Redescription of Gibsoniela mandube (Woodland, 1935) (Cestoda: Proteocephalidea), a parasite of Ageneiosus brevifilis (Pisces: Siluriformes), and reappraisal of the classification of the Proteocephalideans

The proteocephalid species Gibsoniela mandube (Woodland, 1935) from the siluriform fish Ageneiosus brevifilis from rio Paraná, is redescribed. This species was originally described from the same species of fish from the Amazon. The genus Gibsoniela Rego, 1984 is redefined and confirmed in the Monticeliidae. Comments are made on the relationships of the proteocephalid and monticelliid subfamilies

Esparganose em alguns vertebrados do Brasil: dificuldades na identificaçao das espécies de Luheella (Spirometra) / Sparganum in some brazilian vertebrates: problems in the identification of species of Luheella (Spirometra)

Sparganum in some Brazilian vertebrates. Problems in the identification of species of Luheella (Spirometra) - Some species of Amphibia and Reptilia are listed as new hosts of spargana, from material deposited in the Helminthological Collection of Oswaldo Cruz Institute. It is discussed the difficulties in identifying the larvae (Sparganum) and also the identification of adults of Luheella species from South America. The histopathology induced by spargana in the liver of a species of Amphibia is briefly described

Novas espécies de cestóides proteocefálideos: parasitas de peixes näo siluriformes / New species of proteocephalid cestoda in non siluriform fishes

Espécies de peixes näo siluriformes dos gêneros Serrasalmus, Geophaghus, Hoplias, Rhaphiodon e Salminus, foram encontrados parasitados por cestóides proteocefalídeos. Estes vermes eram considerados como parasitas quase que exclusivos de siluriformes, principalmente Pimelodidae. Säo descritas três novas espécies de vermes, Proteocephalus serrasalmus sp.n., Proteocephalus ocellatus sp.n. e Nomimoscolex matogrossensis sp.n., além de assinaladas duas espécies já conhecidas em novos hospedeiros, respectivamente, Choanoscolex abscissus (Riggenbach, 1896) em Rhaphiodon vulpinus Agassiz e Monticellia coryphicephala (Monticelli, 1891) em Salminus spp. Säo feitos comentários sobre o encontro de proteocefalídeos em peixes siluriformes e näo siluriformes e é dado um quadro da distribuiçäo das famílias de peixes e de proteocefalídeos na América do Sul

Cestóides proteocefalídeos de "cachara", Pseudoplatystoma fasciatus (L. ) (Pisces, Pimelodidae) de Mato Grosso / Proteocephalid cestodes from Pseudoplatystoma fasciatus (L. ) (Pisces, Pimelodidae) from Mato Grosso State, Brazil

The author describes three species of protcocephalid cestodes from the Pimelodid fish, Pseudoplatystoma fasciatus (L.) from rivers of Mato Grosso, Brazil: Nomimoscolex lopesi sp. n., Peltidocotyle rugosa Diesing, 1850 and Spatulifer rugosa (Woodland, 1935). P. rugosa is for the first time referred in this fish species. One hyperparasite nematode specimen was found in a strobila of S. rugosa.
