Thaptomys Thomas 1915 (Rodentia, Sigmodontinae, Akodontini) with karyotypes 2n = 50, FN = 48, and 2n = 52, FN = 52: two monophyletic lineages recovered by molecular phylogeny

A novel karyotype with 2n = 50, FN = 48, was described for specimens of Thaptomys collected at Una, State of Bahia, Brazil, which are morphologically indistinguishable from Thaptomys nigrita, 2n = 52, FN = 52, found in other localities. It was hence proposed that the 2n = 50 karyotype could belong to a distinct species, cryptic of Thaptomys nigrita, once chromosomal rearrangements observed, along with the geographic distance, might represent a reproductive barrier between both forms. Phylogenetic analyses using maximum parsimony and maximum likelihood based on partial cytochrome b sequences with 1077 bp were performed, attempting to establish the relationships among the individuals with distinct karyotypes along the geographic distribution of the genus; the sample comprised 18 karyotyped specimens of Thaptomys, encompassing 15 haplotypes, from eight different localities of the Atlantic Rainforest. The intra-generic relationships corroborated the distinct diploid numbers, once both phylogenetic reconstructions recovered two monophyletic lineages, a northeastern clade grouping the 2n = 50 and a southeastern clade with three subclades, grouping the 2n = 52 karyotype. The sequence divergence observed between their individuals ranged from 1.9% to 3.5%.

The subfamily Aephnidiogeninae Yamaguti, 1934 (Digenea: Lepocreadiidae), its status and that of the genera Aephnidiogenes Nicoll, 1915, Holorchis Stossich, 1901, Austroholorchis n g, Pseudaephnidiogenes Yamaguti, 1971, Pseudoholorchis Yamaguti, 1958 and N

The status of all of the putative member genera of the subfamily Aephnidiogeninae is reconsidered, based mainly on the morphology of the terminal genitalia, Aephnidiogenes Nicoll, 1915 is the only genus retained in the Aaephnidiogeninae. Aephnidiogenes major Yamaguti, 1934 from Diagramma labiosum from the southern Great Barrier Reef is redescribed with particular reference to the terminal genitalia, and is shown to lack a true cirrussac, a condition considered to be diagnostic of the Aephnidiogeninae. Holorchis Stossich, 1901 is placed in the subfamily Lepidapedinae. Holorchis pycnoporus Stossich, 1901 from Pagellus acarne from off Spanish Sahara and from Diplodus vulgaris from off Italy and H. legendrei Dollfus, 1946 from Sparodon durbanensis and D. sargus from off eastern Cape Province, South Africa and from Pagellus erythrinus from the Adriatic Sea and Italy are studied and illustrated. The terminal genitalia of H. pycnoporus are found to be enigmatic, but those of H. legendrei are found to fit clearly into the 'Lepidapedon-like' pattern. A new genus Austroholorchis is erected in the Lepidapedinae, with A. sprenti (Gibson, 1987) n. comb. as the type-species. Its diagnostic features are its ani, infundibuliform oral sucker and the position of the ovary at about mid-level of the uterus. A. sprenti is illustrated, its hosts in Queensland waters being Sillago maculata, S, analis and S. ciliata. A, levis n. sp. is described from Sillago bassensis from south-western Western Australia. The genus Pseudaephnidiogenes Yamaguti, 1971 is placed in the Lepidapedinae. P. rhabdosargi (Prudhoe, 1956) from Rhabdosargus sarba from off Natal, South Africa is illustrated and the terminal genitalia of P. rhabdosargi from R. sarba and from R. holubi from off eastern Cape Province and Pseudaephnidiogenes vossi Bray, 1985 from Caffrogobius nudiceps from off eastern Cape Province, South Africa are illustrated. The genus Pseudoholorchis Yamaguti, 1958 is placed in the subfamily Lepocreadiinae. The terminal genitalia of P. pulcher (Manter, 1954) from Latridopsis ciliaris from New Zealand are illustrated, The genus Neolepocreadium Thomas, 1960 is placed in the Lepocreadiidae.

Observações sobre a ocorrência de Mosca-Negra-dos-Citros, Aleurocanthus woglumi Ashby, 1915 (Hemiptera: Sternorrhyncha: Aleyrodidae) no estado do Amazonas

A mosca-negra-dos-citros (Aleurocanthus woglumi Ashby) é uma importante praga dos citros de origem asiática. Foi detectada no Brasil pela primeira vez em Belém-PA em 2001. Este trabalho tem como objetivo registrar a ocorrência de mosca-negra-dos-citros no estado do Amazonas, sua distribuição geográfica e estudos de biologia em condições de laboratório. A mosca-negra encontra-se atualmente disseminada em mais da metade dos municípios paraenses. No Amazonas foi detectada em junho de 2004 em Manaus e atualmente encontra-se disseminada em toda a área urbana deste município, ocorrendo também em Itacoatiara, Rio Preto da Eva e Iranduba. Em observações feitas em condições de laboratório em Manaus-AM, foi verificado que o ciclo de ovo-adulto foi de 71,76±2,07 dias, caracterizando como uma espécie multivoltina.

Contribuição ao conhecimento da tribu Ormiini. III: gênero Euphasiopteryx Townsend, 1915 (Diptera, Tachinidae)

This is a contribution to the knowledge of the Tribu Ormiini in wich the author presents redescriptions of euphasiopteryx depleta (Wiedemann, 1830), Euphasiopteryx ochracea (Bigot, 1888) and describes a new species: Euphasiopteryx rosenoi sp. n. from Brazil.

Contribuição ao conhecimento da tribu Ormiini: IV: gêneros Ormia Robineau Desvoidy, 1830, e, Euphasiopteryx Townsend, 1915 (Diptera, Tachinidae)

Studying thirteen speciemens of the genus Ormia Robineau-Desvoidy, 1830, and one of Euphasiopteryx Towsend, 1915, the author describes six new species: Ormia mendesi sp. n., Ormia lenkoi sp. n., Ormia carreirai sp. n., Ormia crespoi sp. n., Ormia wygodzinskyi sp. n., and Euphasiopteryx lenti sp. n. from Brasil and Argentina. The importance of the ocelli as a generic character, as stated by Towsend (1936) is discussed based on the absence of ocelli in Ormia mendesi sp. n. and Ormia crespoi sp. n. and its presence in Euphasiopteryx lenti sp. n. A key for the determination of Ormia species is presented based chiefly on the males external morphological characters.

A critical edition of Joseph Conrad's "Because of the dollars" (Within the Tides, 1915)

Cette thèse de doctorat, écrite en anglais, propose la première édition critique de « Because of the Dollars », une nouvelle de l'écrivain anglais Joseph Conrad publiée dans le volume Within the Tides, en février 1915. Outre le texte critique de la nouvelle - le seul à ce jour reconstruit d'après une minutieuse étude des relations entre toutes les versions existantes - la présente édition offre aussi un vaste apparat éditorial. Le texte de la présente édition est éclectique. Sa ponctuation est essentiellement basée sur un texte proche du manuscrit de l'auteur, et donc non corrompu par le processus de transmission. Mais ses mots sont tirés des dernières versions révisées par l'auteur, étant donné qu'au cours de la transmission, les mots, contrairement aux marques de ponctuation, n'ont pas été contaminés. Le résultat de cette méthode est un texte reflétant, tant pour les mots que pour la ponctuation, les choix de l'auteur. L'apparat éditorial sert à placer la nouvelle dans la vie de Conrad, tracer l'évolution du texte, et offrir au lecteur des informations historiques et culturelles qui permettront une meilleure lecture de l'oeuvre. Cet apparat est composé de quatre parties : une introduction, une étude sur les textes de la nouvelle, une collation historique de toutes les variantes, et des notes explicatives. L'introduction place l'oeuvre dans le contexte de la vie de l'écrivain, en donne la réception critique de 1915 à nos jours, et en éclaire le contexte historique (un changement de monnaie à Singapour en 1903-4). L'étude sur les textes trace le développement et la transmission du texte, depuis son inscription sur pages manuscrites jusqu'à sa publication dans les oeuvres complètes de Conrad. La collation historique inventorie toutes les variantes textuelles entre les différentes versions existantes. Enfin, les notes explicatives glosent les allusions littéraires, historiques, et culturelles du texte. « Because of the Dollars » et Within the Tides n'ayant attiré que très peu d'attention critique, les informations contenues dans cet apparat éditorial sont complètement inédites, et jettent une lumière originale sur une période peu étudiée de la vie de Conrad.
