Abstract
Actinocleidus oculatus (Mueller, 1934), the type species of Actinocleidus Mueller, 1937, and A. recurvatus Mizelle and Donahue, 1944 (Monogenea: Ancyrocephalinae) from the gills of Lepomis gibbosus L. (pumpkinseed) in Ontario, Canada, are redescribed with details of their internal anatomy as well as the sclerotized components of the haptor and copulatory complex. A revised generic diagnosis incorporating features of the reproductive system is presented.
