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.

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.

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.

Reproductive Characters

ABSTRACT The first record of Phyllanthus chacoensis for the Brazilian Amazon is presented, based on a specimen from Rondônia state. The species can be recognized by its cauliflorous inflorescence, staminate and pistillate flowers with 4 sepals, devoid of a floral disk, 4 stamens, 2-carpellary ovary, drupaceous, ellipsoidal fruits, with one seed per locule. The species was previously known only from the central-western and northeastern regions of the Caatinga and Pantanal domains in Brazil. We provide a list of synonyms, a detailed description, an updated geographic distribution map in Brazil, data on habitat and conservation status, illustrations of its reproductive characters, and detailed photographs. We also propose a lectotype for the species.

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.

We report a new record for the bushy-tailed opossum Glironia venusta Thomas, 1912 and the water opossum Chironectes minimus (Zimmermann, 1780) in the Floresta Nacional de Carajás, municipality of Parauapebas, state of Pará, Brazil (06°03’00” S, 50°15’00” W). This study represents the second record of Glironia venusta, but the first voucher specimen for eastern Brazilian Amazon. For Chironectes minimus, this record extends the range of the species 558 km southeastwards from the closest known locality in Pará.

Phimophisguerini Duméril, Bibron & Duméril, 1854 is a Xenodontinae snake distributed in Argentina, Brazil and Paraguay. In Brazil, the species is broadly distributed, occurring mainly in open areas of the Cerrado, but also in the Amazon, Atlantic forest and Caatinga. We provide a new record for this species from the municipality of Santarém in the western portion of the state of Pará (Brazil). Five specimens were collected in a small area covered with Amazonian Savanna vegetation. We also provide the description of the morphological variation for the collected specimens. The new record extends the northern limit of the distribution by some 640 km (from Floresta Nacional de Carajás, Parauapebas municipality, eastern Pará). The record from Santarém provides a third locality for P.guerini within the Amazon biome and supports the hypothesis of a past ecological corridor linking the Cerrado and the open habitats within the Amazon.
