These four new species belong to the subgenus Biwamelania. Semisulcospira (Biwamelania) reticulataformis, sp. nov., Semisulcospira (Biwamelania) nojirina, sp. nov., Semisulcospira (Biwamelania) gamoensis, sp. nov., and Semisulcospira (Biwamelania) tagaensis, sp. nov. are newly described herein. The authorship of Biwamelania is attributed to Matsuoka and Nakamura (1981) and Melania niponica Smith, 1876, is designated as the type species of Biwamelania by Matsuoka and Nakamura (1981). Key words: Semisulcospiridae, Semisulcospira, Biwamelania, Pliocene, Pleistocene, Kobiwako Group, Japan Introduction six were already described; Semisulcospira (Biwamelania) praemultigranosa Matsuoka, 1985, Semisulcospira Boettger, 1886 is a freshwater was described from the Pliocene Iga Formation that gastropod genus widely distributed in East Asia.

ZooKeys 817: 73–93. https://doi.org/10.3897/zookeys.817.29337 Abstract The Luoxiao Mountains play an important role in maintaining and supplementing the fish diversity of the Yangtze River Basin, which is also a biodiversity hotspot in China. However, fish biodiversity has declined rapidly in this area as the result of human activities and the consequent environmental changes. Beta diversity was a key concept for understanding the ecosystem function and biodiversity conservation. Beta diversity patterns are evaluated and important information provided for protection and management of fish biodiversity in the Luoxiao Mountains.

Rivers in the Japanese archipelago, separated from the continent of Asia by about 17 Ma, have experienced an intermittent exchange of freshwater fish taxa through a narrow land bridge generated by lowered sea level. As the Korean Peninsula and Japanese archipelago were not covered by an ice sheet during glacial periods, phylogeographical analyses in this region can trace the history of biota that were, for a long time, beyond the last glacial maximum. In this study, we analyzed the phylogeography of four freshwater fish taxa, Hemibarbus longirostris, dark chub Nipponocypris temminckii, Tanakia ssp. and Carassius ssp., whose distributions include both the Korean Peninsula and Western Japan. We found for each taxon that a small component of diverse Korean clades of freshwater fishes Citation: Taniguchi, S.; Bertl, J.; migrated in waves into the Japanese archipelago to form the current phylogeographic structure of Futschik, A.; Kishino, H.; Okazaki, T.

    Effects of Trematode Infection on Metabolism and Activity in a Freshwater Snail, Semisulcospira Libertina

    DISEASES OF AQUATIC ORGANISMS Vol. 45: 141–144, 2001 Published June 20 Dis Aquat Org Effects of trematode infection on metabolism and activity in a freshwater snail, Semisulcospira libertina Kazuko Shinagawa*, Misako Urabe**, Makoto Nagoshi*** Department of Biological Science, Faculty of Science, Nara Women’s University, Kitauoyanishi-machi, Nara 630-8506, Japan ABSTRACT: Changes in the metabolism and activity of the freshwater snail Semisulcospira libertina infected with larval trematodes were studied experimentally. In snails up to 11 mm in shell width, crawling distance, feeding frequency, and the proportion of individuals located on vertical walls did not differ among snails infected with mature or immature cercariae, or uninfected snails (p > 0.05). In snails larger than 11 mm, individuals infected with mature cercariae tended to feed more frequently during the light period (p = 0.0081), but the distance they crawled and the proportion of individuals located on vertical walls did not differ, regardless of infection (p > 0.05). Infection with mature cer- cariae significantly increased the oxygen consumption rate (p = 0.016), which was measured only in the large size.

Sanguinicola ugui sp. nov. (Sanguinicolidae) is described from the blood vessels of Tribolodon hakonensis (Günther) (Cyprinidae). Azygia rhinogobii sp. nov. (Azygiidae) is described from the stomach of Rhinogobius sp. (Gobiidae, type host) and Gymnogobius urotaenia (Hilgen- dorf) (Gobiidae), and the intestine of T. hakonensis. Phyllodistomum anguilae Long and Wai, 1958, P. mogurndae Yamaguti, 1934, P. parasiluri Yamaguti, 1934 (Gorgoderidae), and Pseudex- orchis major (Hasegawa, 1935) Yamaguti, 1938 (Heterophyidae) are redescribed. The generic di- agnosis of the genus Pseudexorchis Yamaguti, 1938 is amended in part. New host and locality records are provided for 20 known species. An outline of the life cycle of Asymphylodora macro- stoma Ozaki, 1925 (Lissorchiidae) is given. A furcocystocerous cercaria, probably the cercarial stage of A. rhinogobii sp. nov., is briefly described from Sinotaia quadrata histrica (Gould) (Gas- tropoda, Viviparidae).

    www.nature.com/scientificreports OPEN Molecular phylogenetic, population genetic and demographic studies of Nodularia douglasiae and Nodularia breviconcha based on CO1 and 16S rRNA Eun Hwa Choi1,2,7, Gyeongmin Kim1,3,7, Seung Hyun Cha1,7, Jun‑Sang Lee4, Shi Hyun Ryu5, Ho Young Suk6, Young Sup Lee3, Su Youn Baek1,2* & Ui Wook Hwang1,2* Freshwater mussels belonging to the genus Nodularia (Family Unionidae) are known to be widely distributed in East Asia. Although phylogenetic and population genetic studies have been performed for these species, there still remain unresolved questions in their taxonomic status and biogeographic distribution pathways. Here, the nucleotide sequences of CO1 and 16S rRNA were newly determined from 86 N. douglasiae and 83 N. breviconcha individuals collected on the Korean Peninsula. Based on these data, we revealed the following results: (1) N. douglasiae can be divided into the three genetic clades of A (only found in Korean Peninsula), B (widely distributed in East Asia), and C (only found in the west of China and Russia), (2) the clade A is not an independent species but a concrete member of N. douglasiae given the lack of genetic diferences between the clades A and B, and (3) N. breviconcha is not a subspecies of N. douglasiae but an independent species apart from N. douglasiae. In addition, we suggested the plausible scenarios of biogeographic distribution events and demographic history of Nodularia species. Freshwater mussels belonging to the family Unionidae (Unionida, Bivalvia) consist of 753 species distributed over a wide area of the world encompassing Africa, Asia, Australia, Central and North America1, 2.
