T. barrerae (B. Lawrence, 1941) T. kirchnerorum Teta et al., 2014 T. loschalchalerosorum Mares, Braun, Barquez & Diaz, 2000 †T.

[4] T. loschalchalerosorum was formerly considered to be monotypic within the genus Salinoctomys, but has been shown by genetic analysis to nest within the variation of T.

[4] All species are endemic to central western Argentina, where the genus has a fragmented range.

Their natural habitat is desert scrubland, dunes and salt flats, where they eat halophyte plants.

They are solitary, nocturnal rodents that construct large mounds with complex burrows.
