WA Museum Records and Supplements | Updated 1 decade ago

Abstract: Pseudomys laborifex sp. nov. is described from 20 specimens collected from widely separated localities in the Kimberley region, Western Australia.

Of the tropical and subtropical small (<20 gm) Pseudomys, P. laborifex is difficult to distinguish on external characters from P. hermannsburgensis and P. johnsoni using either univariate or discriminant function analysis; it is readily distinguished from these and P. chapmani and P. delicatulus on skull characters. Phenetically it is closest to P. johnsoni on both skull and external characters.
