discussion

Discussion: Corbet and Hill (1980), Hall (1981), Husson (1978), and Pine (1973) used Metachirops opossum for this species. Reviewed by Castro-Arellano et al. (2000, Mammalian Species, 638). The name D. larvata Jentink, 1888, is a nomen nudum. Didelphis opossum Linnaeus, 1758, is the type species for Holothylax Cabrera, 1919.
