(2009). Therefore, considering the morphological and morphometric aspects, in addition to the geographical distribution of the genus, we consider our allocation of the new species to <i>Aparasphenodon</i> as merely tentative.</p> <p>The species is characterized by: (1) medium size (males SVL 51.6–60.5 mm, n = 4; females SVL 58.7–62.1 mm, n = 4; Table 1); (2) head longer than broad; (3) iris red; (4) snout almost rounded in dorsal view and acute in profile; (5) dorsum and limbs with cream-colored reticulation on dark-brown background; (6) lips white; (7) presence of a cream-colored dorsolateral stripe originating on snout, extending to upper eyelid and posteriorly to level of axilla; (8) dorsal surface of skull tightly co-ossified; (9) absence of hand webbing; (10) large toe disc, almost rounded; (11) single subgular vocal sac; (12) ventral surface of thighs and arms brown, sparsely granulated; (13) gular region and venter light gray, moderately granulated and with cream-colored spots; (14) sum of thigh and tibia lengths 89–91 % of snout-vent length.</p> <p> <b>Description of holotype.</b> Medium in size (SVL 60.5 mm). Head slightly longer than wide (HW/HL 0.95). Snout almost rounded in dorsal view, acute in lateral view. Canthus rostralis slightly elevated, almost straight. Loreal region slightly concave. Eyes large (ED/TD 1.6), directed anteriorly. Tympanum round and 1.7 times smaller than eye diameter. Supra-tympanic fold barely distinct, partially covering the tympanum and extending from posterior eyelid margin to posterior margin of tympanic ring. Nostrils in dorsolateral position. Internarial region slightly grooved, laterally delimited by two small bony crests. Skin of dorsal surface of head tightly coossified. Posterior region of head straight. Coanae elliptical. Series of vomerine teeth arranged in two oblique clusters, posteromedial between the choanae, with posterior edges turned to choanae posterior margins and anterior edges turned to the midpoint between them. Fourteen to 16 vomerine teeth on each side. Tongue large, covering almost entire buccal floor. Forearm robust, arm slender. Subarticular tubercles of first, second, and third fingers round, subarticular tubercle of fourth finger bifid; supernumerary tubercles present; palmar tubercles developed, elongated. Fingers without webbing; disks large, almost rounded. Medium-sized legs, considering thigh and tibia lengths. Sum of thigh and tibia lengths 91.9% of SVL. Nuptial pads absent.

Ventral surface light brown with cream-colored spots. Iris red.</p> <p> <b>Color in preservative.</b> Color in preservative similar to color in life. The cream-colored spots become duller, although with no change in the hue; the dark-brown background becomes duller and slightly lighter; and the venter darkens, following the same color pattern of the ventral surface for the thighs and arms.</p> <p> <b>Variation.</b> All specimens from the type series agree in morphology and color. The dorsolateral stripe may extend farther posteriorly on the dorsum. The light and dark ventral spots vary in number and intensity. The males and females have the same color pattern. Sexual dimorphism is evident only in the size: the males are larger than the females (Table 1).</p> <p> <b>Comparisons with other species.</b> <i>Aparasphenodon pomba</i> <b>sp. nov.</b> is readily distinguished from <i>A. brunoi</i> by its slightly elevated canthus rostralis (prominent and elevated in <i>A. brunoi</i>), loreal region slightly concave (loreal region deep and concave in <i>A. brunoi</i>), absence of a prenasal bone (prenasal bone present in <i>A. brunoi</i>), and iris bright red (iris brown, tending to dark red in <i>A. brunoi</i>). <i>Aparasphenodon pomba</i> <b>sp. nov.</b> is distinguished from <i>A. arapapa</i> by the reticulate dorsal color pattern (uniform color pattern in <i>A. arapapa</i>), loreal region slightly concave (loreal region flattened in <i>A. arapapa</i>), medium-sized legs, sum of thigh and tibia lengths 89–91 % of snout-vent length (short legs in <i>A. arapapa</i>, sum of thigh and tibia lengths 78–82 % of snout-vent length), and nostrils in lateral position (nostrils dorsolateral in <i>A. arapapa</i>). <i>Aparasphenodon pomba</i> <b>sp. nov.</b> is distinguished from <i>A. bokermanni</i> by its reticulate dorsal color pattern (uniform color pattern in <i>A. bokermanni</i>), medium size (large size in <i>A</i>. <i>bokermanni</i>, SVL 71-81 mm), subarticular palmar tubercle of Finger IV bifid (subarticular palmar tubercles rounded in all fingers in <i>A. bokermanni</i>), canthus rostralis slightly elevated and almost straight (canthus rostralis prominent in <i>A. bokermanni</i>), supra-tympanic fold barely distinct, extending from the posterior margin of the eyelid to the posterior region of the tympanic ring (supra-tympanic fold thick, distinct and extending from the posterior eyelid margin to the arm insertion in <i>A. bokermanni</i>) and red iris (dark-brown iris in <i>A. bokermanni</i>). <i>Aparasphenodon pomba</i> sp. nov. is distinguished from <i>A. venezolanus</i> by having the snout almost rounded in dorsal view and acute in profile (snout pointed in dorsal view and rounded in profile in <i>A. venezolanus</i>), canthus rostralis slightly elevated and almost straight (canthus rostralis distinct and concave in <i>A. venezolanus</i>), third subarticular tubercle rounded (third subarticular tubercle bifid in <i>A. venezolanus</i>), dorsal surface of thigh with cream-colored reticulate pattern on dark-brown background (dorsal surface of thigh with four dark-brown transverse stripes in <i>A. venezolanus</i>), ventral surface with cream-colored spots (color uniform in <i>A. venezolanus</i>), single subgular vocal sac (paired lateral vocal sacs in <i>A. venezolanus</i>) and red iris (iris grayish with dark vermiculation in <i>A. venezolanus</i>).</p> <p> <b>Geographic distribution.</b> Known only from the type locality, in the Municipality of Cataguases, State of Minas Gerais, southeastern Brazil (Fig. 5).</p> <p> <b>Natural history.</b> The holotype was collected during the day inside a bamboo culm (<i>Bambusa vulgaris</i>) that had a small slit. All paratypes were found active during the night, during or after rains, occupying the same bamboo grove, at heights from 0.8 to 5.0 m. <i>Bambusa vulgaris</i> is native to Asia (Lima Neto 2010); the bamboo grove where the type series was collected has been in the area for about 70 years and its origin is unknown. <i>Aparasphenodon pomba</i> closes its eyes and contracts its body when manipulated (Fig. 4 B). The new species occurs in sympatry with other three hylid species, <i>Hypsiboas faber</i>, <i>Scinax eurydice</i>, and <i>Scinax</i> sp. (gr. <i>catharinae</i>). We did not find <i>A. pomba</i> males in calling activity.</p> <p> <b>Habitat.</b> <i>Aparasphenodon pomba</i> was found in a locality named Sítio Boa Sorte (21º20’20”S, 42º45’43”W; 288 m a.s.l.), which comprises an area of 135.52 hectares located on the border of the municipalities of Cataguases and Dona Euzébia, in the “Zona da Mata of Minas Gerais. This area is within an Atlantic Rain Forest fragment characterized as Submontane Seasonal Semideciduous Forest (Veloso <i>et al.</i> 1991). This region is currently highly fragmented, with mainly pastureland between forest remnants.</p> <p>The forest fragment lies within the Pomba River sub-basin of the Paraíba do Sul River basin. The mean annual rainfall in the region is around 1200 mm, with a rainy season from October to March and a dry season from April to September. The predominant climate is Aw (tropical hot and humid) in the Köppen classification, with an annual mean temperature of 24.5ºC.</p> <p> <b>Remarks</b>. The environment of the only known locality of <i>Aparasphenodon pomba</i> covers only a small area, and its known range is less than 10 km 2 (actually only 1.36 km 2). There are no protected areas close to the <i>A. pomba</i> type locality (Sítio Boa Sorte), a forest fragment that is highly impacted by human activities because of its proximity to the urban area of the municipality of Cataguases. The Atlantic Forest of southeastern Brazil is the most intensively studied region in the country, and since the 1990s areas close to the type locality of this new species have been repeatedly surveyed for amphibians. Apparently, <i>A. pomba</i> is at critical risk of becoming extinct within a very short period of time, as its presumed range is not included in any conservation unit and is entirely within privately owned land.</p> <p> However, the finding of the new species only in a specific climatic conditions and associated with a bamboo grove environment also suggests subsampling in previous studies conducted in the Atlantic Forest in southeastern Brazil. Based on the criteria and categories of the IUCN Red List (Version 3.1, 2007), these data justify the assignment of <i>A. pomba</i> both the Critically Endangered category (CR) as in the Data Deficient category (DD).</p> <p> <b>Etymology.</b> The specific name of the new species, a noun in apposition, refers to its discovery in an Atlantic Rain Forest fragment near the Pomba River, Cataguases, Minas Gerais.</p>Published as part of <i>Assis, Clodoaldo Lopes De, Santana, Diego José, Silva, Fabiano Aguiar Da, Quintela, Fernando Marques & Feio, Renato Neves, 2013, A new and possibly critically endangered species of casque-headed tree frog Aparasphenodon Miranda-Ribeiro, 1920 (Anura, Hylidae) from southeastern Brazil, pp. 583-591 in Zootaxa 3716 (4)</i> on pages 584-590, DOI: 10.11646/zootaxa.3716.4.6, <a href="http://zenodo.org/record/220310">http://zenodo.org/record/220310</a>
A formação do ídolo: o escritor em O Momento literário e A Vida literária no Brasil - 1900
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2010Esta tese propõe uma leitura comparativa entre O Momento Literário, livro de entrevistas feitas por João do Rio, e A Vida Literária no Brasil 1900, de Brito Broca; dois livros citados na historiografia literária por seu valor informativo no que diz respeito à vida literária brasileira do 1900, mas raramente incorporados a esta historiografia. Partindo da descrição de João do Rio do autor como ídolo, esta leitura pretende compor um panorama da literatura brasileira na virada do século XIX para o século XX baseada nas modas literárias, nas palavras de Brito Broca, e nas relações interpessoais dentro da esfera intelectual e letrada do 1900 brasileiro. Em outras palavras, diferente do estabelecimento de escolas literárias e cânones, típicos da historiografia tradicional, que se baseia na figura do autor canônico, esta tese analisa a constituição de uma história literária interpessoal, que molda, em suas repetições, em seus esquemas, e em seus princípios de classificação, assim como nas práticas dos agentes deste campo, a figura do autor como ídolo. A hipótese é que a figura do autor como ídolo é constituída dentro deste panorama momentâneo, principalmente através da mídia, separado do campo institucional ao qual os autores e intelectuais reunidos nos livros de João do Rio e Brito Broca tradicionalmente pertencem. Esta passagem do autor para o ídolo, nesta tese, será analisada principalmente na polarização entre dois autores: Machado de Assis e Olavo Bilac
Ranacephala hogei (Mertens, 1967): novos registros de ocorrência, história natural e subsídios para manejo e avaliação do estado de conservação
No full textHere we present the results of a long-term study on the threatened freshwater turtle Ranacephala hogei (Mertens, 1967). This species is endemic to the Atlantic Forest of southeastern Brazil and occurs in the states of Minas Gerais, Rio de Janeiro, and Espírito Santo. It inhabits the river basins of the Paraíba do Sul, Itapemirim, Lagoa Feia, and Córrego São Salvador. Ranacephala hogei is globally classified as Critically Endangered (CR) and is the only Brazilian chelonian included among the 25 most threatened turtle species worldwide. In addition, it is the first freshwater turtle species in Brazil selected for a captive management program. This prominence reflects the severe threats faced by the species, as its distribution is concentrated in some of the most densely populated regions of the country. Nevertheless, despite its high conservation relevance, R. hogei remains poorly studied, and even basic biological data are scarce. The lack of such information hampers conservation actions, compromises assessments of its conservation status, and weakens the efficient allocation of resources directed toward the species. In this context, we conducted a long-term study to update its geographic distribution and provide data on its natural history, with particular emphasis on coloration. Data collection began in 2016 and involved trapping, visits to scientific collections, literature review, citizen science, and spectrophotometric analyses. Among these approaches, citizen science proved to be particularly important, contributing the majority of occurrence records. Our results increased the number of known occurrence localities by 144%, totaling 45 localities for the species. These records expanded its known distribution, added a new river basin to its range, and revealed populations previously considered extinct. Spectrophotometric analyses showed that, despite its conspicuous appearance, the coloration of R. hogei provides effective camouflage in aquatic environments. The species also exhibits sexual and ontogenetic differences in brightness, with females being brighter than males. We further suggest that its shy behavior is associated with its conspicuous coloration. Overall, our findings provide valuable information that will contribute to future assessments of the conservation status of R. hogei and to the development of effective ex situ management strategies. Keywords: Atlantic Forest; distribution; coloration Chelidae; Testudines; conservation; geographicNa presente tese apresentamos os resultados de um estudo de longo prazo realizado com o ameaçado cágado Ranacephala hogei (Mertens, 1967). Essa espécie é endêmica da Mata Atlântica do Sudeste do Brasil, ocorrendo nos estados de Minas Gerais, Rio de Janeiro e Espírito Santo. Vive nas bacias dos rios Paraíba do Sul, Itapemirim, da Lagoa Feia e do Córrego São Salvador. Ranacephala hogei é mundialmente considerada “Criticamente Ameaçada” (CR), sendo o único quelônio brasileiro incluído entre as 25 espécies de tartarugas mais ameaçadas do planeta. Além disso, é a primeira espécie de cágado do Brasil escolhida para um programa de manejo em cativeiro. Todo esse destaque se deve às ameaças impostas a essa espécie, uma vez que sua distribuição se concentra nas regiões mais populosas do país. No entanto, mesmo com todo esse apelo conservacionista, R. hogei possui grande carência de estudos, e até mesmo dados básicos são escassos. A falta desses dados prejudica as ações de conservação, compromete as avaliações sobre seu status de conservação e fragiliza a alocação eficiente de recursos para a espécie. Diante desse cenário, realizamos uma pesquisa de longo prazo para atualizar sua área de distribuição e fornecer dados sobre sua história natural, com foco em sua coloração. Iniciamos a coleta de dados em 2016, envolvendo capturas com armadilhas, visitas a coleções científicas, revisão de literatura, ciência cidadã e análises de espectrofotometria. Entre esses métodos, a ciência cidadã se mostrou altamente importante, contribuindo com a grande maioria dos registros. Os resultados ampliaram os pontos de ocorrência conhecidos em 144%, totalizando 45 localidades de ocorrência da espécie. Esses registros expandiram sua distribuição, adicionaram uma nova bacia hidrográfica à sua área de ocorrência e revelaram populações previamente consideradas extintas. Em relação à espectrofotometria, os resultados revelaram que a coloração de R. hogei, apesar de chamativa, lhe confere camuflagem no ambiente aquático. A espécie também apresenta diferenças sexuais e ontogenéticas em relação ao brilho, sendo as fêmeas mais brilhantes que os machos. Acreditamos, ainda, que seu comportamento tímido está relacionado às suas cores conspícuas. Por fim, nossos dados trouxeram informações relevantes que contribuirão para futuras avaliações sobre o status de conservação de R. hogei, bem como para seu manejo ex situ.
