COMMENTS: The only species of Maxomys with a range encompassing Indochinese and Sundaic faunal regions. The two groups of samples differ in morphological features, and the significance of this variation should be determined in a careful systematic revision of the genus. Berylmys bowersii, Chiropodomys gliroides, Leopoldamys sabanus, and L. edwardsi have roughly concordant geographic ranges and demonstrate similar geographic variation (Musser et al., 1979; Musser and Newcomb, 1983). Comparative spermatozoal morphology documented by Breed and Yong (1986), chromosomal and biochemical data summarized by Chan et al. (1979) in phylogenetic context.
