Contribuição para o conhecimento dos parasitos de peixes do litoral do Estado da Guanabara - parte II

Abstract

No presente trabalho os autores criam uma nova espécie para o gênero Lecithochirium Luehe, 1901, ficando no 3º grupo de distribuição de Freitas & Gomes (1971), mais se aproximando de L. manteri Freitas & Gomes, 1971, distinguindo-se principalmente por possuir saco genital aberto, vesícula ejaculadora externa ausente, vesícula seminal trilobada e ovos maiores. Apresentam Promatomus saltatrix (L.) como novohospedador para Parahemiurus merus (Linton, 1910) Yamaguti, 1938 ressaltando as variações encontradas nas medidas. Para Acanthocollaritrema umbilicatum Trav., Freitas e Bührnheim, 1965, acusam a presença do gonotil, e por esta razão acham que provavelmente Acanthocollaritrematinae Trav., Freitas e bührnheim, 1965, deva pertencer à família Cryptogonimidae Ciurea, 1933. Referem ainda a presença de Bucephalopsis callicotyle Kohn, 1962, Microcotyle pomatomi Goto, 1899 (polistomata) e larvas de Trypanorhyncha Diesing, 1863 (Cestoda0, em Pomatomus saltatrix (L.).

Pseudopecoelus sosoae sp. nov. and P. sewelli (Digenea, Opecoelidae) from the deep-sea fish Neoscombrops pacificus (Perciformes, Acropomatidae) off New Caledonia

“…Corrêa Gomes et al (1974) illustrated a worm identified as P. priacanthi from Epinephelus sp. (as Garrupa sp.)…”

Acanthocollaritrema umbilicatum Travassos, Freitas & Bührnheim, 1965 (Digenea: Acanthocollaritrematidae) from the Common Snook, Centropomus undecimalis, from Itamaracá, State of Pernambuco, Brazil

“…In the material studied herein, the presence of these features could not be clearly defined using a stereomicroscope with incident light and their existence were only confirmed with the SEM. Additionaly, these structures could not be observed in the specimens deposited by Travassos et al (1965) and Gomes et al (1972) under optical microscope.…”

“…According to Gomes et al (1972), the use of a different stain (cotton blue) allows observation of a genital atrium complex in the acetabular region. They also state that this complex, with a sac-like form, had an opening formed by a muscular ring, similar to a third sucker, characterizing a gonotyl.…”

“…This species has been reported only from Centropomus undecimalis collected along the coast of the states of Espírito Santo and Rio de Janeiro, Brazil (Travassos et al 1965, Gomes et al 1972, Wallet & Kohn 1987. Its systematic position was questioned by Gomes et al (1972), who reported a gonotyl associated to the acetabulum.…”
