Dasypus guianensis is an armadillo described after populations on the Guiana Shield were separated from a close relative. The original paper combined genetic data and museum-specimen morphology and places the range from northern Brazil through the Guianas to eastern Venezuela.
It has a long snout and a hard dorsal carapace with flexible bands. The species description also compares skull and carapace shape with those of related armadillos.
The specialist group reports it in lowland primary forest, secondary growth, and moist savanna, as well as some rural gardens and urban settings. Activity is mainly crepuscular and nocturnal.
An extinction-risk assessment has not been added yet.
