| Comment | Only limited data and bibliography provided as authors did not provide them upon request. Distribution: see map in Del Vechio et al. 2021: 2426 (Fig. 6). |
| Etymology | The specific name derives from the Greek oligos (few) and balios (spotted, dappled). The name is a reference to the smaller number of lateral trapezoidal marks on the body compared to Bothrops brazili, a name now restricted to the populations south of the Amazon River (see below). |
