Vine snakes (Oxybelis) and Sharpnose snakes (Xenoxybelis) (Squamata, Serpentes) from lowlands of Bolivia, with first records of Oxybelis inkaterra for the country

Abstract

We present information on the occurrence of colubrid vine snakes (Oxybelis) and dipsadid sharpnose snakes (Xenoxybelis) from the lowlands of Bolivia. These genera have been poorly reported from Bolivia and information presented herein includes nine new record provincials from the departments of Beni, Cochabamba, La Paz, Pando, and Santa Cruz, Bolivia. Moreover, we present the first records of Oxybelis inkaterra Jadin, Jowers, Orlofske, Duellman, Blair & Murphy, 2021 from Bolivia and we extend the known range of this species by approximately 207 km (Río Sipia, La Paz) and 628 km (Campamento Guacharos, Cochabamba) southeast of the type locality (Puerto Maldonado, Peru) in South America. In addition, we present morphometric information, meristic characters, coloration pattern, ecological aspects and natural history for the three species of vine snakes (O. aeneus, O. fulgidus, O. inkaterra) and two species of sharpnose snakes (X. argenteus, X. boulengeri) from the Bolivian lowlands.
