Summary :The present work is a contribution to the systematics of Bilharziella and Dendritobilharzia. Wildfowl was killed in hunting seasons or found dead in Champagne-Ardenne region, France, and autopsied with focus on schistosomes. Seven Anas platyrhynchos (mallards), one Ardea cinerea (grey heron) and two Cygnus olor (mute swans) were parasitized by Bilharziella. One C. olor was parasitized by Dendritobilharzia. Depending on season and hosts, various morphological forms of Bilharziella suggesting several species were observed. The differences in male and female worms concerned the morphology of genital apparatus, the spination on suckers, the body size and proportions. However, the comparison of DNA sequences led to a conclusion that these forms belonged to one species, Bilharziella polonica (Kowalewski, 1895). The morphological features and the body sizes of our samples of Dendritobilharzia seemed to differ from the type species of D. pulverulenta (Braun, 1901). Nevertheless, molecular analysis confirmed identity. We hypothesize that the differences in Bilharziella and Dendritobilharzia might be linked to internal host factors (e.g. hormonal levels), and influenced by season, host, and worm age. The definition of the genera Bilharziella and Dendritobilharzia was amended. Résumé : VARIATIONS MORPHOLOGIQUES SAISONNIÈRES

“…nov. from E. gainesi in Hokkaido. The new species was at first thought to be an immigrant species due to the recent anthropogenic introduction of host animals, because the parasite showed morphological similarities to already known species from rodents of the genus Rattus [9,36,37,38,39]. However, the population genetics analysis of the parasite mtDNA suggests that the new species is originally indigenous to Hokkaido.…”

Keywords:Brachylaima ezohelicis sp. nov. Ezohelix gainesiHokkaido -3 - IntroductionLand snails are terrestrial gastropod mollusks with or without shells, and the majority are hermaphroditic pulmonates. They have been highly diversified in the Japanese Archipelago, and the resulting fauna now includes approximately 800 species in spite of its small land area [Biodiversity Center of Japan (biodic.go.jp)]. Many of them are endemic species to Japan. Such a unique situation provides advantages to study evolutionary ecology in a geographic context. However, there have been few studies done concerning host-parasite ecological relationships between Japanese land snails and their internal organisms.As concerns trematode parasites, members of the families Brachylaimidae In this study, a small number of immature brachylaimids were found from intestines of Japanese toads (Bufo japonicus formosus) captured in a forest city park in Asahikawa, Hokkaido, the northernmost island of Japan. The infection seems to be accidental because the gravid adult worms were never seen in the other toad samples. The toad is an alien species from the Kanto region of Honshu island where there are no records of brachylaimid infections in amphibians [20]. A subsequent snail survey in the city park showed that land snails of Ezohelix gainesi (Bradybaenidae) are heavily infected with both sporocysts and metacercariae. A DNA sequence identification revealed that all the immature parasites detected from the toads and the snails belong to the same species. Fully matured adults were obtained through an experimental infection of immunosuppressed mice with metacercariae from E. gainesi. Based on morphological features of the adult specimens, we propose a new species of the genus Brachylaima. In this study, an additional description of Brachylaima sp., which has already been reported from the large Japanese field mouse Apodemus specious in Hokkaido [14], was also made for comparison with the new species.
