“…At present, 42 species of cyclopoids have been recorded to parasitize marine fish in Brazil; seven of these (16%) belong to the family Philichthyidae, i.e., six species of Colobomatus, including the two species described herein, and one species of Leposphilus (Luque et al, 2013;Paschoal et al, 2016a). In contrast, 78 species of cyclopoids have been recorded to parasitize freshwater fish in Brazil, where in the last 2 years, five new species and two new genera have been described (Taborda et al, 2016;Narciso et al, 2019;Narciso & Da Silva, 2020). The Brazilian coastline extends for more than 7000 km, encompassing approximately 60% of the Atlantic coast of South America, and harbors one of the richest marine diversities on the planet, with approximately 1,227 species of fish recorded (Angulo et al, 2006;Froese & Pauly, 2021).…”

Two new species of parasitic copepods of the genus Colobomatus Hesse, 1873 (Cyclopoida) are proposed based on specimens collected from the squirrelfishes (Holocentridae) off the coast of Rio de Janeiro, Brazil. Colobomatus luquei n. sp. from the interorbital canals of Holocentrus adscensionis (Osbeck) can be distinguished from its closest congeners by the following combination of characters in the adult female: first to fourth thoracic somites fused, two pairs of thoracic processes, fifth pedigerous somite without processes, and process in the third abdominal somite not transpassing the margins of the caudal rami; and in the adult male: antenna with two elements in the second endopodal segment, leg 1 with three spines and three setae in the second endopodal segment, and leg 2 with three spines and three setae in the second exopodal segment. Colobomatus freirei n. sp. from the interorbital canals of Holocentrus rufus (Walbaum) can be distinguished from its closest congeners through the possession of an anterior pair of thoracic processes four times longer than the posterior pair. The two new species described herein are the first representatives of the family Philichthyidae found to parasitize fish of the order Holocentriformes.

“…Most of these copepods are found infesting the gills of freshwater actinopterygians, but some species may be attached to nostrils, tegument and urinary bladder and, less frequently, parasitizes brackish and marine fish, as well as mollusks (Boxshall & Halsey, 2004 ; Rosim et al, 2013 ; Taborda et al, 2016 ). Ergasilidae is the richest family of parasitic copepods found on fish from Brazil, on which 74 species from 18 genera have been reported (Narciso et al, 2019 ; Narciso & Da Silva, 2020 ; Narciso et al, 2020 ; Narciso et al 2021a , 2021b ; Oliveira et al, 2021 ). However, some authors affirm that such diversity is still underestimated, since only a small fraction of the Brazilian ichthyofauna has been studied for parasitic copepods (Luque et al, 2013 ; Taborda et al, 2016 ; Narciso & Da Silva, 2020 ; Paschoal et al, 2022 ).…”

Two new species of copepods assigned to the genus Acusicola Cressey, 1970 (Cyclopoida: Ergasilidae) are proposed based on post-metamorphic adult females, parasitizing the gills of two actinopterygian fish off Brazil namely, the Tripletail Lobotes surinamensis (Bloch) (Lobotidae), collected in the coastal zone of the State of Pará, near Curuçá Municipallity, and the Swordspine snook Centropomus ensiferus Poey (Centropomidae) collected in Sepetiba Bay, State of Rio de Janeiro, Brazil. Acusicola iamarinoi n. sp. parasite of L. surinamensis , differs from its closet congeners based on the first segment of the antennule armed with 10 setae, the presence of a maxillule armed with four elements and a pair of blunt processes dorsally on the fourth pedigerous somite. Acusicola pasternakae n. sp. , collected from C. ensiferus , can be distinguished from its closest congeners based on the membranous sheath of the first endopodal segment of antenna with horizontal marks, the first segment of the antennule armed with 11 setae and a spine on the last exopodal segment of leg 2. This is the first report of representatives of Acusicola parasitizing fish of the families Lobotidae and Centropomidae as well as new geographical records of the genus in the coast of State of Pará and in Sepetiba Bay, Brazil.
