James T. Stroud. All rights reserved. WWW.IRCF.ORG/REPTILESANDAMPHIBIANSJOURNAL T he isolated islands of Bermuda, located ca. 1,000 km east of North Carolina, USA in the Atlantic Ocean, have a rich history of non-native species introductions (see Sterrer et al. 2004). Although Bermuda supports only one endemic lizard, the Bermuda Skink (Plestiodon [Eumeces] longirostris), four species of non-native anoles have been introduced and become established over the past century (Losos 1996; Stroud et al. 2016). In the early 20th Century, Jamaican Anoles (Anolis grahami) were introduced as (ultimately unsuccessful) biological control agents of crop-destroying insects (Wingate 1965). In the 1940s, two additional non-native anoles became established. The discovery of the Antiguan Giant Anole (A. leachii), referred to locally as the “Warwick Lizard,” at the Bermuda Botanical Gardens in central Bermuda, was fol- lowed by the discovery of the Barbadian Anole (A. extremus) in extreme northwestern Bermuda (Wingate 1965; Losos 1996). Most recently, Cuban Brown Anoles (A. sagrei) have been recorded from two geographically independent locations in Bermuda, after having first been observed in 2013 (Stroud et al. 2016). Here we present the first confirmed record of a single individual of a fifth species on Bermuda, likely to be the American Green Anole (Anolis carolinensis Voigt 1832). An earlier record of a single A. carolinensis specimen captured on Bermuda in 1876 (then labeled “A. principalis,” which has since been synonymized with A. carolinensis; Verril 1902) lacks a detailed account of the event and no specimen is avail- able for assessment. On 26 March 2016, a single adult male A. carolinensis (Fig. 1) was caught by a member of the public at a cargo dock in Hamilton, Bermuda (32.292, -64.779; Fig. 2) and brought to the Bermuda Aquarium, Museum and Zoo (BAMZ). The Hamilton cargo dockyard is a heavily urbanized environment with sparse trees (Fig. 3). Despite being phenotypically simi- lar to two other established species on Bermuda (the Jamaican Anole, A. grahami, and the Barbadian Anole, A. extremus), a member of the public recognized it as different and thought it warranted capture. The captured lizard measured 65 mm SVL (173 mm total length) and weighed 6.3 g. The lizard was euthanized and accessioned into the Bermuda Natural History Museum collection (Specimen No. 2016 296 009). Representatives from the Department of Environment and Natural Resources failed to find any other individuals during INTRODUCED SPECIES Fig 1.
