G iven their high population densities and protein intake, which are the result of their efficiency in converting ingested energy into biomass (Wells 2007), amphibians represent an important food resource for various groups of vertebrates and invertebrates.Among the groups of invertebrates that engage in anurophagy are flatworms, annelids, gastropods, arachnids, crustaceans, and insects (Wells 2007).Regarding vertebrates, various records indicate that all groups consume amphibians, including other amphibians (Wells 2007; Sierra-Rueda and Acosta-Ortiz 2020).Likewise, eggs, larval, juvenile, and adult amphibians often are prey of snakes, with amphibians being one of the main items in the diets of some species (e.g., Elaphe quadrivirgata, Thamnophis sirtalis, Thamnodynastes strigatus) (White and Kolb 1974;Bernarde et al. 2000;Wells 2007;Mori and Nagata 2016).The Brown-banded Watersnake, Helicops angulatus (Linnaeus 1758), is a semiaquatic snake that is widely distributed in South America with records in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Trinidad, and Venezuela (Nogueira et al. 2019).This snake usually inhabits areas with little human disturbance but also occupies disturbed habitats, where it can be seen in lotic and lentic bodies of water, such as ponds for fish production and temporary pools formed after rains (Martins and Oliveira 1998; Ford and Ford 2012;Acosta-Ortiz and Pardo-Moreno 2019).Due to its semi-aquatic habits, the diet of this snake is comprised mainly of animals associated with bodies of water, such as fish and anurans, although it also may include lizards and invertebrates (Martins and Oliveira 1998;Teixeira et al. 2017;Acosta-Ortiz et al. 2020).However, despite being a frequently encountered and widely distributed species, relatively few dietary records exist for H. angulatus.Herein we present a review of publications addressing the diet of H. angulatus in which anurans were reported as prey.We conducted searches using the keywords "Helicops angulatus diet" in Google Scholar and ResearchGate and reviewed the first 200 publications in each search engine and the literature cited in those publications.We prepared a list of the documented species, adjusting for taxonomic changes according to Frost (2021).In addition, we report three species of anurans for the first time as prey of H. angulatus in natural conditions, constituting the first documented records for Bolivia, French Guiana, and Suriname.We found descriptions of 22 species of anurans reported as prey items of H. angulatus (Table 1).The families with the highest number of prey species were Hylidae and Leptodactylidae, with 14 of the 22 species recorded.The genus with the greatest number of species was Rhinella, with six of the 22 species.Eighteen of the 23 available records were from Brazil.In one record from Colombia, Acosta-Galvis et al. ( 2022) reported Leptodeira annulata preying on Elachistocleis tinigua; however, according to the image presented with this record, the predator was H. angulatus.
