A new long-horned Caddisfly in the genus Triplectides Kolenati (Trichoptera: Leptoceridae) from the Itatiaia massif, southeastern Brazil
Dumas, Leandro L;Nessimian, Jorge L;
Neotropical Entomology , 2010, DOI: 10.1590/S1519-566X2010000600016
Abstract: triplectides itatiaia sp. nov. is described from specimens collected on the itatiaia massif, mantiqueira mountain range, rio de janeiro state, brazil. the new species can be distinguished by the presence of hind wing fork i petiolate, the long dorsal excision of segment x and the flat, apically rounded mesal lobes. female and immature stages are unknown. a key to the brazilian species in the genus is provided.

Abstract: small streams, at the biological dynamics of fragmented forest project - inpa ca. 80 km north from the city of manaus (amazonas, braszil) , were studied concerning the composition of the aquatic insects communities in different substrates. in each one of the 20 stretches, four samples of the principal biotopes were collected: leaf litter in riffle areas, leaf litter deposited on the botton of the stream, sand and roots/vegetation on marginal banks.the aim of this study were to evaluate the aquatic insect fauna and relate it with specific substrates inside the igarapé. leaf litter in riffle presented high richness number (106) while sand showed the lowest value (55). higher similarity values occurred between leaf litter deposited on the botton and marginal roots/vegetation. lower values occurred between leaf litter in riffle and sand substrates. some collected taxa were considered indicators of one type of substrate, but there were some taxa that showed no preference. the indicator taxa occurred in riffle litter were found in deposited leaf litter in southeast streams of brazil. this indicates the current velocity may be responsible for the community established. the size of the stream is related to the order and flow regime. in this study bigger streams (presenting higher values of flow and order) showed more distinct communities in each substrate than the smaller ones.
Variation and life strategies of the Trichoptera (Insecta) larvae community in a first order tributary of the Paquequer River, Southeastern Brazil
HUAMANTINCO, A. A.;NESSIMIAN, J. L.;
Revista Brasileira de Biologia , 2000, DOI: 10.1590/S0034-71082000000100010
Abstract: the trichoptera fauna was sampled in a first order tributary of paquequer river, in the district of teresópolis, rio de janeiro state. quantitative samples of litter from pools, litter from riffles, sand, and stones were taken on each season from february 1991 to february 1992.the life cycles of common genera were categorized into three groups of biological strategies. the largest group represented the general profile of the community, in which ultimate instar larvae were predominant in spring and the younger ones in summer. probably, emergence and oviposition occur in spring.
Larvas de Chironomidae ( Diptera) em depósitos de folhi?o submerso em um riacho de primeira ordem da Mata Atlantica (Rio de Janeiro, Brasil)
Sanseverino, Angela M.;Nessimian, Jorge Luiz;
Revista Brasileira de Entomologia , 2008, DOI: 10.1590/S0085-56262008000100017
Abstract: we investigated the fauna of larval chironomidae in accumulations of submerged organic matter (litter) in a first-order stream in the mountain region (about 1000 m a.s.l.) of rio de janeiro state. the chironomidae fauna of submerged litter was quantitatively sampled during autumn, winter, spring and summer. litter fragmentation was estimated and the presence of leaves, wood, roots and fruits was investigated. variations in the chironomid fauna composition and litter structure were studied, and hypotheses about factors influencing chironomid in these litter accumulations were proposed. the subfamilies chironominae, orthocladiinae and tanypodinae were present and frequency participation of each subfamily and genus was calculated for each season. the chironominae and orthocladiinae were identified to genus level, and a total of 23 genera were found. lauterborniella, polypedilum and tanytarsus were the most abundant genera. we observed a variation in the submerged litter structure among seasons, which is probably influenced by geological and climatic factors (mainly precipitation) affecting the drainage basin. the structure of the chironomid fauna changed during the studied period, with genera varying in participation and occurrence among the four seasons. climatic effects on riparian vegetation and on stream physical characteristics were discussed in order to elucidate their influence on submerged litter accumulations and the chironomid fauna structure.

Abstract: a new species of contulma flint (trichoptera, anomalopsychidae) from southeastern brazil. contulma sana sp. nov. is described and illustrated based on specimens collected in the rio macaé basin, macaé, rio de janeiro state, brazil. the new species can be distinguished from congeners by the following male genitalia characters: long posterior lobes, dorsomedian processes of segment ix diverging on apical third, and well developed phallotremal sclerite. the female and immature stages are unknown.

Aspectos da biologia de Buenoa platycnemis (Fieber) (Insecta, Heteroptera, Notonectidae) da Restinga de Maricá, Rio de Janeiro
Nessimian, Jorge Luiz;Ribeiro, José Ricardo Inácio;
Revista Brasileira de Zoologia , 2000, DOI: 10.1590/S0101-81752000000100020
Abstract: a monthly quantitative study on b. platycnemis (fieber, 1851) was carried out in a sand dune marsh, on the littoral of rio janeiro state. the aims of this study were to correlate the life cycle of the species with the seasonal regime of the water body, defining steps of the annual cycle, age strueture, and to indicate oviposition sites and trophic relations. the species shows a marked seasonal tendency. the major steps of the life cycle obtained were an invernal (weak) with a predominance of imagines, followed by another of population expansion, characterized by the absence of adults, massive eclosions and predominance of low instar nymphs. probably, b. platycnemis has a sensibility to water levei variation and might be intluenced by the concentration of spirogyra sp. (chlorophyceae) in the water column. in relation to oviposition, b. platycnemis has not shown preference for any macrophyte, since eggs were found in rhynchosphora corymbosa (linnaeus) britton (cyperaceae), eleocharis sellowiana kunth. (cyperaceae) and nymphoides indica (linnaeus) o. kuntze. (menyanthaceae). the observed predators of b. platycnemis were anax amazilli (burmeister, 1839) (aeshinidae), eryihemis crédula (hagen, 1861) (libellulidae) and other odonata, nymphs and adults of belostoma candidulum montandon, 1903 (belostomatidae), notonecta (paranecta) disturbata hungerford, 1926, buenoa antigone antigone (ki-rkaldy, 1899) (notonectidae), besides curicta cf. tibialis (martin, 1898) and ranatra horvalhi montandon, 1910 (nepidae). larvae of sayomyia sp. (chaoboridae), chiro-nomus spp. and labrundinia sp. (chironomidae), callibaetis gutlatus navás, 1915 (baetidae), cladocerans and copepods are potential prey of b. platycnemis, while ostracodes were refused.
