Trematode diversity in freshwater snails from a stopover point for migratory waterfowls in Hokkaido, Japan: An assessment by molecular phylogenetic and population genetic analyses

Life history strategies of Cotylurus spp. Szidat, 1928 (Trematoda, Strigeidae) in the molecular era – Evolutionary consequences and implications for taxonomy

“…One branch consists of clustered isolates determined by Heneberg et al (2018) as C. syrius ( C. syrius C) obtained from Cy. olor from the Czech Republic; sequences derived from metacercariae described by Nakao and Sasaki (2021) as Cotylurus sp. A collected from R. auricularia from Japan, and four isolates generated in this study from tetracotyles collected from lymnaeid and planorbid snails ( Fig.…”

“…2 ). The second branch within lineage II consists of sequences obtained from sporocysts sampled from snails ( R. auricularia ) in Japan, identified by Nakao and Sasaki (2021) as Cotylurus sp. B ( Fig.…”

“…Recently, Gordy and Hanington (2019) , in results of molecular analyses of cercariae of Cotylurus from freshwater ecosystems in Canada, reported the occurrence of several new lineages. Additionally, Nakao and Sasaki (2021) , during molecular studies of metacercariae and sporocysts collected from Radix auricularia sampled from Nagayama-Shinkava River (Hokkaido, Japan), also revealed four different lineages within Cotylurus spp. These data strongly suggest cryptic diversity within this taxon.…”

“…Moreover, the mentioned studies affirm unclear taxonomic position type-species of Cotylurus , i.e., C. cornutus (Rudolphi, 1809) Szidat, 1928, which possibly indicates that this taxon de facto consists of a complex of species, as suggested earlier by Zazornova (2004 , 2010) . Recently, Locke et al (2018) , based on morphological features of adult trematode and molecular data, described a new species of Cotylurus , C. marcogliesei Locke et al, 2018 , while other molecular analyses based on different larval stages ( Gordy and Hanington, 2019 ; Nakao and Sasaki, 2021 ) reported the occurrence of several new molecular lineages within this genus. These data clearly proved that real species richness and the status of particular species within Cotylurus should be recognised as still far from being resolved and requiring further detailed morphological, molecular, and phylogenetic studies.…”
