinae incertae sedis ( Reig, 1984; Voss, 1991 a). Classification in Oryzomyini formally proposed by Voss and Carleton (1993), a tribal relationship supported by Steppan (1995) and Bonvicino et al. (2003 d). First revised by Hershkovitz (1962), who included South American populations now allocated to Bolomys (= Necromys ) lasiurus (see Maia and Langguth, 1981; Reig, 1987; Voss and Linzey, 1981). Generic definition emended and species taxonomy revised by Voss (1991 a), as followed here; in addition to the two species that Voss recognized, Reig (in Reig et al., 1990 a) considered microtinus as valid, a possibility that deserves further exploration. Karyology reported by Gardner and Patton (1976, Costa Rica and Colombia), Reig et al. (1990 a, Venezuela), and Mattevi et al. (2002, Brazil); all karyotypes summarized as well as new variants reported by Bonvicino et al. (2003 d).
