Item Nova subspécie de Caprimulgus (Linnaeus) (Aves, Caprimulgidae) do Espírito Santo, Brasil(Revista Brasileira de Zoologia, 1995) Ribon, RômuloA population of a small and dark nightjar was discovered at Colatina, Espírito Santo, and has been identified by its voice and pattern of coloration as a new subspecies of the Pygmy Nightjar Caprimulgus hirundinaceus (Spix, 1825). This represents a considerable range expansion for this poorly known species, formerly considered endemic to the xeric "caatinga" region of Northeastern Brazil. However, other populations may exist. Colatina's birds live on exposed dark rocks with which their plumage harmonizes.Item Live-trapping Ocelots (Leopardus pardalis): traps, baits, injuries, immobilization and costs(Biota Neotropica, 2017) Perilli, Miriam Lúcia Lages; Matushima, Eliana Reiko; Widmer, Cynthia Elisa; Azevedo, Fernando Cesar CascelliThe capture of wild animals can provide important information on community structure, population dynamics, home range size, activity patterns, habitat use, denning, social behavior and health status. The objective of this study was to describe the method of capture with details on baits, injuries, non-target captures, anesthesia and costs, to evaluate its success as part of a health evaluation program of ocelots in a Brazilian Atlantic Forest Reserve. From a total of 1,011 trap-night effort in 86 days, we had 68 capture events composed of ocelots (22%, n=15) and non-target species (78%, n = 53). We captured 10 individual ocelots in 15 capture events, corresponding to 5.7 days to capture one ocelot. Capture efficiency was 14.8 ocelots/1,000 trap-nights effort. We suggest capture methods should be selected and implemented based on the following criteria: (i) high capture efficiency; (ii) high selectivity; (iii) low injury rate; (iv) high immobilization suitability; and (v) low costs, in order to enable comparisons of studies from different research groups and from different study areas, allowing a deliberate choice of the best method.Item Um novo gênero e espécie de Baetidae (Ephemeroptera) do Estado de Minas Gerais sudeste do Brasil(Iheringia. Série Zoologia, 2003-06-30) Salles, Frederico F.; Lugo-Ortiz, Carlos R.Iguaira gen. nov., type species, I. poranga, sp. nov., based on one nymph from the State of Minas Gerais, Brazil, are proposed. The new taxon is distinguished by the labrum with multiple, unorganized setae dorsally; hypopharynx with three-lobed lingua; cleft mandibular incisors; labium with internally curved paraglossae; labial palps with second segment with strong, apically rounded distomedial process and third segment with truncate medial and apical margins; elongate tarsal claws with minute denticles; and absence of scales and scale bases.Item Levantamento preliminar dos gêneros e espécies de Baetidae (Insecta: Ephemeroptera) do estado de São Paulo, com ênfase em coletas realizadas em córregos florestados de baixa ordem(Biota Neotropica, 2003) Salles, Frederico Falcão; Francischetti, Cesar N.; Roque, Fabio de Oliveira; Pepinelli, Mateus; Strixino, Susana TrivinhoLevantamento preliminar dos gêneros e espécies de Baetidae (Insecta: Ephemeroptera) do Estado de São Paulo, com ênfase em coletas realizadas em córregos florestados de baixa ordem A despeito dos avanços alcançados recentemente com relação ao conhecimento faunístico de Baetidae no Brasil, assim como na Região Sudeste, até o presente trabalho somente três espécies nominais haviam sido registradas para o Estado de São Paulo. Baseados em coletas realizadas em quinze córregos de baixa ordem localizados em seis macro-regiões do estado, os seguintes táxons de Baetidae são reportados: Americabaetis alphus, A. labiosus, A. longetron, Apobaetis fiuzai, Aturbina georgei, Baetodes cf. serratus, Callibaetis sp. 1, Callibaetis sp. 2, Camelobaetidius anubis, Cloeodes irvingi, Cryptonympha sp., Paracloeodes eurybranchus, Waltzoyphius fasciatus e Zelusia principalis.Item Descrição dos adultos de Camelobaetidius billi (Ephemeroptera, Baetidae)(Iheringia. Série Zoologia, 2004-09-30) Salles, Frederico Falcão; Dias, Lucimar GomesThe adults of Camelobaetidius billi Thomas & Dominique, 2000 are described for the first time. They can be distinguished from the other known adults of the genus by the following combination of characters: in males, turbinate portion of the compound eyes orange, abdominal color pattern, and the shape and relative length of the forceps articles; in females by the abdominal color pattern. The specimens were collected at Presidente Figueiredo, State of Amazonas, Brazil, and represent the first report of the species in Brazil.Item Baetidae (insecta: ephemeroptera) de nova xavantina, Mato Grosso, Brasil: novos registros e descrição de uma nova espécie de cloeodes traver(Biota Neotropica, 2004) Salles, Frederico Falcão; Batista, Joana Darc; Cabette, Helena Ramos SoaresStudies carried mainly in the municipality of Nova Xavantina, Mato Grosso State, have lead us to the discovery of several species of Baetidae. While one of them represents a new species of the genus Cloeodes and is herein described, the others represent new records for the state or even for Brazil. The new species, Cloeodes auwe sp. nov., can be differentiated from the other known species of the genus by the following characteristics: body color pattern, long and two-segmented maxillary palp, third segment of labial palp robust and apically truncate, long tarsal claws (0.5 times the length of the respective tarsus), hind wing pads absent, and number of spines on the posterior margin of the third tergite and on the paraproct. Besides this new species, the following taxa of Baetidae were also found: Adebrotus amazonicus, Americabaetis alphus, Apobaetis sp., Aturbina georgei, Baetodes sp., Callibaetis sp.1, Callibaetis sp.2, Camelobaetidius janae, Cryptonympha sp., Harpagobaetis gulosus, Paracloeodes binodulus, Spiritiops silvudus, Waltzoyphius fasciatus, and Zelusia principalis.Item As espécies de ephemeroptera (insecta) registradas para o Brasil(Biota Neotropica, 2004) Salles, Frederico Falcão; Serrão, José Eduardo; Hubbard, Michael D.; Da-Silva, Elidiomar RibeiroUma lista da fauna de Ephemeroptera do Brasil, com todas as espécies, gêneros e famílias registrados para o país é apresentada, incluindo os estados para os quais as espécies estão reportadas assim como a bibliografia pertinente. Comentários acerca do estado atual do conhecimento da fauna brasileira também são tecidos. Até o presente momento 10 famílias, 63 gêneros e 166 espécies estão registrados. As famílias Baetidae e Leptophlebiidae compreendem mais de 50% de todos os registros, enquanto as regiões Norte e Sudeste são significativamente melhor estudadas que as demais.Item Miridae (heteroptera) fitófagos e predadores de Minas Gerais, Brasil, com ênfase em espécies com potencial econômico(Iheringia. Série Zoologia, 2001-11) Ferreira, Paulo S. F.; Silva, Elidiomar R. da; Coelho, Luci B. N.A total of 296 species of Miridae belonging to 17 tribes were recorded from State of Minas Gerais, Brazil. New host plant records include 141 species of 43 orders and 69 families. Of this total, 98.5% of plants have some agricultural, pharmacological or ornamental importance; 29 orders and families of host plants have two or more mirid species.Item Rediscovery of the putatively extinct ant species Simopelta minima (Brandão) (Hymenoptera, Formicidae), with a discussion on rarity and conservation status of ant species(Revista Brasileira de Entomologia, 2008-09) Brandão, Carlos Roberto Ferreira; Feitosa, Rodrigo Machado; Schmidt, Fernando Augusto; Solar, Ricardo Ribeiro de CastroSimopelta minima (Brandão, 1989) was originally described based on four workers collected in soil samples from a small cocoa plantation in Ilhéus, state of Bahia, northeastern Brazil. In the subsequent years after the description, this cocoa plantation was eliminated and the species was then considered extinct by the Brazilian environmental institutions. The recent rediscovery of S. minima workers in subterranean pitfall trap samples from Viçosa, state of Minas Gerais, southeastern Brazil, over 1.000 km distant from type locality, suggests that the rarity and vulnerability status of some ant species may be explained by insufficient sampling of adequate microhabitats, in time and space.Item Key to the genera of Ephemerelloidea (Insecta: Ephemeroptera) from Brazil(Biota Neotropica, 2006) Dias, Lucimar G.; Salles, Frederico F.; Francischetti, Cesar N.; Ferreira, Paulo Sérgio F.A key to the Brazilian genera of Ephemerelloidea, nymphs and adults, belonging to the families Coryphoridae, Leptohyphidae and Melanemerellidae is presented. Currently, seven genera of this superfamily are known in Brazil. The Leptohyphidae is the most representative family, with five genera registered from the country, Leptohyphes Eaton, 1882, Leptohyphodes Ulmer, 1920, Traverhyphes Molineri, 2001, Tricorythodes Ulmer, 1920 and Tricorythopsis Traver, 1958. The families Coryphoridae and Melanemerellidae are monotypic, represented by Coryphorus Peters, 1981and Melanemerella Ulmer, 1920.
