| Diagnosis | Diagnosis: Eutrachelophis papilio is distinguished from all other species by the following combination of characters: 15-15-15 number of dorsal scale rows; three gular scale rows, wider than long; 8 supralabials, 2-3 contacting loreal and 3-5 in orbit; 9 infralabials, 1–5 contacting anterior chinshields and 5-6 posterior chinshields; 139-145 ventrals; 68-76 subcaudals; conspicuous white butterfly-shaped ocellus on the nape; hemipenis slightly bilobed with apical disks; and 22-25 maxillary teeth subequal in size and recurved, followed by diastema and two ungrooved fangs. Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers. These details, e.g. detailed descriptions or comparisons (about 1881 characters) are available for collaborators and contributors. Please contact us for details. |
| Comment | Abundance: Known from only 6 individuals (Moraes et al.2021). Habitat: forest floor, moving near tree roots, in a terra firme forest, with large trees and streams nearby (Citeli et al. 2020). Distribution: see map in Moraes et al. 2021 for localities. |
| Etymology | The specific epithet is derived from the Latin word “papilio”, gender masculine, and noun in apposition, in reference to the butterfly-shaped white ocellus on the nape. |
