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

In the present work the authors propose a new species under the genus Lecithochirium Luehe, 1901, wich is enclosed in the third group of Freitas & Gomes distribuition (1971), nearest to L. manteri Freitas & Gomes, 1971, differing from it mainly by possessing open type sinus sac, externai ejaculatory vesicle lacking, seminal vesicle divided into 3 parts and bigger eggs. The authors present Pomatomus saltatrix (L.) as a new host record for Parahemiurus merus (Linton, 1910) Yamaguti, 1938, giving the variations they found in measurements. To Acanthocollaritrema umbilicatum Trav., Freitas & Buhrnheim, 1965 they add the presence of complex genital atrium and for this reason suggest that probably Acanthocollaritrematinae Trav., Freitas & Buhrnheim, 1965 must be put under Cryptogonimidae Ciurea, 1933. They also refer Bucephalopsis callicotyle Kohn, 1962, Microcotyle pomatomus Goto, 1899 (Polystomata) and some immature cestode under Trypanorhyncha Diesing, 1863 (Cestode), in Pomatomus saltatrix (L.).

Redescription of Oncophora melanocephala (Rudolphi, 1819) Baudin-Laurencin, 1971 (Nematoda, Camallanidae)

Oncophora melanocephala, a camallanid nematode from the small intestine of Priacanthus arenatus Cuvier, 1829 is redescribed from the Coast of Rio de Janeiro State, Brazil and this occurrence represents a new host record for the species

Contribuição ao conhecimento de Thubunaea dactyluris karve, 1938 (Nematoda, Spiruroidea)

In this paper the authors redescribe Thubunaea dactyluris Karve, 1938 in a new host; this is the first reference of this genus in Brazil. The nematodes were recovered from the stomach of Ameiva ameiva (L.), from Anil Beach, Rio de Janeiro State, Brazil. The authors studied eight males and ten females. Nine figures and one measurement table are presented, showing all these variations.

Novas considerações morfológicas e sistemáticas sobre os Procamallanus brasileiros (Nematoda, Camallanoidea)

After studying 63 Procamallanus samples recovered from Brazilian freshwater fishes, the authors in this third article on the subject propose two new species: Procamallanus Spinocamallanus) pexatus from Pygidium brasiliensis (Reinh.) and Procamallanus (Procamallanus) peraccuratus from Geophagus brasiliensis (Quoy & Gmard.) and Cichlasoma facetum (Jenyns) (Cichlaurus facetus) as well as consider Procamallanus (Spirocamallanus) probus Pinto & Fernandes, 1972, synonym of Procamallanus (Spirocamallanus) inopinatus Travassos, Artigas & Pereira, 1928, after rechecking the type amount of the former. They also affix an unidentified sample as Procamallanus (Spirocamallanus) sp.

Procamallanus brasileiros - parte I (Nematoda, Camallanoidea)

By introducing this work on brazilian nematodes under Procamallanus Baylis, 1923, the authors propose that Spirocamallanus Olsen, 1952, must be regarded only as a good subgenus based on the aspect of the buccal capsule. For this reason, Spirocamallanus should identify those worms bearing spiral thickenings, as well as similar structures inside their buccal cavity while Procamallanus may be applied every time the nematodes present a completely smooth capsule, lacking the above mentioned structures. Regarding to the early propositions in order to subdivide the genus using number and shape of the spicules as differential characters, the authors fully disagree with this point of view, which is rather a poor criterion, for the spicules are weakly chitinised in this group and for this reason they do not present enough strutural uniformity to be of great systematic significance. The authors deal here with three species: Procamallanus (Spirocamallanus) rarus Travassos, Artigas & Pereira, 1928, Procamallanus (Spirocamallanus) pimelodus and Procamallanus (Spirocamallanus) intermedius. The last two are proposed as new species. Procamallanus (S.) pimelodus is related to Procamallanus (Spirocamallanus) olseni Campanarouget & Razahihelissoa, 1965 and differs from it mainly by its caudal alae which shows a strongly muscular fringed rim. Procamallanus (S.) intermedius only comes nearer to Procamallanus (S.) rarus by possessing the bigger spicule with distal bifurcation and differs from it by the aspect of the buccal capsule which has more and thinner spiral thickenings. Of Procamallanus (S.) rarus, the female is described, a redescription of the male is presented and the very peculiar aspect of the bigger spicule is pointed out for the first time in the genus. This was also observed when dealing with Procamallanus (S.) intermedius, after examining the type of Procamallanus (S.) rarus. In this first part of the work the authors handled 31 samples of nematodes as follows: From intestines of Pimelodus clarias (L.)(27); Catfish (indeterminate)(3) and Pimelodella lateristriga (Mull. Trosch.)(1).

Sobre alguns Helmintos parasitos de Dryadophis Bifossatus (Raddi)

The authors study some helminths recovered from 5 samples of Dryadophis bifossatus (Raddi). For Oochoristica vanzolinii Rego e Rodrigues, 1965 nad Paradistomum parvissimum (Travassos, 1918) Travassos, 1919, they give a new host record. They only refer Infidum similis Travassos, 1916 as well as redescribe and add new drawings when dealing with Kalicephalus costatus costatus (Rudolphi, 1819) Schad, 1962.

Estudo de dois trematódeos parasitos de peixes marinhos

Rhipidocotyle angusticolle Chandler, 1941 is refered for the first time in Brazil in a new host, Scomber colias Gm., from Cabo Frio Coast, Rio de Janeiro State. Opecoeloides pedicathedrae Travassos, Freitas & Buhrnheim, 1966 is redescribed, also in a new host, Menticirrhus americanus (L.), from Maua Beach, Rio de Janeiro State. Morphological redescriptions and original figures of this species are presented.

Novas contribuicões ao conhecimento do gênero Procamallanus (Nematoda, Camallanoidea)

Carryng on the work related to the Brazilian Procamallanus, we rectify a few statements as well as confirm several ones appraising former species proposed and inserted in this paper and arise a new one. 1. procamallanus (S.) solani n. sp. was related to the nearest four brazilian species and their relationship is displaied on table I. 2 Procamallanus (S.)inheringi Travassos, Artigas & Pereira, 1928. The aspect of buccal capsule in males and females of our material was absolutely not that one described by Travassos & cols., since they were mistaken in their description, inverting the number of spiral thickenings in the buccal capsule of the latter. In order to compare our material with that assigned as type, we present camera lucida drawings and photomicrographies of both samples. 3. Procamallanus (S.) inopinatus Travassos, Artigas & Pereira, 1928. Its description and drawings were abridged and adapted from Pinto & Noronha, 1972. 4. Procamallanus (S.) amarali Vaz & Pereira, 1934. We found among fully males of the species, only tiny and diaphanous immature female nematodes in which we could observe the genitalia and buccal capsule in several developing phases. A sole young female speciment, owing a very short, smooth and thin walled ovejector was the basis for the description we present.

Revisão da subfamília Atactorhynchinae Petrotschenko, 1956 (Acanthocephala - Neoechinorhynchidae)

In this paper, the authors revise the sub-family Atactorhynchinae Petrotschenko, 1956, after studying types of Floridosentis mugilis (Machado Filho, 1951) and material recovered from intestine of Mugil sp. from Cabo Frio, Estado do Rio de Janeiro, Brasil. They confirm what was suggested by Bullock, 1962, about a new combination for the type species of Floridosentis Ward, 1953. For this reason, they make F. elongatus, synonym of F. mugilis Machado Filho, 1951. Besides they also enlarge the subfamily diagnosis and add a table showing the maind differences between the two genera under Atactorhynchinae Petrotschenko, 1956.
