New Host and Geographic-Distribution Records for Helminth and Arthropod Parasites of the Southern Toad, Anaxyrus terrestris (Anura: Bufonidae), from Florida

We collected 18 Anaxyrus terrestris (Southern Toad) in March and May 2014 and July 2015 from Topsail Hill Preserve State Park, Walton County, FL, and examined them for helminth and arthropod parasites. Fourteen toads (78%) were infected or infested with parasites as follows: 2 (11%) with Megalodiscus temperatus, 1 (6%) with tetrathyridia of Mesocestoides sp., 3 (17%) with Cylindrotaenia americana, 2 (11%) with 3rd-stage larval Physaloptera sp., 9 (50%) with Cosmocercoides variabilis, 10 (55%) with Oswaldocruzia pipiens, and 2 (11%) with larval Hannemania hegeneri chigger mites. We observed multiple infections/infestations of helminths and/or arthropods in 7 (39%) of these hosts. Herein, we report 5 new host and 2 new geographic-distribution records.
