“…The authors placed the species in Biacetabulum because of the anterior extent of the uterus far anterior to the cirrus-sac and the presence of two acetabulum-like loculi on the scolex. Scholz and Oros [ 48 ] recognised this species as valid, but Uhrovič et al [ 56 ] questioned its generic assignment. However, B. tandani is provisionally retained in Biacetabulum until new material is available.…”

“…Recent studies on North American caryophyllideans have revealed high diversity of these tapeworms, previously only partly described. Two new genera were erected and nine new species of the genera Biacetabulum Hunter, 1927, Promonobothrium Mackiewicz, 1968 and Isoglaridacris Mackiewicz, 1965 described [ 37 , 39 , 40 , 49 , 54 – 56 ]. In the present paper, three new species of the enigmatic Archigetes are described from catostomid fishes from the southern United States (USA).…”

The caryophyllidean genus Archigetes Leuckart, 1878 is unique among all tapeworms in that its species can mature in invertebrate hosts (Oligochaeta), i.e., have a monoxenic (direct) life cycle. All five species were described as progenetic plerocercoids in oligochaetes and two of them also as adults from cypriniform fishes. Two species, A. sieboldi Leuckart, 1878 and A. iowensis Calentine, 1962, were found in North America in non-native common carp (Cyprinus carpio). A molecular study of caryophyllideans from the southern United States has revealed the occurrence of three new species in native freshwater fishes (Catostomidae, Ictiobinae): Archigetes loculotruncatus n. sp. from Ictiobus bubalus, I. niger and Carpiodes cyprinus is the largest representative of the genus and differs by a loculotruncate scolex. Archigetes megacephalus n. sp. from Ictiobus niger, I. bubalus and I. cyprinellus is characterised by a prominent, bothrioloculodiscate scolex. Archigetes vadosus n. sp. from I. bubalus is typified by a globular scolex with very shallow loculi; it differs from the closely related A. sieboldi in the shape of the body, with a distinct neck region and a scolex wider than the remaining body. Archigetes iowensis Calentine, 1962 becomes a junior synonym of Paraglaridacris limnodrili (Yamaguti, 1934). The generic diagnosis of Archigetes is amended and a key to identification of North American taxa is provided. Species of Archigetes and Paraglaridacris differ from each other most conspicuously in the structure of the ovary, which is follicular in Archigetes versus compact in Paraglaridacris.
