Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Rodentia Echimyidae

Scientific Name: Makalata didelphoides (Desmarest, 1817)
Common Name(s):
English Brazilian Spiny Tree Rat
Makalata armata (I. Geoffroy, 1830)
Mesomys didelphoides (Desmarest, 1817)
Taxonomic Notes: This taxon is likely to contain several distinct species, however, studies are required to revise the taxonomy and distribution (Patton pers. comm.). Emmons (1993) concluded that the holotype for Echimys didelphoides was a young Makalata armata and therefore E. didelphoides Desmarest, 1817 antedates Nelomys armatus I. Geoffroy (1838).
