Sobre Dipetalonema spiralis (Molin, 1860) (Nematoda, Filarioidea)

The authors give a description of Dipetalonema spiralis (Molin, 1860), based on two samples collected by the C. E. E. L. V. A. in the joints of the hands and feet of Choloepus didactylus (L.) at Piratuba, State of Pará, Brazil, both containing males and females. A study of the literature is made and original drawings are presented.

Filariopsis barretoi (Travassos, 1921) comb. n. parasito de "Mico-estrela", ocorrência e patogenia (Nematoda, Metastrongylidae)

O autor reestuda a espécie Filariopsis barretoi (Travassos, 1921) parasita de pulmões de Callithrix jacchus (mico-estrela). Trata-se da segunda observação destes parasitas. É feito um resumo histórico destes metastrongilídeos de pulmão de macacos. O autor complementa ainda a descrição original de Travassos e faz observações sobre a patogenia determinada pelos vermes no pulmão do macaco. É proposta uma nova combinação: a espécie é transferida do gênero Filaroides Van Beneden, 1858 para o gênero Filariopsis Van Thiel, 1926, em vista de apresentar três lábios na face oral; estes vermes passam a chamar-se Filariopsis barretoi (Travassos, 1921) Rego, 1974.

Del despoblament a la revitalització demogràfica: els canvis en el comportament de la població al Pirineu català (1860-2006) : el cas de l’Urgellet i el Baridà (Alt Urgell-Cerdanya)

El treball es centra en l’estudi de l’evolució demogràfica de dues subcomarques del Pirineu català, l’Urgellet i el Baridà, entre mitjans del segle XIX i la darrera explotació estadística del padró d’habitants (2006). En la primera part del treball s’aporten bases teòriques sobre el procés de despoblament que han experimentat les àrees de muntanya catalanes i sobre el lent procés de recuperació que part d’aquests territoris experimenten en l’actualitat. A continuació es realitza un anàlisi estadístic en profunditat de les diferents etapes del despoblament, del canvi de tendència que es produeix a partir de la dècada de 1980 i de la recent revitalització demogràfica. Per últim, es presenten alguns dels factors explicatius d’aquest procés de recuperació demogràfica que afecta a determinats indrets del Pirineu català.

What is Anopheles Allopha (Lutz & Peryassú, 1921) (Diptera: Culicidae)?

We regard Anopheles (Nyssorhynchus) allpha (Lutz & Peryassú, 1921) as a nomen nudum in view of the ambiguities in its original description, as explained in this note.

Filariopsis barretoi (travassos, 1921) (Nematoda: metastrongyloidea) lung parasite of primates from South America - taxonomy, synonyms and pathology

Nematodes and fragments of lungs from Cebus ssp., Callithrix jacchus (l.) and Saimiri sciureus (L.) were studied. The worms from Cebus and Callithrix must be called Filariopsis barretoi (Travassos, 1921). The names Filariopsis arator Chandler, 1931 and Filaroides cebi Gebauer, 1933 are synonymized to F. barretoi. The status of Filariopsis gordius (Travassos, 1921) remains uncertain. The pathology is described. The parasites are located in the pulmonary paranchyma, near the pleural surface, constituting nodules.

New host records and localities of some Monogenea from brazilian marine fishes with scanning electron microscopy of Bicotylophora trachinoti (Mac Callum, 1921)

Bicotylophora trachinoti (Mac Callum, 1921) from Trachinotus carolinus L.; Pseudanthocotyloides heterocotyle (Van Beneden, 1871) from Cetengraulis edentulus (Cuvier), and Decapterus punctatus (Cuvier), new host records; Pseudomazocraes selene Hargis, 1957 from Selene vomer (L.) and Caranx latus Agassiz, new host record, are reported for the first time in Brazil from the coast of Rio de Janeiro State. The marine fishes Diplectrum sp. and Pomatomus saltatrix (L.) are respectively new host records for Pseudotagia cupida (Hargis, 1956) and Macrovalvitrema sinaloense Caballero & Bravo Hollis, 1955. Measurements, original figures and photos in scanning electron microscopy of B. trachinoti are presented. The egg with filaments is reffered for the first time in the genus Pseudanthocotyloides.

On Thelazia anolabiata (Molin, 1860) Railliet & Henry, 1910 (Nematoda, Thelazioidea): a new host record and systematic considerations

Thelazia anolabiata (Molin, 1860) Raillet & Henry, 1910, parasite of eyes of birds, is reported in s new host, Ortalis canicolis pantanalensis Cher & Reich from Salobra, Mato Grosso do Sul State; T. digitata Travassos, 1918 and T. lutzi Travassos, 1918 are considered its synonyms.
