Pentastomiase em roedor da Bahia, identificação de Porocephalus larvares

Foram recentemente descritas ninfas de pentastomídeos em roedor cricetídeo, Zigodontomys pixuma, identificadas erroneamente como pertencentes à espécie Armillifer moniliformis. O presente trabalho sugere tratar-se de Porocephalus,possivelmente P.crotali (Humboldt, 1808)

Current state of knowledge of Cestodes from Neotropical freshwater fishes and rays

The author analyses the distribution of Cestodes in freshwater fishes and rays in Neotropic. Nearly one hundred and twenty species of cestodes from five orders and one subclasse are known in Neotropical region, especially from Brazilian rivers. Proteocephalidea is the principal Order in number of species. These are parasites of freshwater teleosts. Tetraphyllidea species are found in freshwater sting rays of family Potamotrygonidae. In these rays were also referred a species of Trypanorhyncha, Paroncomega araya. The Pseudophyllidea Senga sp. and cysticercoid larvae of the Cyclophyllidea, Valipora campylancristrota, were also referred in teleost, besides proteocephalids. From carps, Cyprinus carpia, it was found specimens of Caryophyllidea. Finally, two cestodarian species, Nesolecithus janicki and Schizochoerus liguloideu, are found in primitive osteoglossid fishes,Arapaima gigas, from the Amazon

A new classification of the Cestode order Proteocephalidea Mola

The morphology, ontogeny, life-cycles and distribution of species of the Order Proteocephalidea (Cestoda), is discussed. A brief historic of the classifications is presented. The actual scheme of taxonomy of WOODLAND (1924-1935) is criticicized and a new classification for the group is proposed. The phylogenetic uniformity of Proteocephalideans is reestablished with this classification. The genera of Monticelliidae (sensu Woodland) are transferred to the subfamilies Proteocephalinae and Corallobothriinae. Only one family is accepted in the Proteocephalidea. Proteocephalidae La Rue. 1911: with five subfamilies: Proteocephalinae. Corallobothriinae. Sandonelliinae. Gangesiinae and Acanthotaeniinae

Scolex Morphology of Proteocephalid Cestodes Parasites of Neotropical Freshwater Fishes

The morphology of the scolices and metascolices of 29 proteocephalid species, parasites of freshwater fishes from Brazil was compared by using scanning electron microscope, light and laser microscopy. The following species were evaluated: Proteocephalus vazzolerae, P. piramutab, Robertiella paranaensis, Travassiella avitellina, Monticellia loyolai, M. spinulifera, M. belavistensis, Houssayela sudobim, Zygobothrium megacephalum, Gibsoniela mandube, Cangatiella arandasi, Nomimoscolex sudobim, N. lopesi, N. admonticellia, N. piraeeba, N. pirarara, Harriscolex kaparari, Crepidobothrium eirasi, Spatulifer rugosa, Megathylacus brooksi, Choanoscolex abscisus, Amphoteromorphus peniculus, A. piraeeba, Paramonticellia itaipuensis, Peltidocotyle rugosa, Othinoscolex lenha, Rudolphiella rugata, R. piranabu, Jauella glandicephalus. Some features as overall shape of scolex, suckers, apical sucker, frontal glands and several kinds of metascolex were analyzed. The taxonomic importance of scolex and metascolex is discussed
