Polyphyly of the Dinurinae Looss, 1907 (Digenea: Hemiuridae) and resurrection of the Mecoderinae Skrjabin & Guschanskaja, 1954 based on novel collection of Tubulovesicula laticaudi Parukhin, 1969 from marine elapid snakes in Sri Lanka

Morphological and molecular characterization ofStomachicola muraenesocisYamaguti, 1934 (Digenea: Hemiuridae) from the daggertooth pike congerMuraenesox cinereus(Forsskål)

“…The Stomachicolinae was synonymized with the Dinurinae by Gibson and Bray (1979), and this synonymy was accepted by Gibson et al (2002) and Madhavi and Bray (2018). Martin et al (2023) transferred the previously recognized dinurines without permanent sinus-organ to the Mecoderinae Skrjabin and Guschanskaja, 1954(Mecoderus Manter, 1940, Tubulovesicula Yamaguti, 1934, Stomachicola and Allostomachicola). A total of 25 species of Stomachicola have been described to date.…”

“…Based on gross morphology, Stomachicola/Allostomachicola belong to the Dinurinae (see Gibson and Bray, 1979). Recently, Martin et al (2023) resurrected the Mecoderinae to accommodate the dinurines with a temporary sinus-organ (Allostomachicola, Mecoderus, Stomachicola and Tubulovesicula) and restricted the Dinurinae for dinurines representing a permanent sinus-organ (Dinurus, Ectenurus, Erilepturus, Paradinurus and Qadriana). Morphological examination of our specimens, however, revealed that the sinus-organ is of permanent type in Stom.…”

Parasaturnius maurepasi n. gen. et n. comb. (Digena: Bunocotylidae) from the stomach of the silver mullet, Mugil curema (Perciformes: Mugilidae) in coastal lagoons of northern Yucatán, Mexico

“…Nevertheless, in recent molecular phylogenetic analyses, these subfamilies of Bunocotylidae were yielded as paraphyletic (Louvard et al, 2022 ; Faltýnkova et al, 2022 ). In a recently published study, Martin et al ( 2023 ) also suggested that Bunocotylidae was paraphyletic relative to the Hemiuridae sensu stricto and the Lecithasteridae sensu stricto . Based on the latter arguments, the current concept of Bunocotylinae contains only 14 species classified in three genera, Bunocotyle Odhner, 1928, with four species; Saturnius Manter, 1969, with nine; and Robinia Pankov, Webster, Blasco-Costa, Gibson, Littlewood, Balbuena & Kostadinova, 2006 , with only one species (Pankov et al, 2006 ; Blasco-Costa et al, 2008 ; Louvard et al, 2022 ; Faltýnkova et al, 2022 ).…”

“…Members of Bunocotylidae Dollfus, 1950 are a relatively diverse group of trematodes with approximately 149 species infecting the gastrointestinal tract (mainly the stomach) of marine and estuarine fishes around the world (Atopkin et al, 2020 ; WoRMS, 2023 ). The taxonomic history and classification of the family has been rather controversial (Pankov et al, 2006 ; Sokolov et al, 2019 ; Louvard et al, 2022 ; Martin et al, 2023 ). Using a molecular phylogenetic analysis based on 28S rDNA, Atopkin et al ( 2020 ) showed that Bunocotylidae was constituted by four subfamilies, namely Bunocotylinae Dollfus, 1950 with three genera, Hysterolecithinae Yamaguti, 1958 with four, Opisthadeninae Yamaguti, 1970 with five, and Quadrifoliovariinae Yamaguti, 1955 with three genera (see Worms, 2023 ).…”

A new species of Siphoderina Manter, 1934 (Digenea: Cryptogonimidae) infecting the Dory Snapper Lutjanus fulviflamma (Teleostei: Lutjanidae) from the east coast of South Africa

“…Parasitological assessment of fishes from Sodwana Bay on the east Coast of South Africa yielded samples of several trematode species, including a species of cryptogonimid from the Dory Snapper, Lutjanus fulviflamma (Forsskål) (Lutjanidae). The Cryptogonimidae Ward, 1917, is a large trematode family with 79 recognised genera and over 280 recognised species (WoRMS, 2023 ), which, as sexual adults, infect a wide range of (primarily demersal, predatory) freshwater and marine fishes, crocodilians and some snakes and amphibians (Martin et al, 2023 ; Miller & Cribb, 2008b ). Despite their widespread distribution and expansive host range, this is the first cryptogonimid species to be reported from South Africa.…”
