The Cyathocotylidae is a globally distributed family of digeneans parasitic as adults in fish, reptiles, birds and mammals in both freshwater and marine environments. Molecular phylogenetic analysis of interrelationships among cyathocotylids is lacking with only a few species included in previous studies. We used sequences of the nuclear 28S rRNA gene to examine phylogenetic affinities of 11 newly sequenced taxa of cyathocotyl...

Three species of

Lyperosomum sarothrurae Baer, 1959 is a rare dicrocoeliid described based on a single specimen from Belgian Congo, now Democratic Republic of the Congo, and never reported again. The original description lacked several important details of the species morphology. This work provides morphological redescription of Lyp. sarothrurae based on specimens from Kibale National Park, Uganda which is about 200 kilometres from the type lo...

The plagioporine opecoelids Helicometra fasciata (Rudolphi, 1819) Odhner, 1902, and Macvicaria crassigula (Linton, 1910) Bartoli, Bray, and Gibson, 1989 have been reported from fishes in expansive geographic regions, disjointed from their type localities. New material of M. crassigula was collected from near its type locality as well as specimens resembling Helicometra fasciata sensu lato from three triglids in the Gulf of Mex...
