| Comment | Habitat: sandy soil, among open lowland rainforest, locally characterized by the babaçu palm tree. Morphology: This species is one of ~20 species of Amphisbaena with two precloacal pores (Ribeiro et al. 2019). |
| Etymology | The specific epithet filiformis is formed from the Latin words filum (= thread) and forma (= shape) in reference to the slender body shape characteristic of the new species. |
