Lenothrix Miller, 1903 . Proc. U.S. Natl. Mus., 26(1317):466.

TYPE SPECIES: Lenothrix canus Miller, 1903 .

COMMENTS: Chromosomal and biochemical data suggested a close phylogenetic link between Lenothrix and Niviventer ( Chan et al., 1979) , but derived dental morphology is shared with Pithecheir , and spermatozoal conformation is highly divergent from any Sundaic murine. In sum, Lenothrix is a Sundaic endemic characterized by many primitive external, cranial, dental, and chromosomal features and a few derived dental and spermatozoal traits; despite several claims, its phylogenetic relationships still require illumination (see discussions in Breed and Yong, 1986; Musser, 19816; Musser and Newcomb, 1983).
