| Comment | Synonymy: from Melo-Sampaio et al. 2021 |
| Etymology | The specific epithet "akerios" in the Greek means life-less. The word is related to the Greek goddess Keres, (Κῆρες) who personifies violent death and destruction. We draw a parallel, where this new species is named after the sudden disappearance in one of the main areas explored and well-studied in relation to Amazonian snakes. |
