Range extension for buff-fronted owl Aegolius harrisii in south-east Brazil.

Buff-fronted Owl Aegolius harrisii is a poorly known species. Field records are rare and sparse, with large gaps throughout its distribution. We present five new records of A. harrisii in south-east Brazil, in the states of São Paulo and Minas Gerais, and the second ever nest description. In São Paulo, records from Franca are >300 km from previous records, while the new record in Minas Gerais is 600 km from the only previous state record. More nocturnal field work is required to better evaluate the true distribution of A. harrisii.

Culicidae (Diptera) em área de barragem em Santa Catarina e no Rio Grande do Sul

The Culicidae composition of the Barra Grande Lake Situated between the Municipalities of Esmeralda (Rio Grande do Sul State) and Anita Garibaldi (Santa Catarina State) was assessed by monthly samplings. Twenty-four species were identified from a total of 1, 185 specimens (74.7% as adults and 25.3% as immatures), with Aedes fluviatilis Lutz as the most frequent species. Several species are new records, and some of them are of public health interest. It is suggested that local environmental changes may alter the relationship between humans and vector mosquitoes.

Novos Registros sobre Meloidogyne mayaguensis no Brasil e Estudo Morfológico Comparativo com M. incognita

Almeida, E.J., P.L.M. Soares, A.R. Silva & J.M. Santos. 2008. New records on Meloidogyne mayaguensis in Brazil and comparative study with M. incognita. Meloidogyne mayaguensis is the plant-parasitic nematode responsible for a great impact on guava production in Brazil, since it has been the cause for eradication of thousand of hectares of guava plantations in the Northeastern region. In the present study, this species was detected in soybean fields of Ituverava municipality, São Paulo state, and in different vegetable crops (lettuce, cucumber, pepper and cherry tomato) in Chapada dos Guimaraes municipality, Mato Grosso state, causing root galls and other symptoms. The species was identified on the basis of the perineal pattern of females, and on the morphology and morphometry of anterior region of males. Isozyme phenotype for esterase was used for confirmation. This constitutes the first report on the occurrence of M. mayaguensis on lettuce, cucumber, pepper and cherry tomato cultures in Mato Grosso state and the first one in soybean in São Paulo state. It was found that morphological features of male anterior region and female perineal pattern are enough for the safe distinction between M. mayaguensis and M. incognita.

Ampliação da distribuição geográfica de três caranguejos majóideos (Crustacea, Decapoda, Brachyura) na costa do Estado de São Paulo, Brasil

This study reports range extensions of three species of crabs to the northern coast of the state of São Paulo. The species obtained were Inachoides forceps, Microphrys antillensis and Mithraculus sculptus. Recent new records of marine species in Brazilian waters illustrate the importance of continuous investigations on the biodiversity of subtidal rocky bottoms.

Additions to the known distribution of Epipompilus aztecus (Cresson, 1869) and E. excelsus (Bradley, 1944) (Hymenoptera: Pompilidae)

Knowledge about the species distribution of Epipompilus Kohl, 1884, is largely based on the records from the species description. Recent efforts in South American bodiversity studies indicate that knowledge about the distribution of Epipompilus species in the region is in an early stage. Two new records of E. aztecus were obtained for the semideciduous Atlantic Forest, in central Brazil, and one record for the Amazonian Forest in northern Brazil, indicating that its distribution extends between Central and South America. The new records of E. excelsus were obtained mainly from the Atlantic Forest highlands, indicating that this species is commonly found in the southeastern South American Central Plateau and restricted to forest ecosystem of this region. © 2010 Eduardo Fernando dos Santos and Fernando Barbosa Noll.

Amphibia, anura, hylidae, hypsiboas raniceps cope, 1862: Distribution extension

Hypsiboas raniceps is a large treefrog typically found in the Cerrado and Caatinga biomes. Here we provide information about new records of this species in the Atlantic Forest and raise some hypotheses that could explain the late record of this species in this biome. © 2010 Check List and Authors.

Rhizoctonia solani AG groups in northeast India

Rhizoctonia solani isolates collected from different crops in northeast India belonged to anastomosis group AG 2-2 IIIB (Canavalia ensiformis, Sechium edule, Glycine max and Dolichos lablab). AG 11A was detected on Zea mays, Rhizoctonia solani on Sechium edule and AG 4HG-II on a weed, Galinsoga parviflora, which are new records from India. © Australasian Plant thology ociety 2010.

First record in midwestern region of the state of são paulo, brazil of typhlops brongersmianus vanzolini, 1976 (squamata: Typhlopidae)

In this study we report on two new records of the blindsnake Typhlops brongersmianus for the municipality of Bauru, midwestern region of the state of São Paulo, Brazil. These records expand the geographic distribution currently known for this species in the state and contribute to the knowledge of snakes in southeastern Brazil. © 2011 Check List and Authors.

Helminth parasites of hypsiboas prasinus (Anura: Hylidae) from two atlantic forest fragments, São Paulo State, Brazil

Seventy-seven males of Hypsiboas prasinus from 2 Atlantic forest fragments in the municipalities of Botucatu and Jundiaí, São Paulo State, Brazil, were examined for endoparasites. The frogs were captured in summer (January until March) and winter (July/August) of 2008 and 2009. Thirty-three males (75) from Botucatu were infected with Rhabdias cf. fuelleborni, cosmocerciid nematodes, and Cylindrotaenia americana. Twenty-five tree frogs (78.5) from Jundiaí were infected by Rhabdias cf. fuelleborni, Physaloptera sp., and cosmocerciid nematodes. Only cosmocerciid nematodes presented a statistically significance difference in prevalence (z 4.345; P < 0.001) and mean abundance (t 562.0; P < 0.001) between Botucatu and Jundiaí during the winter. Also, the cosmocerciids exhibited higher mean abundance (t 196.0; P 0.034) in winter when compared with summer at the Jundiaí site. Moreover, to our knowledge, this is the first report of C. americana in the Brazilian Hylidae. This study presents 4 new records of nematodes in H. prasinus. © 2012 American Society of Parasitologists.

Diatomáceas de lagos rasos do pantanal da nhecolândia, área úmida Brasileira

The diatom flora of the shallow lakes in the Pantanal of Nhecolândia is poorly known. Thus, our aim was to know the diatom biodiversity in three types of shallow lakes called baías, salitradas and salinas, characterized by differences in pH, electrical conductivity, contact with the coalescent system and the presence of macrophytes. The samples were collected in dry and rainy seasons, from 2004 to 2007. For taxonomic identification, the material was cleaned with H2O2 and analyzed using light microscopy. A total of 23 diatom species were identified and each lake presented a unique species richness and composition. The greatest species richness was found in the Baía da Sede Nhumirim (21 species), followed by the Salitrada Campo Dora (8 species) and finally the lowest species richness was observed in the Salina do Meio (3 species). Only Anomoeoneis sphaerophora Pfitzer var. sphaerophora and Craticula cf. buderi (Hustedt) Lange-Bertalot occurred in the three studied systems. Except for Eunotia binularis (Ehrenberg) Souza and Aulacoseira ambigua (Grunow) Simonsen, all the others are new records to the Brazilian Pantanal.

Paratrichodina africana (Ciliophora): A pathogenic gill parasite in farmed Nile tilapia

Trichodinids are ciliated protozoa that are widely known as one of the main groups of fish parasites. The genus Trichodina presents the greatest species diversity. However, records of Paratrichodina species are scarce, and little is known about their pathogenicity in hosts. The present study provides new records of Paratrichodina africana Kazubski and El-Tantawy (1986) in Nile tilapia from South America and descriptions of pathological changes and seasonality. A total of 304 farmed fish were examined. From gill scraping, parasites were identified using Klein's nitrate impregnation method. Gill samples were fixed for histopathological analysis. Small trichodinid found in this study have a prominent blade apophysis and narrow central part and blade shape that corresponds to the characteristics of P. africana Kazubski and El-Tantawy (1986). Gill lesions were proportional to parasite intensity, in which the gill tissue was compromised in heavy infestation. Proliferative disturbances were found, including epithelial hyperplasia, desquamation, and mononuclear and eosinophilic infiltrate that culminated in necrosis. We did not observe a seasonality effect on the occurrence of P. africana. This ciliated protozoan causes compromised respiratory capacity that leads to severe gill lesions and currently is an important pathogen that afflicts intensive tilapia cultures in Brazil. © 2013 Elsevier B.V.
