The Savanna racer snake Erythrolamprus aenigma is found in northern Brazil, Guyana and Venezuela. Here I present the first records of this species in eastern Colombia, extending the known distribution more than 1000 km east of its nearest range.
T he Villavicencio Coralsnake (Micrurus medemi) is a Colombian endemic with a distribution centered around the type locality at Villavicencio, Meta, Colombia, at elevations of 400-1,400 m asl (Bolívar 2019;Caicedo and Lynch 2015). These semifossorial snakes are associated with surface litter in low montane forest (Campbell and Lamar 2004), where they are known to feed on South American Coffeesnakes (Ninia atrata) (Roze 1996) and probably prey on a variety of small reptiles (Campbell and Lamar 2004). Little else is known about natural history. That lack of knowledge and a very limited distribution resulted in classification as Endangered (EN) in the Colombian Red Book of Reptiles (Morales-Betancourt et al. 2015) and as Critically Endangered (CR) on the IUCN Red List (Calderon et al. 2019). Herein we provide the first accurate records for the Department of Cundinamarca (Colombia) (Fig. 1) and a new elevational record for the species.We found the first individual (Fig. 2A) on 30 May 2021 in the village of Conucos, Municipality of Guayabetal, Cundinamarca (4.20258°N, -73.82421°W) at an elevation of 1,577 m asl where cattle graze in an area dominated by grasses (Poaceae and Cyperaceae). We encountered a second individual (Fig. 2B) on 18 June 2021 in leaf litter in a forest in the village of Chirajara Baja, Municipality of Guayabetal, Cundinamarca (4.20335°N, -73.80157°W) at an elevation of 1,322 m asl. Both were recorded during visual encounter surveys (VES) (Crump and Scott 1994) and documented only with photographs. Photographic vouchers have been deposited in the Milwaukee Public Museum (MPM VZP 1043-4). We recorded a third individual (Fig.
The Lined Groundsnake (Lygophis lineatus) is distributed in Central and South America, ranging from Panamá south to Argentina (Lopes et al. 2021; Uetz et al. 2021). The diet of this species is known to include frogs, lizards, and insects (Angarita-Sierra et al. 2013; Rojas-Murcia et al. 2015; Lopes et al. 2021), and cannibalism has been reported (Escalona 2012).At about noon on 26 May 2005, we encountered a Lined Groundsnake feeding on a Caribbean Ditchfrog (Fig. 1) in the municipality of Arjona, Bolívar, Colombia. The snake initially grabbed the frog by the posterior body before swallowing it hindlimbs first. Complete ingestion took only a few minutes.Predation by Lygophis lineatus on frogs of the genus Leptodactylus has been documented (Escalona 2012; Lopes et
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
