New records of Monogenoidea (Platyhelminthes) from three marine fish species from the coast of Angra dos Reis, Rio de Janeiro, Brazil

During a survey of helminth parasites, five monogenoid species were reported from marine fishes from the coast of Angra dos Reis, littoral of Rio de Janeiro State, Atlantic Ocean. A total of 810 monogenoids were collected: Pseudotagia pomadasys Hernandez-Vale, Bunkley-Williams & Williams Jr, 2016, Pseudoeurysorchis travassosi Caballero & Bravo-Hollis, 1962 in Haemulopsis corvinaeformis (Steindachner, 1868) (=Pomadasys corvinaeformis), Neodiplectanum mexicanum (Mendoza-Franco, Roche & Torchin, 2008) Domingues, Diamanka & Pariselle, 2011 and Aristocleidus hastatus Mueller, 1936 in Diapterus rhombeus (Cuvier, 1829) and Acanthocercodes bullardi Kritsky & Diggles, 2015 in Polydactylus virginicus (Linnaeus, 1758). The presence of P. pomadasys, P. travassosi and A. hastatus in the Southwest Atlantic Ocean represents a new geographical distribution for these species. Haemulopsis corvinaeformis represents a new host record for P. travassosi and A. bullardi is reported in the present paper for the first time parasitizing the gills of a polynemid in South Atlantic Ocean. The findings show that they belong to species previously recorded from the same or congeneric hosts from Central America and Mexico, representing new data on hosts and geographical records.
