A new Brazilian species of Loxandrus LeConte, 1852, with description of immatures and notes on natural history (Coleoptera: Carabidae: Loxandrini)

Loxandrus oophagus sp. nov. is described (type-locality: Uberlandia, State of Minas Gerais, Brazil). Larvae, pupae and adults of the new species of the carabid beetle were collected on foam nests of the anuran Leptodactylus fuscus (Schneider, 1799) in the surroundings of Uberlandia, 18 degrees 55S, 48 degrees 17W (Brazil, Minas Gerais), at 750 m altitude. The new species is compared with the similar Loxandrus quinarius Will & Liebherr, 1997, only known from Santa Cruz, Bolivia, differing by the morphology of tarsomeres. Larvae prey on anuran eggs. Description of the immatures and the natural history of the species are provided. The larva differs from the known larvae of Loxandrus species mainly by being eruciform, glabrous and depigmented, its small head and legs, and the lack of stemmata and urogomphi, representing an unusual last instar type among the Carabidae.

Descriptions of Macrolygistopterus subparallelus Pic, 1930 immatures from southeastern Brazil (Coleoptera, Lycidae, Lycinae, Calochromini)

Mature larva and pupa of Macrolygistopterus subparallelus Pic are described and compared to known Calochromini immatures. Larvae were collected alive inside dead trunk in the Atlantic Forest at Estacao Biologica de Boraceia, Salesopolis, Sao Paulo, Brazil. They were maintained in laboratory conditions, and the pupal period was 12 days (one observation). The pupa of this genus is described for the first time. This larva differs from known Calochromini larvae mainly because of its almost cylindrical campodeiform body and longer urogomphi.

Redescription of the enigmatic Thoracotropis cypriformis Freeman (Diptera, Mycetophilidae)

Redescription of the enigmatic Thoracotropis cypriformis Freeman (Diptera, Mycetophilidae). The Chilean species Thoracotropis cypriformis, type species of the monotypic genus Thoracotropis, is redescribed based on the only known specimen, the holotype. Habitus, head, wing venation, and male terminalia are illustrated. Comments are made on the diagnostic features of the genus and on its position in the subfamily to which it is usually assigned, the Leiinae.

TITANS OF CAPITALISM IN THE MODERNIZATION OF BRAZILIAN TERRITORY: URBAN AND AWARDS PUBLIC ASSISTANCE DURING THE FIRST REPUBLIC (1889-1930)

In Brazil, the newly created Republic expressed interests of the elite increasingly committed to foreign capital. The Rio de Janeiro saw accumulate vast resources in trade and finance, deriving for industrial applications. The city appears as articulator of Brazilian territory and mediation between it and the international market. In the capital of the Republic, the conservative plan would sweep the old city and inaugurate images copied from Europe and installed in the tropics with civilizing purpose. This materialized with infrastructure financing and loans to entrepreneurs in Europe and North America, awarded public service concessions. The project relied on strong support of mayors (members or representatives of the companies involved in the reforms). This work aims to address the relationship between the mayors of Rio de Janeiro during the First Republic and international capital, focusing on strategies for the production of new spaces in motion the modernization of Brazil and its international image.

A novel spermatozoan ultrastructure in the shrimp Hippolyte obliquimanus Dana, 1852 (Decapoda: Caridea: Hippolytidae)

The aim of this study was to describe and illustrate the morphology of the spermatozoon of the Western Atlantic shrimp, Hippolyte obliquimanus. Individuals were sampled from Itagua Beach (Ubatuba, southern Brazil). The male reproductive system was dissected and morphological analysis was undertaken using a stereomicroscope, a light microscope, and transmission electron and scanning electron microscopes. When viewed from the nuclear or acrosomal poles, each spermatozoon has many translucent radiating arms (about 20) from a denser cell body, while laterally the cell body and arms resemble a "cnidarian medusa", with all the arms projecting away from the bell-like cell body. This sperm morphology is distinct from the "thumbtack"-shaped spermatozoa observed in the majority of carideans but has similarities to the spermatozoa of Rhynchocinetes spp. The morphology of sperm of several species of the genus Hippolyte resembles the spermatozoon of H. obliquimanus with the presence of posterior nuclear arms, but it is necessary to study other Hippolyte species to place these arms in the context of the genus.

'Beheading', Rule Manipulation and Fraud: The Approval of Election Results in Brazil, 1894-1930

Studies of electoral fraud tend to focus their analyses only on the pre-electoral or electoral phases. By examining the Brazilian First Republic (1889-1930), this article shifts the focus to a later phase, discussing a particular type of electoral fraud that has been little explored by the literature, namely, that perpetrated by the legislatures themselves during the process of giving final approval to election results. The Brazilian case is interesting because of a practice known as degola ('beheading') whereby electoral results were altered when Congress decided on which deputies to certify as duly elected. This has come to be seen as a widespread and standard practice in this period. However, this article shows that this final phase of rubber-stamping or overturning election results was important not because of the number of degolas, which was actually much lower than the literature would have us believe, but chiefly because of their strategic use during moments of political uncertainty. It argues that the congressional certification of electoral results was deployed as a key tool in ensuring the political stability of the Republican regime in the absence of an electoral court.

BIOLOGICAL ASPECTS OF THE SAILFIN DORY Zenopsis conchifer (LOWE, 1852) CAUGHT BY DEEP-SEA TRAWLING FISHERY OFF SOUTHERN BRAZIL

Biological aspects of sailfin dory, Zenopsis conchifer, were studied from 839 individuals obtained from deep-sea commercial bottom trawling off southern Brazil at depths up to 526 m in 2002 and 2003. Samples included fish from 101 mm Lt and 15 g up to 640 mm Lt and 2,9 g. The sex-ratio was 50% at 150 mm Lt and between 300-350 mm Lt, with females outnumbering males in the remaining size classes. Reproductive activity seems to peak between July and August ( austral winter). Size at attainment of 50% maturity (Lt(50)) was 311 mm Lt in females. The mean length and maturity of the specimens increased with depth, suggesting that larger fish concentrate in deeper waters.

Morphological and genetic variability in Hippolyte obliquimanus dana, 1852 (Decapoda, Caridea, Hippolytidae) from Brazil and the caribbean sea

Hippolyte obliquimanus is a marine shrimp reported from the Caribbean Sea and Brazil. The literature provides indications for morphological variation between populations from those regions and the species has a troubled taxonomic history. The aims of this study were to analyse morphological and genetic variation in the populations of H. obliquimanus from Brazil and the Caribbean Sea and to verify if those might support separation of H. obliquimanus into two or more species. This hypothesis was tested with the analysis of morphological and genetic data (mitochondrial gene 16S and the barcode region Cytochrome Oxidase I). The material analysed was obtained from samples and from loans of zoological collections. The rostrum as well as pereiopods 3, 4, and 5 were the adult morphological characters that showed variation, but this occurred in samples from both regions, Brazil and the Caribbean Sea. The sequences of the 16S gene were identical among all specimens analysed. There was, however, variation among the sequences of the barcoding gene COI (<2.0%); this divergence separated the specimens into two groups (Brazil versus the Caribbean) and these groups did not share haplotypes. In conclusion, specimens from the regions analysed showed both morphological and genetic variation, but these did not support the separation of H. obliquimanus into two or more species.

Repercussões satíricas dos processos de escolarização do social nas ondas do rádio (1930-1940)

Este artigo analisa repercussões satíricas dos processos de escolarização do social no Brasil, presentes em antigos programas humorísticos de rádio, que, geralmente organizados pelo diálogo entre um professor e seus alunos, foram simultaneamente grandes sucessos em termos de audiência e alvos de uma crítica sistemática por parte daqueles que defendiam a radiodifusão como instrumento de divulgação da "verdadeira" cultura. Por meio do uso de fontes sonoras e impressas, objetiva compreender as razões do sucesso do gênero e, neste percurso, identificar as críticas à escola, à educação e seus sujeitos, que, jocosamente, veicularam, explicitadas em conflitos entre sonoras tradições populares e saberes escolares.

Entre antropologia e medicina: uma análise dos estudos antropológicos de Álvaro Fróes da Fonseca nas décadas de 1920 e 1930

O médico e antropólogo Álvaro Fróes da Fonseca percorreu várias cidades do Brasil durante sua trajetória profissional, na primeira metade do século XX. Atuou no magistério na cadeira de Anatomia Médico-Cirúrgica, nas Faculdades de Medicina de Porto Alegre, da Bahia e do Rio de Janeiro. Como antropólogo, exerceu atividades no Museu Nacional do Rio de Janeiro e, já nos anos 1960, no Instituto de Antropologia Tropical da Faculdade de Medicina do Recife. Pretendo, neste artigo, resgatar a contribuição do estudioso no campo antropológico, analisando algumas de suas pesquisas desenvolvidas no Laboratório de Antropologia do Museu Nacional e outras publicadas no periódico dessa instituição entre os anos 1920 e 1930. Neste período, ele congregou cientistas, desenvolveu e orientou vários trabalhos no âmbito da antropologia física e dos 'tipos antropológicos', voltando-se para o desenvolvimento de métodos e índices de classificação racial, ou seja, para a produção de conceitos e técnicas que orientavam a prática antropológica. Refutou o racismo científico do período, motivo pelo qual as investigações desenvolvidas por Fróes da Fonseca refletiram sobre o 'problema da raça' e a questão da mestiçagem em prol do futuro do Brasil.
