Comments: | Name often accredited to Gray, 1821. The Hydrochoerids were included as a subfamily by Tate (1935) and Ellerman (1940) but others (McKenna and Bell, 1997; Miller and Gidley, 1918; Pocock, 1922a; Woods, 1993) have recognized them as a distinct family. Molecular data (Rowe and Honeycutt, 2002) clearly support the inclusion of Hydrochoeris within the Caviidae. Placed in the superfamily Cavioidea by Woods (1982) and McKenna and Bell (1997). |
