Pseudomys shortridgei (Thomas, 1907) . Proc. Zool. Soc. Lond., 1906:765 [1907].

TYPE LOCALITY: Australia, SW Western Australia, neighborhood of Woyerling Reserve, 973 ft (additional information in Mahoney and Richardson, 1988:180) .

DISTRIBUTION: Australia; SW Western Australia and SW Victoria (Grampian Mtns and Portland areas); see map in Watts and Aslin (1981:185).

STATUS: U.S. ESA - Endangered; IUCN - Vulnerable.

COMMENTS: Thought to be extinct in Western Australia ( Watts and Aslin, 1981), but recently rediscovered there ( Baynes et al., 1987). Electrophoretic data suggested P. shortridgei is phylogenetically isolated from all other species of Pseudomys ( Baverstock et al., 1981) ; spermatozoal morphology unlike most other Pseudomys but similar to that of P. delicatulus , P. novaehollandiae , and P. pilligaensis (Breed, 1983) ; phallic anatomy linked P. shortridgei to P. albocinereus and P. fumeus , a group that could be generically recognized by calling it Gyomys ( Lidicker and Brylski, 1987:635) .
