SPECIES Proechimys guyannensis
| Author: | E. Geoffroy, 1803. | | Citation: | Cat. Mamm. Mus. Nat. Hist. Nat.: 194. | | Common Name: | Guyenne Spiny-rat | | Type Locality: | French Guiana, Cayenne. | | Distribution: | SC Venezuela, the Guianas, southward to C Brazil. | | Status: | IUCN – Lower Risk (lc) as P. warreni. | | Comments: | Hershkovitz (1948a) resurrected guyannensis E. Geoffroy, 1803 for this species as this name antedates cayennensis. Patton (1987) included cherriei, roberti, vacillator, oris, warreni, boimensis, arescens, riparum, and arabupu, but suggested that taxa from south of the Amazon were likely a different species from those to the north. Weksler et al. (2001) confirmed this opinion on morphological, karyotypic, and molecular grounds, and showed that P. roberti was the best name to apply to that species south of the Amazon. Husson’s (1978) recognition of warreni as a species separate from guyannensis was based on his mistaken application of the latter name to the species P. cuvieri (see Voss et al., 2001). However, it remains likely that more than a single species is included in the geographically restricted view of guyannensis presented here. Karyotype has 2n=40 and FN=54 (Reig et al., 1979). |
