Abstract The genus Alterosa Blahnik (2005), with 39 extant species, is endemic to Atlantic Forest areas of southern and southeastern Brazil. Herein, we describe and illustrate two new species from Rio de Janeiro state, southeastern Brazil: Alterosa cornuta sp. nov., easily diagnosed by the horn-like intermediate appendages crossing each other, and A. araras sp. nov., recognized mainly by the extremely developed basodorsal protuberance on tergum X and by the rod-like, mesally curved preanal appendages, with at least 2 stout spine-like setae positioned at mid length and with the apex cupped. Additionally, a new distributional record for Espírito Santo state, southeastern Brazil, is provided for Alterosa falcata Blahnik (2005).

Resumo: Objetivo Este trabalho teve como objetivo examinar a composição e riqueza da assembleia de larvas de Trichoptera em rios na Serra da Bocaina, Sudeste do Brasil, e identificar as principais variáveis ambientais, que afetam os mesmos rios com diferentes condições de uso da terra. Métodos As amostragens foram feitas em 19 riachos em setembro e outubro de 2007. Cada riacho foi caracterizado fisiograficamente, através da aplicação de um protocolo de avaliação ambiental para rios de Mata Atlântica, e parâmetros físicos e químicos. Dos 19 rios amostrados, seis foram classificados como referência, seis como intermediários (moderado impacto antrópico) e sete como pobres (forte impacto antrópico). Em cada riacho, foi feita uma amostragem multi-habitat com uma rede de “kick”. Cada amostra foi composta por 20 unidades, sendo cada uma correspondente a 1 m2 de substrato coletado, totalizando 20 m2 de área amostrada. O material coletado foi colocado em um organizador, lavado, homogeneizado e sub-amostrado, sendo retiradas seis sub-amostras aleatoriamente. Resultados Foram coletadas 2.113 larvas de Trichoptera, pertencentes a 12 famílias e 28 gêneros. Hydropsychidae e Leptoceridae foram as famílias mais abundantes e Smicridea o gênero mais abundante. O índice de Sorensen mostrou que os rios estudados foram agrupados de acordo com a integridade ambiental. Análise de Espécies Indicadoras mostrou táxons característicos apenas para os rios preservados. A CCA mostrou que a assembleia de Trichoptera foi influenciada pela concentração de nitrato, pH e condição da vegetação ripária. A regressão múltipla mostrou correlação significativa da abundância de cinco gêneros com alguma variável ambiental, além da abundância total de Trichoptera. Conclusões Nossos resultados indicaram que o grau de impacto ambiental, principalmente a concentração de nitrato e a condição da cobertura vegetal, agiram como um dos principais fatores em determinar a assembléia de Trichoptera presente nos riachos da Serra da Bocaina, separando os rios ao longo de um gradiente ambiental

Abstract: Aim The goal of this study is to examine the composition and richness of caddisfly assemblages in streams at the Serra da Bocaina Mountains, Southeastern Brazil, and to identify the main environmental variables, affecting caddisfly assemblages at the streams with different conditions of land use. Methods The sampling was conducted in 19 streams during September and October 2007. All sites were characterized physiographically by application of environmental assessment protocol to Atlantic Forest streams and by some physical and chemical parameters. Of the 19 streams sampled, six were classified as reference, six streams as intermediate (moderate anthropic impact) and seven streams as poor (strong anthropic impact). In each site, a multi-habitat sampling was taken with a kick sampler net. The sample was composed by 20 units, each one corresponded to 1 m2 of collected substrate, corresponding 20 m2 of sampling area. The material was placed in a plastic container (500 µm of mesh), washed, homogenized and sub-sampled. For each stream, 6 subsamples were randomly sorted. Results Were collected 2,113 caddisfly larvae, belonging to 12 families and 28 genera. Hydropsychidae and Leptoceridae were the most abundant families, and Smicridea was the most abundant genus. Sorensen’s index results showed that the streams studied were grouped according to environmental integrity. The Indicator Species Analysis showed only characteristic taxa to reference streams. Canonical Correspondence Analysis showed that caddisfly assemblage was strongly influenced by nitrate concentration, pH and condition of riparian vegetation. Multiple regression analysis indicated significant correlations to five genera with some environmental parameters, besides total abundance of Trichoptera. Conclusions Ours results showed that degree of environmental impact, mainly the nitrate concentration, pH, and condition of cover vegetation acted as a major factor in determining the Trichoptera assemblages present in the stream of the Serra da Bocaina, separating streams along an environmental gradient.

Abstract: En | Text: En | PDF: En

Costatrichia Mosely, 1937 is a Neotropical genus included in the subfamily Leucotrichiinae. Previously, this genus included 14 described species, two from Brazil and eight from Costa Rica. Based on recent specimens collected with light traps in the Brazilian Amazon and Costa Rica, we describe two new species: Costatrichia ipixuna sp. nov. from the state of Amazonas, Brazil (C. lodora group) and C. falsa sp. nov. from Puntarenas, Costa Rica (C. simplex group). Costatrichia ipixuna sp. nov. is most similar to C. noite Angrisano, 1995, but can be distinguished by the shallower U-shaped incision on posterior margin of sternum VIII, by the absence of the lateral projection of the same segment bearing very long setae, and by the phallus with a pair of spine-like sclerotized processes apically. Costatrichia falsa sp. nov. is most similar to C. zopilote Harris & Holzenthal, 1999, but differs from it by the median pair of spines of segment VIII, directed mesad and curved posteriorly crossing over each other; by the irregular posterior margin of segment VIII, in ventral view; by the segment X without short lateral paired spines; and by the flange-like apical processes on phallus. In addition, we provide the first record of C. noite Angrisano, 1995 from Brazil (state of Amazonas).

Abstract: En | Text: En | PDF: En

Three new species of Hydroptilidae are herein described and illustrated from specimens collected with light traps in the states of Pará and Rio de Janeiro, Brazil. Flintiella carajas sp. nov., from Floresta Nacional de Carajás, shares with F. panamensis Harris, Flint & Holzenthal, 2002, F. tamaulipasa Harris, Flint & Holzenthal, 2002, F. yanamona Harris, Flint & Holzenthal, 2002, and F. manauara Santos & Nessimian, 2009 a deeply incised phallic apex. However, males can be distinguished by a ventromesal process on segment VII, by lacking dorsal hooked processes on segment IX, by the elongate subgenital plate, and by the lateral lobes of the phallic apex slightly curved laterad. Rhyacopsyche diacantha sp. nov. is closely related to R. yatay Angrisano, 1989 and R. garuhape Angrisano & Sganga, 2009. All three species have complex inferior appendages with ventral and dorsal lobes. The new species is distinguished by the male genitalia with segment X two times longer than broad, inferior appendages with the apices obliquely truncate, and a bilobed dorsal lobe on the inferior appendages. Features of the male genitalia of Rhyacopsyche angra sp. nov., R. hagenii and R. dikrosa are similar, but the first species can be distinguished by the inferior appendages truncate apically and produced laterad, and a phallus with the internal tubule hooked subapically and apically.

O ambiente físico dos rios apresenta diversos desafios para os organismos que vivem sob sua influência. A velocidade da água, um dos fatores mais importantes a atuar nesses ambientes, tem influência local no substrato, temperatura e oxigenação da água. A força da correnteza age determinando a distribuição das espécies e as adaptações morfológicas e comportamentais dos organismos. O objetivo desse estudo foi abordar o tamanho relativo das brânquias de Cloeodes jaragua em dois meso-habitats: um ambiente lêntico (represa) e um ambiente lótico (áreas de correnteza) no Parque Nacional da Serra dos Órgãos - RJ. Um total de 20 indivíduos foi coletado em cada tipo de ambiente e as larguras da cabeça e brânquias foram medidas. O ambiente lêntico apresentou ninfas com medidas mais largas e mais constantes que o ambiente lótico. Este último, apesar de ser composto por ninfas em diferentes estágios de desenvolvimento, apresentou indivíduos com menores larguras de brânquias. Ambos, largura da cabeça e tipo de ambiente, explicaram o tamanho das brânquias, mostrando as condições dos habitats dos rios como importantes modeladores da morfologia desses animais.

Physical environment of streams present many challenging factors to the organisms living under its influence. Water speed, one of the most important factors affecting such environments, has local influence on substrata, temperature, and oxygen levels. It acts determining species distributions and morphological and behavioral adaptations of organisms. The aim of this study was to assess the relative size of gills of Cloeodes jaragua on two mesohabitats: lentic environment (river dam) and lotic environment (fast flowing area of a stream) in Parque Nacional da Serra dos Órgãos (RJ, Brazil). Twenty individuals were collected on each environment and width of the head and gills were taken. Lentic environment showed nymphs with broader and more constant measurements than the lotic environment. The former, despite being composed of nymphs on different stages of development, presented individuals with narrower gills. Both, head width and environment type explained gills size, showing that streams habitat conditions are important in shaping the morphology of these animals.

A família Leptophlebiidae é ainda pobremente conhecida no Estado do Rio de Janeiro, tanto em termos faunísticos quanto taxonômicos e biológicos. No presente trabalho foram reunidos dados biológicos acerca de 14 gêneros (Askola, Farrodes, Hagenulopsis, Hermanella, Hylister, Leentvaaria, Massartella, Miroculis, Needhamella, Perissophlebiodes, Thraulodes, Traverella e Ulmeritoides, além de um gênero ainda não descrito) e em torno de 25 morfoespécies ocorrentes no estado. Em termos ecológicos, a maioria dos gêneros e espécies dessa família está associada a ambientes lóticos ritrais, colonizando áreas de deposição de material orgânico alóctone.

The leptophlebiid mayflies from Rio de Janeiro State are still poorly known from faunistic, taxonomic and biological points of view. In this paper were compiled biological data about 14 genera (Askola, Farrodes, Hagenulopsis, Hermanella, Hylister, Leentvaaria, Massartella, Miroculis, Needhamella, Perissophlebiodes, Thraulodes, Traverella, Ulmeritoides, and an undescribed genus) and about 25 morphospecies from Rio de Janeiro. Most of the genera and species of this family are related to rithral habitats, occupying places with deposition of allochtonous organic matter.

OBJETIVO: O objetivo deste artigo foi estudar a distribuição espacial e a categorização funcional trófica da comunidade de insetos aquáticos de 18 riachos em diferentes altitudes na Bacia do Rio Mambucaba, Serra da Bocaina, Sudeste do Brasil; MÉTODOS: As amostras foram coletadas em dois períodos secos consecutivos (agosto de 2003 e 2004), sendo coletados em quatro tipos de substratos: folhiço em correnteza, folhiço de fundo, pedras e cascalho; RESULTADOS: Foram identificados 75.581 indivíduos de insetos aquáticos pertencentes a 201 táxons. Os substratos com folhiço concentraram a maior parte da fauna (64%), sendo o folhiço em correnteza o substrato com maior abundância de indivíduos (32.572). O cascalho apresentou os maiores valores de riqueza (29,84 táxons esperado em 187 indivíduos; método da rarefação) e diversidade de Shannon (H' = 2,370). A menor riqueza (20,24 táxons) foi observada no substrato pedra. A distribuição dos táxons entre os substratos mostrou 28 táxons restritos a um tipo de substrato, enquanto 78 táxons ocorreram em todos os substratos. Vinte táxons foram indicativos para folhiço de fundo, 26 para folhiço em correnteza, 22 para cascalho e nove táxons para pedra. Em relação aos substratos orgânicos e inorgânicos, 29 táxons foram característicos de folhiço, e 17 de substratos inorgânicos. A análise de classificação baseada no índice de Bray-Curtis e método de ligação UPGMA indicou que os insetos aquáticos se distribuíram em relação ao tipo de substrato e disponibilidade de alimento. Em todos os substratos, a principal categoria funcional foi coletor-catador (40,64%), enquanto fragmentador (6,67%) a menor abundância. ANOVA e Teste HSD de Tukey mostraram que os coletor-catadores e fragmentador foram predominantes nos substratos de folhiço em depósitos, coletores-filtradores nos substrates de correnteza e raspadores nos substratos duros; CONCLUSÕES: Nossos resultados mostraram que independentemente do rio ou altitude, os substratos de um mesmo tipo apresentam assembléias similares. A abundância e a proporção relativa dos grupos funcionais tróficos mostrou variação entre os habitats.

AIM: The aim of this paper was to study the spatial distribution and functional feeding structure of aquatic insect communities of 18 streams at different altitudes in Mambucaba River Basin, Serra da Bocaina, Southeastern Brazil; METHODS: Samples were collected in two consecutive dry periods (August of 2003 and 2004) being sampled four substrate types in each stream: litter from riffles, litter from pools, rocks and gravel; RESULTS: We identified 75,581 aquatic insect individuals belonging to 201 taxa. Most of the fauna was found in litter substrates (64%), and riffle litter substrate had the majority of the specimens (32,572 individuals). Gravel was the substrate with highest values of richness (29.84 taxa expected for 187 individuals; rarefaction method) and Shannon's diversity (H' = 2.370). Rock substrate showed the lowest richness (20.24 taxa). Distribution of taxa across substrates shows that only 28 taxa are restricted to a single substrate, while 78 taxa occurred in all substrates. The indicator analysis showed that 20 taxa were characteristic of pool litter, 25 of riffle litter, 22 of gravel and only nine to rock. In relation to organic and inorganic substrates, 29 taxa were characteristic of litter, and 17 of inorganic substrates. Cluster analysis based on Bray-Curtis dissimilarity index and UPGMA linkage method showed that aquatic insects were distributed according to substrate and food resource. In all substrates, the main functional feeding group was collector-gatherer (40.64%), and the least representative was shredder (6.67%). ANOVA and Tukey HSD tests showed that collector-gatherers and shredders were predominant in pool substrates, collector-filters in riffle substrate and scrapers in hard substrates; CONCLUSION: Ours results show that independently of stream or altitude, substrate of the same type have similar faunal assemblages. The abundance and relative proportion of the functional feeding group showed variation across habitats.

Costatrichia Mosely, 1937 (Leucotrichiini) is for the first time recorded from Brazil. Two new species are described: Costatrichia nelsonferreirai sp. nov. and C. fluminensis sp. nov. from states of Pará and Rio de Janeiro, respectively. Costatrichia nelsonferreirai sp. nov. is similar to C. bipartita Flint, 1970, but can be distinguished from the latter by a pair of ventrolateral bifurcate processes on the posterior margin of male segment VIII. Costatrichia fluminensis sp. nov. is similar to C. simplex Flint, 1970, but the former can be easily distinguished from the latter by a pair of slender lateral processes on the posterior margin of male segment IX and by a spatulate apical process on phallus.

Riqueza de macroinvertebrados aquáticos em riachos ao longo de um gradiente altitudinal no Sudeste do Brasil. Um estudo da riqueza e composição da fauna de insetos aquáticos de uma bacia hidrográfica com ênfase no gradiente altitudinal foi conduzido com o objetivo de testar a hipótese de que existe uma descontinuidade na composição da fauna relacionada à altitude e latitude. Na região Sudeste do Brasil, próxima à latitude 22°, a transição da fauna ritral-potamal deveria ocorrer em torno de 500 m. Com este objetivo central foram estudados 18 afluentes do Rio Mambucaba, Parque Nacional da Serra da Bocaina, SP-RJ, divididos em 6 faixas altitudinais (faixa 1: acima de 1500 m; faixa 2: 1200-1300 m; faixa 3: 900-1000 m; faixa 4: 400-700 m; faixa 5: 100-300 m e faixa 6: 0-100 m), sendo amostrados três riachos por faixa de altitude. Os insetos aquáticos foram identificados até o menor nível taxonômico possível. A maior riqueza foi observada nas altitudes entre 1200-1300 m, enquanto a menor riqueza ocorreu em altitudes inferiores a 100 m. O teste de espécies indicadoras mostrou táxons característicos para quatro das seis zonas altitudinais consideradas no presente trabalho. Os resultados do índice de Similaridade de Sorensen e da CCA mostraram que a comunidade de insetos aquáticos do Parque Nacional da Serra da Bocaina foi influenciada primariamente pela altitude e temperatura mais do que o tamanho do rio. A ausência de táxons indicativos, associada a menor riqueza de táxons e menor abundância entre as altitudes de 400-700 m sugerem uma zona de transição da fauna ritral para a fauna potamal, a qual parece ser distinta a 200 m.

A study concerning taxonomic richness and composition of the aquatic insect fauna in streams within the same catchment basin along an altitudinal gradient in Southeast Brazil, was conducted to test the hypothesis that there is a faunal discontinuity in the biocenotic composition, related to differences in altitude and latitude. In Southeastern Brazil, around latitude 22°, this faunal transition from rhithron to potamon biocenosis should occur at 500 m above sea level. Eighteen tributaries of the Mambucaba River, at Serra da Bocaina National Park, SP-RJ, Brazil, were studied. The streams were separated into 6 altitudinal zones (zone 1: above 1500 m; zone 2: 1200-1300 m; zone 3: 900-1000 m; zone 4: 400-700 m; zone 5: 100-300 m; and zone 6: 0-100 m) each including three streams. The aquatic insects were identified at the lowest possible taxonomic level. The highest richness was observed in altitudes between 1200-1300 m, while the lowest occurred in altitudes below 100 m. The Indicator Value method indicated taxa characteristic for four of the six altitudinal zones considered in this paper. Sorensen's Index and CCA results showed that distribution and composition of aquatic insect fauna of Serra da Bocaina National Park was influenced primarily by altitude and temperature rather than stream size. The absence of indicator species and the lower abundance in altitudes between 400-700 m suggest a transition from rhithral to potamal fauna, which is distinct at 200 m.

Abstract: En | Text: En | PDF: En

The larva and pupa of Leptonema tridens Mosely, 1933 are described and illustrated. Larvae of L. tridens can be distinguished from other described larvae of Leptonema Guérin, 1843 mainly by the rodlike setae of the labrum and the forecoxa lacking processes, bearing only a row of spiniform setae on its inner surface. The specimens were collected in different localities of the Mantiqueira mountain range, Itatiaia massif, states of Minas Gerais and Rio de Janeiro, southeastern Brazil. Larvae build typical hydropsychid shelters and are found in rapids, attached to rocky substrates. Gut content analysis revealed that larvae are omnivorous-filterers.

Os objetivos deste trabalho foram avaliar a riqueza e a diversidade da fauna de Poduromorpha em dois biótopos na Restinga de Maricá, RJ, identificar as espécies características de cada biótopo e determinar as relações da estrutura da comunidade com parâmetros ambientais abióticos. Representantes da ordem Poduromorpha (Collembola) foram estudados do ponto de vista ecológico nos ambientes de vegetação halófila-psamófila reptante e de primeiro cordão arenoso em áreas preservadas da Restinga de Maricá, localizada no Estado do Rio de Janeiro, Brasil. Os maiores valores de diversidade, riqueza e equitabilidade de espécies de colêmbolos foram observados no ambiente de primeiro cordão arenoso. Foram encontradas diferenças nas espécies fundamentais, acessórias e acidentais nos ambientes amostrados. Paraxenylla piloua atuou como indicadora de ambiente da vegetação halófila-psamófila reptante, ao passo que Friesea reducta, Pseudachorutes difficilis e Xenylla maritima mostraram-se indicadoras de ambiente de primeiro cordão arenoso. A análise de correspondência canônica mostrou que os fatores mais importantes na distribuição espaço-temporal das espécies foram pH, conteúdo de matéria orgânica e umidade do solo.

The objectives of this work were to evaluate the richness and diversity of the Poduromorpha fauna in two biotopes in Restinga de Maricá, RJ, Brazil, to identify the characteristic species of each biotope and to determine the relationships between the community structure and the abiotic environmental parameters. Representatives of the Poduromorpha (Collembola) order were studied under an ecological viewpoint in halophyte-psammophyte vegetation and foredune zone in preserved areas of Restinga de Maricá, a sand dune environment in the state of Rio de Janeiro, Brazil. The foredune zone showed the highest diversity, richness and equitability of springtail species. Differences in the fundamental, accessory and accidental species in each environment were encountered. Paraxenylla piloua was found to be an indicator species of the halophyte-psammophyte vegetation, while Friesea reducta, Pseudachorutes difficilis and Xenylla maritima were indicators of the foredune zone. The canonical correspondence analysis indicated pH, organic matter content and soil humidity as the most important factors influencing the spatiotemporal distribution of the species.
