    Abstract:
    PURPOSE: In this study we describe a new species Microcotyle tazeroutii n. sp. (Monogenea: Microcotylidae) found on the gills and operculum of the boarfish Capros aper (Caproidae) off the Algerian coast of the Western Mediterranean. METHODS: Monogeneans were observed alive or recently dead on the operculum and gills using a dissecting microscope, measured and drawn for morphological study. Furthermore, a molecular analysis was conducted using a partial fragment of the mitochondrial cytochrome c oxidase subunit 1 (cox1) of two specimens of monogeneans and a tissue sample of the fish's gills in which the parasites were found to confirm the identity of fish. RESULTS: The new species Microcotyle tazeroutii n. sp., exhibits a combination of morphological features that differentiate it from all other known species within the genus, such as the shape and the size of body, the haptor length, the number and the size of clamps and testes, the number of spines of the genital atrium and the size of eggs. Additionally, a molecular analysis of the mitochondrial cytochrome c oxidase subunit 1 (cox1 gene) revealed significant interspecific differences between Microcotyle tazeroutii n. sp. and previously published sequences of other Microcotyle species. CONCLUSION: The morphological and molecular analyses revealed that Microcotyle tazeroutii n. sp. has unique characteristics that distinguish it from all previously identified species and confirmed the presence of Microcotyle within the Caproidae family for the first time.
