“… Hossen et al (2022b) demonstrated with cox 1 barcodes the presence of Allogastrocotyle bivaginalis both in Mediterranean waters, off Algeria (report by Bouguerche et al, 2019a , Bouguerche et al, 2019b ) and in Australian waters (Victoria) of the southwest Pacific. The authors also demonstrated the presence of Kuhnia scombri (Kuhn, 1829) and Pseudokuhnia minor (Goto, 1984) in ten locations along the coast of China (recorded by Yan et al (2016) ) and in Australian waters (Victoria) of the southwest pacific ( Hossen et al, 2022b ). Similarly, the microcotylids Microcotyle algeriensis Ayadi, Gey, Justine & Tazerouti, 2016 and M. merche Víllora-Montero, Pérez-del-Olmo, Valmaseda-Angulo, Raga & Montero, 2023 has been demonstrated to occur both in the western Mediterranean and northeast Atlantic waters ( Víllora-Montero et al, 2023 ).…”

“…Overall, the presence of Polyopisthocotylea in distinct localities is not unusual and has been previously challenged by cox 1 barcodes. Consequently, the taxonomic and geographic status of several polyopisthocotyleans has been validated (see ( Hossen et al, 2022a , 2022b ). Hossen et al (2022b) demonstrated with cox 1 barcodes the presence of Allogastrocotyle bivaginalis both in Mediterranean waters, off Algeria (report by Bouguerche et al, 2019a , Bouguerche et al, 2019b ) and in Australian waters (Victoria) of the southwest Pacific.…”

This study determines the occurrence and molecular characterisation of Monogenea from three commercially important Australian fish: Australian sardine Sardinops sagax (Jenyns), Australian anchovy Engraulis australis (White), and eastern school whiting Sillago flindersi McKay. Earlier studies have provided only morphological species identification, whereas this study combines both morphological and molecular methods. A total of 247 fish across 3 species, sourced from the New South Wales and Victorian coasts, were examined for Monogenea. A total of 187 monogenean parasites were recovered from the gills. The overall prevalence, mean intensity, and mean abundance were 34%, 2.23, and 0.78, respectively. The parasites were initially classified morphologically as three species across two families. Family Mazocraeidae was represented by Mazocraes australis Timi et al. J Parasitol 85:28–32, 1999, and family Microcotylidae by Polylabris sillaginae (Woolcock, Parasitology 28:79–91, 1936) Dillon, Hargis, and Harrises, 1983 and P. australiensis Hayward, 1996. Molecular identification of parasites was conducted through sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. The fish hosts in the present study were also barcoded (mitochondrial cox1 gene) to confirm specific identities. There was no comparable cox1 sequence available in GenBank for the parasites found in the present study. However, the phylogenetic tree clustered the monogenean species identified in this study according to their familial groups of Mazocraeidae and Microcotylidae. The presence of M. australis on E. australis and S. sagax was confirmed in this study. Polylabris australiensis was only found on S. sagax but Si. flindersi was found to be a host for both Polylabris species. This study is the first to explore the mitochondrial cox1 genes of these three-monogenean species. These findings will serve as a foundation for future monogenean research in Australian waters and elsewhere.

Monogeneans are highly host‐specific parasites infecting marine and freshwater fish. However, little information is available about the parasitic taxa within Heteraxinidae. An integrative study was performed to understand the taxonomic status of an unconfirmed heteraxinid marine species parasitizing the gill region of Acanthopagrus bifasciatus (Sparidae) from the Arabian Gulf (Saudi Arabia). Based on the morphological study, this parasite has all the generic features of the genus Kannaphallus (Heteraxinidae, Mazocraeidea). Distinct criteria that discriminated this species from other taxa of the same genus are the presence of genital spines (26–29), a short sclerotized duct in the male copulatory organ, the number of testes (mean 40, range 30–50), and clamps in the haptoral structure (45–50 in a long row and 19–22 in a short row). DNA of parasite species reported in the present study was amplified and sequenced for the nuclear large subunit of the ribosomal RNA (28S rRNA) gene and the mitochondrial cytochrome c oxidase subunit I (COI) gene. Results indicate that sequences obtained from both genes are unique and different from related sequences from the genus Kannaphallus. Morphological as well as molecular data indicate that our specimens are from a new species, and the name Kannaphallus acanthopagrusi n. sp. is suggested. This is the first report of a heteraxinid parasitizing marine sparid fish from Saudi Arabia, with unique morphological and molecular features.
