| Author: | Moojen, 1948. | | Citation: | Univ. Kansas Publ., Nus Nat. Hist., 1(19): 379. | | Common Name: | Gracile Atlantic Spiny-rat | | Type Locality: | Brazil, Espirito Santo, Santa Teresa, Floresta da Caixa Dagua (19o55’S, 40o36’W). | | Distribution: | South bank of River Doce, Espírito Santo southward to Teresopolis, Rio de Janeiro (SE Brazil). | | Comments: | Recognized as a subspecies of iheringi by Moojen (1948) and Pessôa and Reis (1996). Lara and Patton (2000) elevated gratiosus to a species, retained bonafidei as a subspecies of gratiosus, and suggested that panema was not morphologically distinct from gratiosus. Karyotype has 2n=56 and FN=108 (Pessôa and Reis, 1996). |
