Some digenea parasites of tunny from the coast of Rio de Janeiro State, Brazil

Abstract

Rhipidocotyle pentagonum (Ozaki, 1924) is reported for the first time in South America parasitizing Auxis thazard and in a new host Katsuwonus pelamis. Tergestia laticollis (Rudolphi, 1819) is reported for the first time in South America and in Thunnus albacares, representing a new host record. Copiatestes filiferus (Leuckart, in Sars, 1885) is recorded for the first time in Brazil and in Thunnus albacares, another new host record. Tetrochetus coryphaenae (Yamaguti, 1934) is presented for the first time in Brazil parasitizing Thunnus albacares.

Report of Enodiotrema megachondrus (Looss, 1899) Looss, 1901 (Digenea: Plagiorchiidae) in a green turtle Chelonia mydas Linnaeus, 1758 (Testudines, Cheloniidae) from Brazil

“…In addition this trematode is uncommon in the Brazilian coast. Travassos et al (1969) and Fernandes & Kohn (2014) through literature review does not report the E. megachondrus in sea turtles from Brazilian coast and the most recent analysis by Werneck and Silva (2015) and Binoti et al (2016) in juvenile of C. mydas did not report this parasite, so the occurrence of E. megachondrus is an important information about the distribution of this parasite. This note reports the fi rst occurrence of E. megachondrus in C. mydas in the South-West Atlantic Ocean, representing a new geographic distribution for the species.…”

“…microvitellatus Chattopadhyaya, 1970; E. schikhobalovae Gupta & Mehrotra 1976 and E. carettae Blair & Limpus 1982. Although these parasites are carried out at various locations in the world, on different hosts (Santoro et al, 2010), None of these species have previously been reported in hosts found in the SouthWest Atlantic Ocean (Fernandes & Kohn, 2014). The aim of this note is report the fi rst occurrence of E. megachondrus in a juvenile Chelonia mydas Linnaeus, 1758 from Brazil.…”

Two species of the fish digenean genus Rhipidocotyle Diesing, 1858 (Bucephalidae) reported for the first time from European seas

“…pentagonum has been reported not only from A. thazard, but also from various other fishes including Scomberomorus niphonius (Cuvier & Valenciennes) by Ozaki (1924Ozaki ( , 1928 off Japan, Thynnus sp. by Eckmann (1932) off the Israeli Mediterranean coast, Thunnus thynnus (L.) by Yamaguti (1938) from off Japan, Euthynnus affinis (Cantor) by Madhavi (1974) from the Bay of Bengal, E. lineatus Kishinouye by Castillo-Sanches et al (1997) off the Pacific coast of Mexico and Katsuwonus pelamis (L.) by Fernandes et al (2002) off the Atlantic coast of Brazil. R. pentagonum has been described and figured by Ozaki (1924Ozaki ( , 1928, Eckmann (1932) and Fernandes et al (2002).…”

“…R. capitata is the only species of this genus reported from A. rochei. By contrast, three Rhipidocotyle species have been reported from A, thazard: (1) R. capitata off Hawaii (Yamaguti, 1970); (2) R. pentagonum (Ozaki, 1924) from the Bay of Bengal (Madhavi, 1974) and the coast of Brazil off Rio de Janeiro (Fernandes et al, 2002); and (3) R. nagatyi Manter, 1940 from off the north-eastern coast of Africa (Szuks, 1981).…”

Registro de Copiatestes filiferus (Leukart, in Sars, 1885) Gibson y Bray, 1977 (Digenea) y Gorgorhynchus sp. (Acanthocephala) en pez marino de la costa peruana

“…El espécimen mide 17 mm de longitud y el pedúnculo 2,4 mm. La descripción de la especie ha sido hecha por Gibson y Bray (1977) incluyendo sinonimia y distribución geográfi-ca; a esta última debemos agregar, además de Perú en Sudamérica, la costa atlántica de Brasil (Fernández et al, 2002) y la del Pacífi-co en Chile, aunque Oliva (1999) lo refiere como Syncoelium filiferus. De acuerdo a Gibson y Bray (1979) la familia Syncoeliidae la integran 2 géneros: Syncoelium y Copiatestes que se diferencian por la presencia de un sinus genital en el segundo.…”
