SUBFAMILY Chaetomyinae
Author: | Thomas, 1896. | Actual Date: | 1897 | Citation: | Proc. Zool. Soc. Lond., 1896: 1026. | Comments: | Patterson and Wood (1982) removed Chaetomyinae from the Erethizontidae and placed in the Echimyidae because this form retains deciduous premolars (an echimyid derived character) unlike all known erethizontids. Chaetomys shares characteristics of the enamel ultrastructure with taxa of the Erethizontidae (Martin, 1994b). |
