Checklist of metazoan associated with grunts (Perciformes, Haemulidae) from the Nearctic and Neotropical regions

Using information from published articles, databases, and recent samples from the Brazilian coastal zone, a list of parasites of haemulid (grunts) fish known from the Neotropical and Nearctic regions was structured. A total of 231 species of parasites were listed totaling 775 records involving 48 hosts, distributed in 86 localities of the American Continent. Records were listed with information on hosts, habitat, distribution and new findings; a host-parasite list is also included herein.

Dichelyne (Cucullanellus) tornquisti n. sp. (Nematoda: Cucullanidae) from Corocoro Grunt, Orthopristis ruber (Cuvier, 1830) (Perciformes: Haemulidae) from Southeastern Brazil

Abstract:  Dichelyne (Cucullanellus) tornquisti n. sp. is described from the intestine of the marine fish Orthopristis ruber (Haemulidae) of Rio de Janeiro, Brazil. The new species differs from the congeners by the location of the deirids (same level) and the excretory pore (posterior) in relation to esophagus-intestinal junction and by papillae 5 to 9 not forming a subventral line. It is the first Dichelyne species described from fish family Haemulidae in the Brazilian coastal zone.

Redescription of Rhamnocercus stichospinus Seamster and Monaco, 1956 (Monogenea: Diplectanidae), Parasitic on Menticirrhus americanus (Osteichthyes: Sciaenidae) from the Coastal Zone of the State of Rio de Janeiro, Brazil

Rhamnocercus stichospinus Seamster and Monaco, 1956 (Diplectanidae) parasitic on the sciaenid fish Menticirrhus americanus from the coastal zone of the State of Rio de Janeiro, is redescribed and recorded for the first time in the South American Atlantic Ocean. The generic diagnosis of Rhamnocercus is emended to accommodate the presence of confluent intestinal ceca in R. stichospinus.

Occurrence of Clavellisa ilishae (Copepoda: Lernaeopodidae) parasitizing herrings (Actinopterygii: Clupeidae) in Brazil

The lernaeopodids are highly specialized copepods which are widely distributed worldwide. In this paper the first record of Clavellisa ilishae Pillai, 1962 in the Neotropical region is documented parasitizing Sardinella brasiliensis from coastal zone of Rio de Janeiro, Brasil.

Redescriptions of two species of Lepeophtheirus (Copepoda, Siphonostomatoida, Caligidae) parasitic on teleost marine fishes from the coastal zone of the State of Rio de Janeiro, Brazil

Two species of Lepeophtheirus Nordmann, 1832 parasitic on the ariid fish Netuma barba Lacepede, 1803, and the bothiid fish Paralichthys sp. from the coastal zone of the State of Rio de Janeiro, are redescribed and illustrated: L. bagri Dana, 1852, and L. monacanthus Heller, 1865. New junior synonyms for these species are proposed: L. marginatus syn.n., L. christianensis syn.n. and L. platensis syn.n. of L. bagri and L. unispinosus syn.n. of L. monacanthus.
