Aquatic ecosystems in tropical forests have a high diversity of microorganisms, including fungi, which are important decomposers of submerged wood. Despite the importance of their role in decomposition, research concerning the diversity of freshwater fungi from Brazilian Amazonian environments is scarce. The aim of this work was to describe the composition and diversity of fungi present on submerged wood in two lakes of the Brazilian Amazon (State of Pará). Fragments of decaying wood (30 samples per lake) were collected from the Lakes Juá and Maicá. The wood samples were inspected for 6 months in the presence of fungal reproductive structures. Fungi observed in the wood were identified morphologically. Twenty-three taxa were identified in the Lake Juá (10 sexual and 13 asexual) and 26 taxa in the Lake Maicá (17 sexual, 9 asexual). ITS sequences were obtained for 14 taxa to aid in identification. In the Lakes Juá and Maicá, the diversity indices were H': 2.6514 and H': 2.8174, respectively. The Sørensen index of the fungal communities in the studied lakes was 0.3673. This study is the first to describe the fungal biodiversity of two important aquatic environments in Pará, Brazil.

Resumo. Duas novas espécies de insetos predadores e bioindicadores da qualidade da água do gênero Palpomyia, grupo distincta, são descritas e ilustradas baseadas em espécimes machos. Os imaturos das espécies Palpomyia amazonensis sp. nov. e Palpomyia lanceolata sp. nov. foram coletados em armadilhas ovitrampas e criados em laboratório até adultos. Ambas novas espécies são semelhantes a Palpomyia guyana Clastrier, 1992 e Palpomyia turnbowi Grogan et al., 2013 e diferem de Palpomyia versicolor Macfie, 1939, única espécie do grupo distincta descrita na Amazônia Brasileira. Com as duas descrições, foram aumentadas para três o número de espécies para a Amazônia e 32 para o Brasil.Descrição de duas novas espécies de Palpomyia Meigen (Diptera: Ceratopogonidae) da Amazônia brasileiraAbstract. Two new Amazonian predaceous midge of the genus Palpomyia, from the distincta group, were described based on male specimens. This genus is an important bioindicator of aquatic environments. The immatures of Palpomyia amazonensis sp. nov. and Palpomyia lanceolata sp. nov. were collected with ovitraps and reared in laboratory until adulthood. Both new species are similar with Palpomyia guyana Clastrier, 1992 and Palpomyia turnbowi Grogan et al., 2013 but differs from Palpomyia versicolor Macfie, 1939, the unique species described in Brazilian Amazon until now. With the description of these new species we increase to three the representative species of the distincta group in the Brazilian Amazon and to 32 the number of Brazilian species of Palpomyia.

Definition Of

In the red list of threatened species of Pará State, in Brazil, the salamander Bolitoglossa paraensis was listed as vulnerable. Initially the species was considered a synonym with Bolitoglossa altamazonica, but was recently revalidated. This note discusses the validity of the specimens from the west of the Brazilian Amazon identified as B. paraensis. It is also discussed the categorization of the species as vulnerable, and the records of the species was mapped in the Endemism area Belém. In order to establish a Private Natural Reserve (RPPN), a herpetological survey was carried out in different landscape units of the Nova Amafrutas, in Benevides (Pará), and the records of B. paraensis were mapped in these landscape units. By comparing the abundances recorded by Crump (1971) and those results of the present study, suggested that this species is tolerant to antropic “capoeira” forest (old fallows) next to undisturbed forest. More molecular phylogeographic studies are needed in order to establish a stable the taxonomy status for B. paraensis, and also the definition of its real endemic status in the Center of Endemism of Belém.
