Hybomys Thomas, 1910 . Ann. Mag. Nat. Hist., ser. 8, 5:85.

TYPE SPECIES: Mus univittatus Peters, 1876 .

SYNONYMS: Typomys .

COMMENTS: Carleton and Robbins (1985) provided a general review of morphometric traits, qualitative features, chromosomal data, geographic distributions, taxonomic assessments, and ecological and zoogeographical discussions of several species, with a focus on West African forms. The species have traditionally been arranged into two groups and reflected taxonomically as either subgenera ( Hybomys and Typomys ) or genera (see Rosevear's, 1969, excellent exposition). Results of biometric analyses led Van der Straeten (1984) to argue strongly for recognizing two genera. Carleton and Robbins (1985:983) corroborated that dichotomy with qualitative features and chromosomal data, but noted that whether “ Typomys and Hybomys merit generic segregation must await an evaluation of character variation among Hybomys and its near relatives."
