This species was described by
Robert Fisher Tomes, an English
zoologist, in 1862. In 1955, Emmett T. Hooper, an American zoologist, would
lump this species with
Neotoma mexicana, arguing that the two species were too similar where their respective ranges met. The two species would be considered loosely the same species until 2014, when a revision of the
mexicana species group (at the time only containing
Neotoma mexicana and
Neotoma chrysomelas). This study found
N. ferruginea &
Neotoma picta to be distinct species, with the former having several
subspecies. An additional study in 2021 referred more subspecies to this species, and showed
N. ferruginea to be the
sister species to
N. picta from southern Mexico. There are seven subspecies: •
Neotoma ferruginea ferruginea •
Neotoma ferruginea chamula •
Neotoma ferruginea isthmica •
Neotoma ferruginea parvidens •
Neotoma ferruginea solitaria (but see below) •
Neotoma ferruginea tropicalis •
Neotoma ferruginea vulcani Molecular work has been done on all the subspecies except
Neotoma ferruginea solitaria, but it is likely a subspecies of
ferruginea given its range being so far removed from other
Neotoma species. This species is recognized by the
American Society of Mammalogists, but not by the
IUCN. ==Description==
