Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA MAMMALIA RODENTIA CRICETIDAE

Scientific Name: Necromys lenguarum
Species Authority: (Thomas, 1898)
Taxonomic Notes: The taxonomic status unresolved. It was demoted to subspecies under Akodon obscurus (Cabrera, 1961) or placed in full synonymy with Bolomys l. lasiurus (Macêdo and Mares, 1987), or generally if equivocally recognized as a species (Anderson 1997, Anderson and Olds 1989, Galliari and Pardiñas 2000, Reig 1987). Anderson (1997) maintained tapiropoanus, type locality in Mato Grosso, W Brazil, as a subspecies for Bolivian populations. Also see remarks under N. lasiurus. It was previously known in Peru as Bolomys lasiurus, collected in Pampas del Heath (Pacheco et al. 1995).
