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.

Introduction. Posttransplant thrombotic microangiopathy (TMA)/hemolytic uremic syndrome (HUS) can occur as a recurrent or de novo disease. Methods. A retrospective single-center observational study was applied in order to examine the incidence and outcomes of de novo TMA/HUS among transplantations performed between 2000 and 2010. Recurrent HUS or antibody-mediated rejections were excluded. Results. Seventeen (1.1%) among 1549 kidney transplant recipients fulfilled criteria for de novo TMA. The mean follow-up was 572 days (range, 69-1769). Maintenance immunosuppression was prednisone, tacrolimus (TAC), and mycophenolic acid in 14 (82%) patients. Mean age at onset was 40 +/- 15 years, and serum creatinine was 6.1 +/- 4.1 mg/dL. TMA occurred at a median of 25 days (range, 1-1755) after transplantation. Nine (53%) patients developed TMA within 1 month of transplantation and only 12% after 1 year. Clinical features were anemia (hemoglobin < 10 g/dL) in 9 (53%) patients, thrombocytopenia in 7 (41%), and increased lactate dehydrogenase in 12 (70%). Decreased haptoglobin was observed in 64% and schistocytes in 35%. Calcineurin inhibitor (CM) withdrawal or reduction was the first step in the management of 10/15 (66%) patients, and 6 (35%) received fresh frozen plasma (FFP) and/or plasmapheresis. TAC was successfully reintroduced in six patients after a median of 17 days. Eight (47%) patients needed dialytic support after TMA diagnosis and 75% remained on dialysis. At 4 years of follow-up, death-censored graft survival was worse for TMA group (43.0% versus 85.6%, log-rank = 0.001; hazard ratio = 3.74) and there was no difference in patient survival (53.1% versus 82.2%, log-rank = 0.24). Conclusion. De novo TMA after kidney transplantation is a rare but severe condition with poor graft outcomes. This syndrome may not be fully manifested, and clinical suspicion is essential for early diagnosis and treatment, based mainly in CM withdrawal and FFP infusions and/or plasmapheresis.

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.

Joseph Barbosa de Sáa (? – 1775), mais conhecido por seus escritos sobre a história do estado do Mato Grosso, Brasil, completou em 1769 um volumoso (408 fólios) e erudito manuscrito, intitulado “Dialogos geograficos, coronologicos, polliticos e naturais”, que nunca foi publicado na íntegra. Esse manuscrito está depositado na Biblioteca Pública do Porto (manuscrito no. 235), em Portugal. Dez capítulos desse manuscrito tratam dos produtos naturais do Brasil (acima de mil, quase a metade sendo animais), observados por Sáa ao longo da costa do Rio de Janeiro, em São Paulo, sul de Goiás e especialmente no Mato Grosso, sendo a primeira monografia sobre a história natural deste último estado. Esses capítulos são aqui transcritos e comentados.

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.
