GENUS Coendou
Author: | Lacépède, 1799. | Citation: | Tabl. Mamm.: 11. | Type Species: | Hystrix prehensilis Linnaeus, 1758. | Comments: | Cabrera (1961), Hall (1981), Corbet and Hill (1991), Handley and Pine (1992), Emmons and Feer (1997), McKenna and Bell (1997), Voss and Angerman (1997), Alberico et al. (1999) and Voss and da Silva (2001) included Sphiggurus in Coendou; but see Husson (1978:484-490). Woods (1984, 1993) and Nowak (1991) followed Husson (1978) and recognized Sphiggurus as distinct from Coendou. Handley and Pine (1992), Voss and Angermann (1997), and Alberico et al. (1999) concluded that Sphiggurus could not be meaningfully diagnosed as a taxon distinct from Coendou. Bonvicino et al. (2000) suggested that Coendou and Sphiggurus represent distinct lineages that have evolved by different chromosomal mechanisms. Coendou appears to be karyotypically conserved with 2n=74 and FN=82 (Bonvicino et al., 2000). Although karyotypes have been reported in only two taxa of Coendou, the chromosomal and molecular data (Bonvicino et al., 2002a) tentatively support the distinction of Coendou and Sphiggurus. |
