HELMINTHS OF 2 NATIVE FROG SPECIES (RANA-CHIRICAHUENSIS, RANA-YAVAPAIENSIS) AND ONE INTRODUCED FROG SPECIES (RANA-CATESBEIANA) (RANIDAE) FROM ARIZONA

The gastrointestinal tracts, lungs, urinary bladders, and body cavitie s of Rana catesbeiana (n = 25), Rana chiricahuensis (n = 25), and Rana yavapaiensis (N = 37) from Arizona were examined for helminths. Helmi nths representing 9 species of trematodes: Cephalogonimus brevicirrus, Glypthelmins quieta, Gorgoderina attenuata, Haematoloechus complexus, Haematoloechus longiplexus, Megalodiscus temperatus, Alaria sp., Clin ostomum sp., and an unidentified strigeid; and 4 species of nematodes: Falcaustra catesbeianae, Rhabdias ranae, Physaloptera sp., and an uni dentified ascarid were found. The helminth fauna of introduced R. cate sbeiana differed markedly from that of native ranids. Helminths of R. chiricahuensis and R. yavapaiensis represent new host records. Arizona is a new locality record for C. brevicirrus, G. attenuata, H. complex us, H. longiplexus, M. temperatus, and R. ranae.
