abstract
2015 The Helminthological Society of Washington. Between June 2012 and July 2013, 43 slender madtoms (Noturus exilis) and 21 Black River madtoms (Noturus maydeni) were collected from 4 counties of northern Arkansas and examined for helminths. Eleven (26%) slender madtoms were infected with digenean trematodes, including 3 (7%) with metacercaria of Posthodiplostomum minimum, 3 (7%) with Alloglossidium sp., and 7 (16%) with Plagioporus sp.; a single (5%) Black River madtom was infected with Caecincola sp. We document new host records for each of these 4 helminths. Notable among these new host records are new distributional records for Caecincola sp. To our knowledge this represents the first report of any helminth from N. exilis and N. maydeni.
