Petromyscinae



Taxobox-begin color pink name: Petromyscines Taxobox-begin-placement color pink Taxobox-regnum-entry taxon Animalia Taxobox-phylum-entry taxon Chordata Taxobox-classis-entry taxon Mammalia Taxobox-ordo-entry taxon Rodentia Taxobox-superfamilia-entry taxon Muroidea Taxobox-familia-entry taxon Nesomyidae Taxobox-subfamilia-entry taxon Petromyscinae Taxobox-end-placement Taxobox-section-subdivision color pink plural-taxon Genus Petromyscus, Delanymys Taxobox-end The subfamily Petromyscinae of the family Nesomyidae contains the rock mouse and Delanys swamp mouse. These two genera of mice are distinctive enough from one another that they are sometimes each placed in separate subfamilies. The rock mouse are found in southwestern Africa. Delanys swamp mouse is found in a restricted range in parts of Uganda and adjacent Zaire. These animals have a sharp lower point to their V-shaped infraorbital canal. Their molars are intermediate between the ancestral cricetid style tooth and the dendromurine style tooth. The Petromyscinae contains two genus and 5 species.
