Estudos de cestóides de peixes do Brasil

Abstract

Os autores iniciam com este trabalho um estudo sistemático de determinação dos cestóides de peixes depositados na Coleção helmintológica do Instituto Oswaldo Cruz. São referidas ou descritas as seguintes espécies e seus hospedeiros: Schizochoerus liguloideus (Diesing, 1850) e Nesolecithus janicki Posche, 1922, ambas de Arapaima gigas (Cuvier), (piracuru); Gyrocotyle meandrica Herrera, 1946, de Callorhynchus callorhynchus (L.), (quimera); Acanthobothrium dasybati Yamaguti, 1934 e Pterobothriidae não identificado, de uma arraia não determinada; três tipos larvares de trypanorrhyncha e um de Proteocephalidea, de Cynoscion striatus (Cuv.) e C. leiarchus (pescadinha); Proteocephalus jandia Woodland, 1934, de um bagre não determinado. Monticellia siluri (Fuhrmann, 1916) e Amphoteromorphus praeputialis sp. n. de Cetopsis caecutiens e Nomimoscolex magna sp. n. de Pimelodus clarias (mandi).<br>The authors start, with this note, a systematic study for determination of cestodes of fishes of the Helminthological Collection of the Instituto Oswaldo Cruz.

Cestodes in South American freshwater teleost fishes: keys to genera and brief description of species

“…(1974). CHAMBRIER & VAYCHER (1997) reexamined the type material of this species and concluded that is a composite species, specimens of Prateocephalus mixed with Monticellia; they proposed the name Monticellia magna (Rego, Santos & Silva, 1974) comb.n., but they failed to name the Proteocephalus specimens.…”

“…Synonyms: Monticellia siluri (Fuhrmann, 1916) Woodland, 1925. FREZE (1965 gives "Corallobothriurn siluri (Fuhrmann, 1916), Harwood, 1933" as REGO et a!. (1974), BROOKS & DEARDORFF (1980).…”

“…Brooksiella gen.n. is created for Amphoteromorphus praeputialis Rego, Santos & Silva, 1974 and Nomimoscolex magna Rego, Santos & Silva, 1974, previously species inquirenda, is transferred to the genus Proteocephalus.…”

Preliminary phylogenetic analysis of subfamilies of the Proteocephalidea (Eucestoda)

“…The analysis was based on critical observations of features in most proteocephalidean genera studied by the present authors: A.A. Rego and A. de Chambrier in South America (see Rego et al, 1974;de Chambrier & Vaucher, 1984Rego, 1987Rego, , 1991Rego, , 1994de Chambrier, 1987de Chambrier, , 1988de Chambrier, , 1989ade Chambrier, ,b, 1990Rego & Pavanelli, 1990de Chambrier et al, , 1996de Chambrier & Paulino, 1997;de Chambrier & Rego, 1994Scholz et al, 1996) and V. Hanzelová & T. Scholz in the Holarctic (Scholz, 1989(Scholz, , 1991(Scholz, , 1993Scholz & Ergens, 1990;Hanzelová & Spakulová, 1992;Hanzelová & Scholz, 1992Scholz & Cappellaro, 1993;Scholz & Hanzelová, 1994;Hanzelová et al, 1995a,b;Scholz et al, 1995Scholz et al, , 1997.…”

Trypanorhynch Cestodes of Commercial Fishes from Northeast Brazilian Coastal Waters

“…Further investigations have been carried out at the subtropical Southwest Brazilian coast (Mendes 1944, Rego et al 1974, Pissaia Saciloto 1980, Pereira et al 1982, Carvajal & Rego 1983, São Clemente 1982, 1986a,b, São Clemente & Gomes 1989a,b, 1992, São Clemente et al 1991. However, all are observations on only one or a few parasite species and Palm (1995) gave no data concerning parasite abundance and prevalence of infestation.…”
