Summary: The diversification of tapeworms of the subfamily Gangesiinae, parasites of catfishes, is evaluated using molecular and morphological evidence. The Indomalayan region appears to be the ancestral homeland and a major center of diversification of these tapeworms, with range expansions in western and northern parts of Eurasia and Africa.

Summary: A new species of Tatia from the rio Tapajos in Brazil is described. This new species is distinguished from others based on morphological characteristics, color pattern, and feeding habits. It is a nocturnal fish that feeds on insects on the water surface and is likely endemic to the rio Tapajos basin.

Summary: The genus Synapturanus includes three new species of fossorial frogs, differentiated from congeners by external morphological, acoustic, and osteological traits. The species exhibit an increase in fossorial habits in the easternmost species, while the relatively conserved morphology of the posterior body suggests fossoriality mainly involves the anterior part. The fusion of tarsal bones in western clade species may indicate locomotory adaptation to more epigean habits.

Summary: Liobagrus huaiheensis, a new species of catfish, is distinct from other Liobagrus species in China due to its unique combination of characteristics, such as serrations on the pectoral-fin spine, number of anal-fin rays, and position of the anus close to pelvic-fin insertion.

Summary: The study revealed a strong genetic structure among populations of B. xanthellus within its distribution range, with potential isolation of populations at the downstream limit due to the impoundment of the Middle Xingu channel for the Belo Monte hydroelectric dam. Therefore, future conservation plans need to take into account the genetic diversity of B. xanthellus throughout its range.

Summary: Phenotypic polymorphism is rarely observed in free-living stages of parasites, but a unique case of somatic polymorphism in conspecific cercariae of Trichobilharzia sp. peregra was described here. Two distinct size morphs were identified, with small individuals being the normal phenotype in snail populations. The causes and consequences of generating a larger alternative phenotype in the parasite infrapopulation were discussed in the context of transmission ecology.

Summary: This study investigated the daily cercarial emergence rhythms of bird schistosomes in a subarctic lake and found a circadian rhythm with the highest emergence during the morning hours. These patterns were independent of the photo- and thermo-period regimes and showed relatively high production of cercariae at low temperatures.

Summary: A new species of tapeworm, Bothriocephalus kupermani n. sp., is described based on morphological and molecular data. It is found to mainly parasitize pumpkinseed and green sunfish. The new species differs from its North American congeners mainly in the shape of its scolex and the presence of vitelline follicles in the ovarian and uterine areas. It appears to be associated with Lepomis sunfishes.

The genus is distinct from other proteocephalid genera and its phylogenetic relationships have not been resolved. Other similar species and a list of cestode parasites reported from bowfin are also discussed.

Summary: Tapeworms account for one-third of the total tapeworm species diversity in fishes, with elasmobranchs and teleosts being the main hosts. Significant progress has been made in understanding their species diversity and host associations in the last 20 years. Molecular data have greatly contributed to the classification of fish tapeworms.

Summary: We provide the first evidence of EV secretion across all stages of the tapeworm Schistocephalus solidus using a laboratory life cycle model. EV-like bodies were observed in all examined stages, including hexacanths, procercoids, plerocercoids, and adults. We also describe novel tegumental structures potentially involved in EV biogenesis and the presence of elongated EVs similar to other parasite species.

Summary: For the past 80 years, tilapia have been globally translocated for aquaculture, with production recorded in over 124 countries. Of the 7 million tonnes of tilapia produced, 79% comes from countries outside their natural range. Tilapias carry numerous parasites, and this review provides a summary of over 2500 host-parasite records and more than 820 recorded tilapia translocations. The study highlights the significant pathogens that pose a threat to tilapia health and identifies the risks of parasite translocation as aquaculture industries expand.

Summary: This study analyzed the partial sequences of the 28S ribosomal RNA gene of seven species of Cosmetocleithrum, providing insights into the evolutionary relationships and classification of this parasite genus. The results revealed that Cosmetocleithrum is an evolutionary recent group composed of two well-defined lineages. However, the search for defining characteristics within Cosmetocleithrum remains challenging.

The new genus is most similar to Lucknowia in body shape, but differs in ovary shape and vitelline follicles. Molecular data support the erection of the new genus and distinguish it from Bovienia in scolex shape and vitelline follicle position.

Summary: The caryophyllidean genus Archigetes is unique in its ability to mature in invertebrate hosts and has been found in both non-native common carp and native freshwater fishes in North America. A molecular study has identified three new species and provided a key for identification. Archigetes and Paraglaridacris differ most noticeably in the structure of the ovary.
