Abstract

ABSTRACT The rare Amazonian snake Eutrachelophis papilio is known from only five individuals, from four localities, belonging to its type-series, the more recent collected over 10 years ago. Here, we expand its distribution and describe its color in life for the first time. We also provide an estimate of its distribution area using the minimum convex polygon method and identify the values of anthropic pressure within its known distribution range with the Human Footprint Index. The new occurrence is located 291 km from the nearest known locality and its distribution is associated with pristine forests. Considering its rarity, and the absence of demographic and biological data, we suggest that the species should be classified as Data Deficient by IUCN criteria.

Highlights

The rare Amazonian snake Eutrachelophis papilio is known from only five individuals, from four localities, belonging to its typeseries, the more recent collected over 10 years ago
The snake genus Eutrachelophis was described based on two species from western and middle Amazonia, Eutrachelophis bassleri Myers and McDowell, 2014 and Eutrachelophis steinbachii (Boulenger, 1905), and a third unnamed Amazonian taxon related to E. bassleri
Zaher and Prudente (2019), based on hemipenis morphology, established the genus Baliodryas to accommodate Eutrachelophis steinbachi, which is restricted to Bolivia and southeastern Brazil. They redefined Eutrachelophis to accommodate two rare species, E. bassleri and the new Eutrachelophis papilio Zaher and Prudente 2019, which corresponds to the third taxon discussed by Myers and McDowell (2014)
