EnglishThe Adolpho Ducke Forest Reserve (ADRF) is a fragment of 10.000 hectares in geographic conflict with the city of Manaus. The knowledge of the diversity of Ephemeroptera in the ADRF is essencial because these organisms are biological important elements as food source and for its potential as indicative of the human disturbances. The objective of this study was to develop a survey of the diversity of Leptophlebiidae from two basins of ADRF, comparing the diversity between basins and the dry and rainy periods 38 points were collected from streams of the Eastern (Ipiranga, Ubere and Tinga) and Western (Acara and Bolivia) ADRF basins with aquatic entomological net (rapiche). To verify differences in the wealth of the two basins and to compare the wealth in the dry and rainy periods it was utilized the Jackknife wealth index. It was colleded 804 larvae of Leptophlebiidae, being identified 368 individuals from seven genera: Hagenulopsis Ulmer (35%; n=128); Thraulodes Ulmer (34%; n=124); Farrodes Peters (13%; n=48); Miroculis Edmunds Jr (12%; n=45); Hydrosmilodon Flowers & Dominguez (5%; n=19); Hermanella Needham & Murphy (0.8%; n=3), Microphlebia Savage & Peters (n=1). It represents the first register of Hydrosmilodon, Hermanella and Microphlebia for the ADRF. In the comparison between the basins East and West, the Jackknifes did not indicate significant difference in the wealth of genera. Hermanella and Hydrosmilodon had not occurred in the West basin and, Microphlebia did not occurred in the East basin, however these absences does not represent significant difference in the taxonomic wealth of the basins. The comparison in the wealth of species of Leptophlebiidae considering the dry and rainy period revealed significant difference. About 68% of the individuals had been collected in the dry period, probably because in this period the water is restricted to the stream channel supplying steady substratum (marginal and leaf litter vegetation) to maintain the fauna. In the rainy period the substratum is carried down stream by torrents being impossible to maintain the fauna. portuguesA Reserva Florestal Adolpho Ducke (RFAD) e um fragmento de 10.000 hectares em conflito geografico com a cidade de Manaus. O conhecimento da diversidade dos Ephemeroptera na RFAD e fundamental uma vez que estes organismos sao elementos biologicos importantes; como importante fonte de alimento e, por seu potencial como indicadores das perturbacoes antropogenicas. Neste estudo teve-se como objetivo o levantamento da fauna de Leptophlebiidae (Ephemeroptera) das duas bacias hidrograficas, comparando a diversidade entre as bacias e entre os periodos seco e chuvoso. Coletou-se em 38 pontos dos igarapes das bacias Leste (Ipiranga, Ubere e Tinga) e a Oeste (Acara e Bolivia) da RFAD com rede entomologica aquatica (rapiche). Para verificar diferencas na riqueza das duas bacias e, comparar a riqueza nos periodos seco e chuvoso foi feito o Indice de Riqueza de Jackknife. Foram obtidas 804 larvas de Leptophlebiidae sendo identificados 368 individuos e reconhecidos sete generos: Hagenulopsis Ulmer (35%; n=128); Thraulodes Ulmer (34%; n=124); Farrodes Peters (13%; n=48); Miroculis Edmunds Jr (12%; n=45); Hydrosmilodon Flowers & Dominguez (5%; n=19); Hermanella Needham & Murphy (0.8%; n=3), Microphlebia Savage & Peters (n=1). Este representa o primeiro registro de Hydrosmilodon, Hermanella e Microphlebia para a RFAD. Na comparacao entre as bacias Leste e Oeste, o Indice de Riqueza de Jackknife nao indicou diferenca significativa na riqueza de generos. Hermanella e Hydrosmilodon nao ocorreram na bacia Oeste e, Microphlebia nao ocorreu na bacia Leste, no entanto estas ausencias nao representam diferenca significativa na riqueza taxonomica das bacias. A comparacao na riqueza de especie de Leptophlebiidae considerando o periodo seco e chuvoso revelou uma diferenca significativa entre os periodos. Cerca de 68% dos individuos foram coletados no periodo seco provavelmente porque neste periodo a agua fica restrita ao canal do igarape fornecendo substrato estavel (vegetacao marginal e folhico) para a manutencao da fauna. No periodo chuvoso o substrato e carreado pelas enxurradas nao sendo possivel ? manutencao da fauna.
