Conservation: IUCN – Lower Risk (nt).

Discussion: Type species of Thetomys . A close relative of P. gracilicaudatus to the exclusion of other species of Pseudomys , judged by analyses of electrophoretic data ( Baverstock et al., 1977 a, 1981); but a member of the group that includes only P. australis , P. gouldi , and P. higginsi based on phallic morphology ( Lidicker and Brylski, 1987); however, not distinctive relative to most other species in the genus as judged by spermatozoal form (Breed, 1983). Anatomy of mammary glands described by Griffiths and Simms (1993). Reviewed by Watts and Aslin (1981) and Robinson (1995 c).
