HELMINTHS OF THE WESTERN LESSER SIREN, SIREN-INTERMEDIA NETTINGI (CAUDATA, SIRENIDAE), FROM ARKANSAS

Sixteen juvenile and adult western lesser sirens, Siren intermedia net tingi Goin, 1942, were collected from 2 counties in Arkansas and exami ned for endoparasites. Eleven (69%) sirens harbored 1 or more parasite s, including 1 (6%) with Diplostomum sp. metacercariae, 9 (56%) with P roteocephalus sireni, 1 (6%) with larval Capillaria sp., and 2 (13%) w ith Falcaustra chabaudi. New locality records are documented for P. si reni and F. chabaudi, and new host records are reported for Diplostomu m sp. and Capillaria sp. The histopathology of the larval Capillaria i ntegumental infection is described in the new host. A summary is provi ded on helminths of Siren spp.
