O objetivo deste trabalho foi apresentar os aspectos reprodutivos de Harttia carvalhoi, Miranda Ribeiro, 1939, um pequeno loricariídeo cuja distribuição é restrita a área de drenagem do rio Paraíba do Sul. Um total de 110 exemplares de H. carvalhoi foi obtido. O período reprodutivo acontece desde setembro até fevereiro. O tipo de desova foi identificado como total e a taxa de fecundidade variou de 16 a 106 ovócitos. Este tipo de estudo é importante, visto que fecundidade é uma característica específica e é uma adaptação às condições do ciclo de vida, variando com o crescimento, densidade populacional, alimentos disponíveis e taxa de mortalidade. Também foi enfatizada a importância deste estudo, pois não há estudos prévios sobre a reprodução desta espécie

Amphibians exhibit great morphological plasticity of habitat and life history. This heterogeneity contributes to the frequency of occurrence and diversity of sexual dimorphism (shape or size) is large. Dasypops schirchi is a species belonging to the subfamily and family Gastrophryninae Microhylidae and this endemic and endangered. Generally, very little is known about D. schirchi, much in part to its habit of living and cryptic small geographical distribution. In order to detect and characterize elements sexually dimorphic in this species was a survey of specimens of D. schirchi in major national zoological collections. We analyzed 16 morphometric variables were also searched and secondary sexual characters non-morphometric. Statistical analysis of the morphometric data, the results showed a clear distinction between males and females of D. schirchi, secondary sexual characters nonmorphometric were also found

We can notice in Brazilian literature —both past and contemporary— the presence of the historical novel in its several modalities which include traditional models but also contemporary formulations that break old models with irreverence. Among them are the historiographical metafictions (Hutcheon, 1991), which propose the rereading not only of history but also of literature itself. Therefore, in the large number of historical characters which are fictionalized by contemporary Brazilian historical novel in the last decades, this essay intends to discuss how Ana Miranda engages in reading the history of Brazilian literature through fiction in three of her novels. The first is Boca do inferno (1989), whose protagonists are two of the main representatives of Brazilian colonial barroque, Father Antônio Vieira and poet Gregório de Matos. Following the chronological order of protagonist writers, the next novel to be discussed is Dias & dias (2002), whose action is centered in Gonçalves Dias, a well known poet of national Romanticism. The third is A última quimera (1995), which makes an outline of Brazilian literature at the beginning of the 20th century, dealing with Augusto dos Anjos and Olavo Bilac. By inverting some traditional viewpoints, Ana Miranda proposes, as in a palimpsest, the rereading and discussion of the national literary cânon and its construction.

Microlepidogaster bahiensis Miranda-Ribeiro (1918), assigned to Parotocinclus Eigenmann & Eigenmann, 1889, by Garavello (1977), was described in a short and uninformative way which does not allow for its distinction from other species of Parotocinclus; besides, the two syntypes of the species are regarded as lost. For these reasons a neotype is herein designated and a detailed description of the species is presented based on topotypes. The species is characterized by the combination of the following features: scapular bridge almost completely exposed ventrally, arrector fossae, when present, small or very reduced; abdomen covered by 5-7 wide lateral plates on each side and very small platelets in between, leaving abundant naked areas surrounding them; a small group of larger plates in front of anus; caudal peduncle ellipsoid in cross section; total plates in median series 21-23; longitudinal series with 23-26 plates; 18-29 teeth on premaxillary and 12-24 on dentary; it can also be distinguished by its characteristic caudal-fin color pattern. Features that allow us to assign the species to Parotocinclus and a hypothesis about its relationships with other species of the genus are also presented.

A new species of Proceratophrys is described from the highlands of northeastern Brazil. Molecular and morphological data suggests that Proceratophrys redacta sp. nov. is sister to P. minuta, and related to P. schirchi and P. cristiceps. The new species is diagnosed by its small size, absence of rostral and palpebral appendages, sagittal ridges interrupted, absence of postocular swellings, snout vertical in profile and dorsal coloration lacking distinct ocelli. The new species represents another example of endemism for the genus Proceratophrys in Chapada Diamantina region, and of another appendageless small-sized species associated with highlands. The phylogenetic results indicate that current morphological groupings in Proceratophrys may not represent natural groups.

A new species of Pseudopaludicola is described from the Cerrado of southeastern Brazil. The new taxon is diagnosed from the P. pusilla species group by the absence of either T-shaped terminal phalanges or toe tips expanded, and promptly distinguished from all (13) recognized taxa currently assigned to Pseudopaludicola by possessing isolated (instead of regular call series), long (117-187 ms) and non-pulsed advertisement calls.
