Rodent genera

Bramus is a genus of fossorial rodents. It formerly contained only the extinct North African species Bramus barbarus. Both species in Bramus were moved to this genus from Ellobius. They differ from Ellobius in being larger, having a distinct sagital crest, and other features of the teeth and skull. They also occur allopatrically from Ellobius. They are sexually dimorphic, with females being larger than males. The genus comprises two extant species: Southern mole vole, Bramus fuscocapillus (Blyth, 1843) Transcaucasian mole vole, Bramus lutescens (Thomas, 1897)

Stenocranius is a genus of rodent in the family Cricetidae. It contains the following species: Narrow-headed vole (Stenocranius gregalis) Radde's vole (Stenocranius raddei)
