Taxonomy of ""Mouse-colored Tapaculos"". I. On the application of the name Malacorhynchus speluncae Menetries, 1835 (Aves: Passeriformes: Rhinocryptidae)

The type specimen of Malacorhynchus speluncae was described and illustrated as being ""mouse gray with a bluish luster"" on the upperparts and as having a ""lighter color on the lower side of the body"" which ""becomes whitish towards the middle of the throat and breast"". It represents a taxon presently placed in the genus Scytalopus. Since 1907, the name Scytalopus speluncae has been attributed to the predominantly dark-gray species from the southeastern coastal Brazilian mountains. Recently, it was suggested that the name S. speluncae should be applied to a species that is light-gray with whitish belly and extensive barring on the flanks and that occurs predominantly in the Espinhaco Range, Minas Gerais state, to the west of the range of the dark-gray taxon. As a consequence, the dark-gray species, presumably without any available name, was described as a new species, S. notorius. However, on the basis of a critical analysis of the available information on the type specimen of S. speluncae, including the original description and illustration (Menetries 1835), and our examination of large series of museum specimens, we demonstrate that the type of S. speluncae falls within the known plumage variation of the dark-gray species and that it does not show the diagnostic characters of the light-gray form. Thus, we propose that the name S. speluncae be applied only to the dark-gray species. Consequently, S. notorius must be regarded a junior-synonym of S. speluncae. Because of problems related to the exact collecting sites of Menetries, and taking into consideration the distribution of the dark-gray species, we suggest ""Serra dos Orgaos"", in Rio de Janeiro state, as the type-locality of S. speluncae.

Podochela meloi Sankarankutty, Ferreira & Cunha, 2001, a junior synonym of the spider crab Inachoides forceps A. Milne-Edwards, 1879 (Crustacea: Brachyura: Inachoididae)

Podochela meloi Sankarankutty, Ferreira & Cunha, 2001, originally described in the Inachidae MacLeay, 1838, was recently transferred to the Inachoididae genus Inachoides H. Milne Edwards & Lucas, 1842, based upon overall similarities. Placement of P. meloi in both Inachoididae and Inachoides is found to be supported by a number of synapomorphies as shown herein. Podochela meloi is shown to be a junior synonym of Inachoides forceps A. Milne-Edwards, 1879.

Two new genera, ten new species and new records of Amazonian Stygnidae Simon, 1879 (Opiliones: Laniatores)

As a result of recent expeditions to two mountains in the Amazon basin, Tapirapeco and Pico da Neblina, two new genera of Stygnidae, Imeri g. nov. (type species Imeri lomanhungae sp. nov.) and Jime g. nov. (type species Jime chifrudo sp. nov.), and ten new species are described: Auranus hehu sp. nov., Auranus tepui sp. nov., Imeri lomanhungae sp. nov.; Jime chifrudo sp. nov.; Stygnoplus ianomami sp. nov.; Stygnus magalhaesi sp. nov.; Stygnoplus neblina sp. nov.; Stygnoplus tapirapeco sp. nov.; Stygnus nogueirai sp. nov., Stygnus kuryi sp. nov.. Additionally, new distributional records in Amazonas (Brazil) are presented for Stygnidius guerinii Soerensen, 1932, Minax tetraspinosus Pinto-da-Rocha, 1997 and Protimesius longipalpis (Roewer, 1943). Keys for genera of Heterostygninae and Stygninae are provided.

Brazilian sardine (Sardinella brasiliensis Steindachner, 1879) spawning and nursery habitats: spatial-scale partitioning and multiscale relationships with thermohaline descriptors

We provide a detailed account of the spatial structure of the Brazilian sardine (Sardinella brasiliensis) spawning and nursery habitats, using ichthyoplankton data from nine surveys (1976-1993) covering the Southeastern Brazilian Bight (SBB). The spatial variability of sardine eggs and larvae was partitioned into predefined spatial-scale classes (broad scale, 200-500 km; medium scale, 50-100 km; and local scale, <50 km). The relationship between density distributions at both developmental stages and environmental descriptors (temperature and salinity) was also explored within these spatial scales. Spatial distributions of sardine eggs were mostly structured on medium and local scales, while larvae were characterized by broad-and medium-scale distributions. Broad-and medium-scale surface temperatures were positively correlated with sardine densities, for both developmental stages. Correlations with salinity were predominantly negative and concentrated on a medium scale. Broad-scale structuring might be explained by mesoscale processes, such as pulsing upwelling events and Brazil Current meandering at the northern portion of the SBB, while medium-scale relationships may be associated with local estuarine outflows. The results indicate that processes favouring vertical stability might regulate the spatial extensions of suitable spawning and nursery habitats for the Brazilian sardine.

On some species of Taeniotes Audinet-Serville, 1835 (Coleoptera: Cerambycidae: Lamiinae)

Taeniotes farinosus (Linnaeus, 1758) is a species that has been confused with other species during the past two centuries. In this work we demonstrate that Taeniotes farinosus sensu auctorum is not the species described by Linnaeus and designate a lectotype to establish its identity. Taeniotes pulverulentus (Olivier, 1790), currently synonymous with T. farinosus, is revalidated. Taeniotes guttullaris Schwarzer, 1929 and T parafarinosus Breuning, 1971 are junior synonyms of T. pulverulentus; Lamia subocellata Olivier, 1792 (= Taeniotes subocellatus) is a junior synonym of Cerambyx farinosus (= T farinosus). Additionally we monnei, a new species from Brazil and Argentina, is described and figured. Taeniotes peruanus provide annotated bibliographic references to T. farinosus and T pulverulentus. Taeniotes Breuning 1971 is figured for the first time.

Quatro Desenhos de Frank Lloyd Wright

O objetivo deste trabalho é discutir aspectos do processo de projeto e sua representação gráfica, num momento em que softwares de projeto 3D vem se tornando hegemônicos na prática do arquiteto e no ensino de arquitetura, em contraponto às práticas de desenho em prancheta. Os motivos e circunstâncias não são objeto do trabalho, cujo foco está numa prática de projeto e representação gráfica 2D, mas que tem muito a contribuir para o debate do quadro acima: os desenhos de projeto de Frank Lloyd Wright. Casos de estudo: quatro pranchas desenhadas por FLLW. É importante notar que, no vasto quadro da historiografia wrightiana, análises e interpretações originais, pioneiras, da arquitetura vem surgindo nas últimas décadas, mas ainda há poucos textos sobre desenhos e representação gráfica do arquiteto. Este constitui uma primeira aproximação do autor acerca de tema que oferece abrangente potencial. São exemplos em que, na relação imagem-objeto, a representação bidimensional constrói o projeto tridimensional. A arquitetura emerge como experimentação sem cair na especulação formal. Demonstram uma prática mais lenta, reflexiva e laboriosa do que a oferecida pelos software 3D atuais – mas onde cada traço, textura e grafismo implica um significado de espaço e materialidade.

Os proprietários de escravos e a estrutura da posse na antiga freguesia de São Simão, 1835

Este artigo estuda a estrutura da posse de escravos em São Simão, localidade do nordeste paulista, utilizando a lista nominativa de 1835. O objetivo principal é analisar a estrutura da posse de escravos na região pouco antes da chegada do café, pois, ao que tudo indica, a estrutura produtiva formada nesse período teria contribuído para o rápido desenvolvimento da cultura cafeeira durante a segunda metade do século XIX. Destaca-se o caso de Ribeirão Preto, localidade desmembrada de São Simão nos primeiros anos da década de 1870, que chegou a ser a maior produtora de café do Estado de São Paulo.
