Between April 2012 and September 2013, feces from 18 green anoles, Anolis carolinensis from Arkansas (n = 14), Louisiana (n = 1), and Oklahoma (n = 3) were examined for coccidia. Two species of coccidians were found, including a new caryosporan and a new eimerian. Oocysts of Caryospora natchitochesensis n. sp. from a single A. carolinensis from Louisiana were subspheroidal to ovoidal with a smooth, yellow to brown pigmented, bi-layered wall of equal thickness (~0.3–0.7) and measured (L × W) 13.1 × 12.3 μm, with a length/width (L/W) ratio of 1.1. A micropyle and oocyst residuum were absent but a polar granule was present. Sporocysts were ovoidal and measured 10.1 × 7.4 μm, L/W was 1.4. A Stieda body (~1.0 μm) was present, but substieda and parastieda bodies were absent. The sporocyst residuum was composed of dispersed granules or globules among sporozoites. Oocysts of Eimeria robisoni n. sp. from 1 of 12 (8%) green anoles from Arkansas were ellipsoidal with a smooth, uni-layered wall (~0.4–0.5) and measured (L × W) 14.5 × 10.5 μm, with L/W ratio of 1.4. A micropyle and oocyst residuum were absent, but 1–4 (usually 2) polar granules were present. Sporocysts were subspheroidal to ovoidal and measured 5.8 × 4.9 μm, L/W was 1.2. Stieda, substieda and parastieda bodies were absent. The sporocyst residuum was composed of dispersed granules between sporozoites. None of the anoles from Oklahoma were found to be passing oocysts. This is the second time an eimerian and a caryosporan have been reported from green anoles. A summary of the coccidians of lizards of the family Dactyloidae is provided, with special emphasis on the Anolis of the United States.
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.
