Ligictaluridus posthon n. sp. (Monogenea: Ancyrocephalidae) from Noturus flavus Rafinesque (Siluriformes: Ictaluridae) in Ontario, Canada
As a result of further studies following the review of the genus Ligictaluridus by G. J. Klassen and M. Beverley-Burton, we propose Ligictaluridus posthon n. sp. for ancyrocephalid monogeneans found on Noturus flavus (Siluriformes: Ictaluridae) taken in Ontario. Ligictaluridus posthon is most similar to the type species, L. pricei (Mueller, 1936) Beverley-Burton, 1984 but is distinguished by a stouter penis, with a diameter to length ratio of ~1:6 (~1:18 in L. pricei), larger hamuli, and an apparent specificity for stonecats (Noturus flavus).
