Abstract

Urocleidus adsimulatus n. sp., U. anchorae n. sp., and U. carolinensis n. sp. are described and Gyrodactylus gloriosi Rogers, 1968 reported from the bluespot sunfish Enneacanthus gloriosus collected in Harnett, Tyrrell, and Wake counties, North Carolina. The new species can be distinguished from closest related species by the following: Urocleidus adsimulatus from U. circumcirrus Allison & Rogers, 1970 by the morphology of the dorsal anchor, which in U. adsimulatus has a swelling at the distal end of the anchor shaft and the point formed at a distinct angle to the anchor shaft. Urocleidus anchorae from U. dispar (Mueller, 1936) and U. parvicirrus Mizelle & Jaskoski, 1942 by the size of the dorsal anchor, which in U. anchorae averages 127 µ long, and the morphology of the copulatory complex. Urocleidus carolinensis from U. udicola Allison & Rogers, 1970 by the morphology of both dorsal and ventral anchors of U. carolinensis which have swellings at the distal ends of the anchor shafts and points formed at a distinct angle to the anchor shafts. The similarity between U. adsimulatus n. sp., U. carolinensis n. sp., U. circumcirrus Allison & Rogers, 1970, and U. udicola Allison & Rogers, 1970, and affinities of the fishes harboring these parasites, are discussed.
