Xylomyces is characterized by the absence of conidiomata, conidiophores, conidiogenous cells, and conidia. The genus only produces chains of large, dark, thick-walled, dry, multiseptate chlamydospores with or without constricted septa. During an investigation of aquatic hyphomycetes on submerged wood and leaf litter in a stream in the Brazilian Amazon, we found four of the accepted eight species of Xylomyces. Xylomyces acerosisporus, X. aquaticus, and X. foliicola are new records to the Brazilian Amazon, while X. giganteus is a new record for the southern Amazonian region. Xylomyces giganteus showed the highest relative frequency and occurrence and X. foliicola displayed an intermediate relative frequency and occurrence. Xylomyces acerosisporus and X. aquaticus showed the lowest relative frequency, while X. acerosisporus indicated the lowest relative occurrence. Descriptions, notes, geographic distributions, and illustrations are presented for all species of Xylomyces found in this study. We also provide a key and a table for all species.

ABSTRACT The aim of this study was to investigate the species of conidial fungi associated with leaf litter of Cedrela odorata (Meliaceae), an endangered red cedar species typical of Amazonian terra-firme forests. Conidial fungi were sampled around C. odorata individuals in three forest areas in the municipality of Belém (Pará State, Brazil). A total of 104 species were identified, with 53 new records for the state of Pará, 46 first records for the Brazilian Amazon, including new records for Brazil (Cordana abramovii), for South America (Acarocybiopsis cubitaensis, Xylocladium claviforme) and for the Americas (Dactylaria biguttulata). A review of species of conidial fungi reported on C. odorata is provided, indicating its distribution in Brazil. For each new record in Brazil, South America and the Americas we present a description, illustrations, geographical distribution and taxonomic comments.

ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.

The present study stems from initial efforts in surveying the terrestrial gastropod fauna of Acre state, an undersampled Amazonian region in northwestern Brazil. Herein, we report the first record of the operculate snail Helicina chionea Pilsbry, 1949 in Brazil, alongside the first records of two other helicinids from Acre: H. juruana Ihering, 1905 and H. laterculus F.C. Baker, 1914. With the present new record, there is a total of 38 helicinid species reported from Brazil.

Abstract: The present study aims to document the community composition, abundance, and species richness of saprophytic fly species (Mesembrinellidae, Neriidae, Ropalomeridae, and Sarcophagidae) of the Volta Grande region of the Xingu River, a poorly sampled area impacted by the Belo Monte hydroelectric dam. Five collecting trips were carried out between 2014 and 2016, when traps baited with fermenting bananas were used. A total of 154 specimens, three genera, and six species were collected of Mesembrinellidae; 196 specimens, three genera, and seven species of Neriidae; 272 specimens, three genera, and six species of Ropalomeridae; and 624 specimens, 22 species and 10 genera of Sarcophagidae. Species accumulation curves for all families except Sarcophagidae demonstrated a strong tendency towards stabilization, showing that sampling efforts were sufficient to record most of the targeted species. Laneela perisi (Mariluis, 1987) (Mesembrinellidae) is a new record for the state of Pará. Among Ropalomeridae, Apophorhynchus amazonensisPrado, 1966, is a new record for Pará. Among Sarcophagidae, Helicobia aurescens (Townsend, 1927) is newly recorded from the Brazilian Amazon, and Ravinia effrenata (Walker, 1861) and Titanogrypa larvicida (Lopes, 1935) are new records for Pará.

ABSTRACT (Freshwater hyphomycetes in a preserved insular system from Brazil: first records at Parque Estadual da Ilha do Cardoso, municipality of Cananéia, São Paulo State). To survey freshwater hyphomycetes from insular water bodies at the Parque Estadual da Ilha do Cardoso State Park, in Cananéia municipality, São Paulo State, Brazil, submerged mixed leaf litter samples were collected from six sites from June 2012 to February 2013. The samples were taken to the laboratory and incubated in Petri dishes containing sterile distilled water at room temperature (20oC). From the 5th day on, until at least one month, fragments of the leaf litter samples were examined under the microscope, resulting in the morphological identification of 33 taxa. Among those, two are new records for the state of São Paulo and four for Brazil. Descriptions and pictures of each new record are presented.

Two new species and a new record of Calycomyza Hendel are described for the Brazilian Amazon: Calycomyza rolandrae sp. nov. and Calycomyza dryas sp. nov. This is the first time we recorded Calycomyza hyptisicola Spencer and Calycomyza richardsi (Spencer) in Brazil. These species can be distinguished by the structure of the male terminalia, but the female terminalia can be an important taxonomic character, especially the ninth abdominal sternite, ninth abdominal tergite and the marginal seta.

There are 11 genera of Dorylinae in the Neotropics, but Syscia Roger, 1861 is the only one with a discontinuous distribution between the Nearctic, Neotropical and Indomalayan regions. The present study reports a new record of Syscia in northern Brazil and confirms its distribution in South America, in accordance with previous reports. The Syscia specimens corresponds to an undescribed species and were collected along the margins of the Madeira River, in the National Forest of do Jamari, in the southwestern Brazilian Amazon.

Immature stages of many Brazilian Smicridea species remains unknown, and efforts to describe all life stages are required. In this paper, the larva and pupa of Smicridea (Rhyacophylax) gladiator Flint 1978, associated with adults through the metamorphotype method, are described and illustrated. In addition, the known distribution of this species is extended in the Brazilian Amazon Basin with new records from Amazonas state and the first record in Pará state. Information about its bionomics is also provided.
