The Azygiidae Looss, 1899 is a family of digeneans with a Holarctic distribution in which members of some genera mature in marine elasmobranchs while others occur only in freshwater teleosts. Some have questioned whether the marine genus Otodistomum Stafford, 1904 indeed belongs to the same family as the freshwater azygiid genera, namely Azygia Looss, 1899, Proterometra Horsfall, 1933, and Leuceruthrus Marshall and Gilbert, 1905. We present phylogenetic analyses based on mitochondrial genomes, rDNA operons, and partial cytochrome c oxidase I (Cox1) sequences from North American and Asian species that support the monophyly of Azygiidae, and placement of Azygioidea in the suborder Hemiurata, in contrast to recently published mitochondrial genome phylogenies.

Waterbirds, are one of the popular game animals and are of significant relevance to parasite spread due to their ability to fly and migrate great distances in relatively short periods of time. In Australia, however, the knowledge of parasites infecting native waterbirds is lacking with some of the last reports occurring over 50 years ago. The study aimed to characterise Echinostoma spp.

Avian Dicrocoeliidae are difficult to identify, even in their adult stages. Molecular analyses have been conducted for only a few species, complicating the accurate identification of juvenile stages. The taxonomy of the family is unresolved, and the status of many dicrocoeliid species is uncertain.

Hemiurid digeneans conspecific with Yamaguti, 1934 (the type species of the genus Yamaguti, 1934) were collected from the stomach of the daggertooth pike conger (Forsskål) off the Persian Gulf of Iran. This study aimed to provide a detailed characterization of , including measurements, illustrations and scanning electron microscopy (s.e.
