| Collections were made during one year, between August 2005 and July 2006, in Malinalco, State of Mexico, in three sites of tropical deciduous forest, a pasture and a induced forest of pine-oak, established in a altitudinal gradient ranging from 1,253 m to 2,300 m. The total of 7,680 specimens Scarabaeidae, Silphidae and Trogidae were captured through NTP-80, representing 18 genera and 38 species. Onthophagus and Canthon contained 46% of the richness of Scarabaeidae. The more distant sites were complementary in their species composition. The lowest complementarity occurred between sites with tropical deciduous forest. It revises the material collected through pitffal traps and light traps funnel type, increasing the list of 38 to 50 species in the study... |

| ABSTRACT A new species of catfish is described from the Esmeraldas River Basin, Pacific slope, northern Ecuador. Tentatively included in Microglanis, represents the second species of the genus inhabiting the Trans-Andean region. The new species is distinguished from known congeners by a unique combination of external characteristics: head and body color pattern, uniform, pale brown, yellowish or grayish, without any kind of blotches, bands or dots, only a lunate transverse band, dark or black, at caudal-fin origin; adipose-fin origin and forward without lighter or luminous areas. Compared with M. variegatus, the new species has morphometric differences, such as the distances between dorsal and pelvic fins, and between posterior nostrils. Some osteological... |

| ABSTRACT Diversity patterns and their causes remain important questions, especially for ecosystems that preserve natural conditions. This is the case of fish diversity in large Neotropical rivers. In this context, we investigated fish diversity patterns along an extensive unregulated river section (ca. 450 km) in the Middle Uruguay River Basin. Sampling was conducted seasonally between May 2017 and March 2018, at six sites (patches) with contrasting environmental conditions. We collected 3,008 individuals belonging to 90 species. Nine were migratory, which summed relevant biomass in local assemblages (20 to 60%). We observed spatial variation in assemblage structure, but weak seasonal effects. Overall, biomass was similar among sites, but richness tended... |

| ABSTRACT Historical information on the probable type-locality of Pimelodus quelen and of its four junior synonyms that share the same neotype, Pimelodus namdia, Pimelodus sebae, Heterobranchus sextentaculatus, and Silurus rivularis, is presented and discussed. The neotype designation for those four species is deemed invalid for not complying with the provisions of the International Code of Zoological Nomenclature, making it technically possible to revalidate any of the four taxa from the synonymy of Rhamdia quelen without having to address the International Commission of Zoological Nomenclature. The type-locality of both Curimata gilbert and Callichthys asper are also restricted to rio Macacu at the village of Japuíba, State of Rio de Janeiro, Brazil. |

| The structure of the fish communities of a pool and a rapid in the ribeirão Santa Bárbara is described. This stream of 5th order is a direct tributary of the rio Tietê in the system of the upper rio Paraná. Thirty three species, from nine families and three orders, were referred in the two mesohabitats: the pool with 31 species, and the rapid with 18. Orders Characiformes, Siluriformes, and Perciformes presented the greatest number of species in the two mesohabitats. The families Characidae and Loricariidae were the most specious, followed by Cichlidae in the pool, and by Parodontidae in the rapid. Most species were accidental, 17 in the pool, and 10 in the rapid, and only six were constant in the two mesohabitats. The greatest diversity and evenness... |

| Nematode species from three intertidal assemblages (St Lawrence Estuary, Quebec, Canada) were studied in order to form an ecological interpretation of three allometric attributes: body width, size spectra, and morphotypes. The three assemblages were characterized by a very similar sediment grain median (Md) but different silt-clay proportions: A1 (upper-tidal level; Md=122 µm; silt=34.8%), A3 (mid-tidal level; Md=182 µm; silt=12.8%), and A5 (lower-tidal level; Md=122 µm; silt=6.8%). Silt-clay proportions were an influential factor in determining the mean nematode body width, used as a morphological discriminant between burrowing and interstitial organisms. A plot of the number of species vs the body width-classes showed two peaks: between 19.3 and 22.6 µm... |

| Nematodes from the sediments of the Swartkops estuary in Port Elizabeth, South Africa were investigated at 10 selected sites along a salinity gradient in the subtidal region at neap tide. The relation between nematode density, genera, community structure and environmental parameters including concentrations of seven heavy metals, Mn, Ti, Cr, Pb, Fe, Sn and Zn in the sediment were investigated. The nematode community structure was significantly influenced by the chlorophyll a concentration and sediment particle-size distribution. The number of genera had significant negative correlation with chlorophyll a and two heavy metals, Fe and Zn in the sediment. The habitat preferences of the genera were also assessed. A combination of the Shannon-Wiener Diversity... |

| Realizou-se a análise faunística de gafanhotos coletados em três constituições vegetais da Flona de Chapecó. Coletas semanais foram realizadas em áreas de eucalipto, mata nativa e pinus durante o período de dezembro de 2003 a dezembro de 2004. Utilizaram-se armadilhas do tipo “pitfall”, rede de varredura, guarda-chuva entomológico e “malaise”. A fauna encontrada nas diferentes áreas foi caracterizada por meio dos índices de abundância, constância, dominância e frequência. Dezoito espécies foram comuns para as três áreas. As espécies Staurorhectus logicornis logicornis, Cylindrotettix sp. e Ommexecha virens ocorreram apenas em eucaliptos e pínus, enquanto, Scotussa lemniscata e Zoniopoda tarsata ocorreram para eucaliptos e mata nativa enquanto Amblytropidia... |

| ABSTRACT Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differences on nesting between interior and edge transects. A sum of 1,500 trap nests was made with bamboo cane internodes and two consecutive years were monitored. In the first year 46 nests were occupied by Pachodynerus grandis (19 nests), Pachodynerus guadulpensis (19), Centris analis (two), and Centris tarsata, Megachile fiebrigi, Megachile guaranitica, Megachile susurrans, Trypoxylon sp and Zethus smithii with one nest each. No statistical differences were found between interior and edge transects... |

| Data on Neotropical coleopterous galls were compiled from the literature, which showed that 82 galls have so far been recorded among 77 plant species. The Fabaceae and Asteraceae plant families display the greatest richness in galls. Most galls are induced on stems or buds, while leaves constitute the second most attacked plant organ. Only 16 coleopteran gallers have been identified at the species level; most records are presented at the order level. The identified species belong to four families: Apionidae, Buprestidae, Curculionidae and Erirhinidae. The galls are found in Argentina, Brazil, Belize, Chile, Colombia (probably), Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama and Venezuela. Eighteen species of Coleoptera are... |

| The multicolored Asian lady beetle, Harmonia axyridis (Pallas, 1773), was first recorded in Brazil in 2002 in Paraná state and subsequently observed in Santa Catarina, Rio Grande do Sul and Minas Gerais. This species can spread to new areas and become dominant in the local community, reducing the density and diversity of native species, mainly Coccinellidae. The objective of this work was to record for the first time the occurrence of H. axyridis in the Federal District and its co-occurrence with other Coccinellidae species. The individuals were collected directly from plants at an organic farm in Taguatinga and in experimental fields of Embrapa Hortaliças, located in the Federal District, from August 2008 to January 2010. We collected 881 Coccinelids, and... |

| Abstract Ilha Grande is a large continental island (total area of 19,300 ha) situated at the southern coast of the state of Rio de Janeiro, in southeast Brazil, within the Atlantic Forest Biome. Here we provide an update to the previous knowledge of the fauna of amphibians and reptiles occurring in Ilha Grande, based on primary data from our own fieldwork and on secondary data (from institutional collections and from the literature). We report the occurrence at Ilha Grande of a total of 74 species, being 34 amphibians (all of them anurans) and 40 reptiles (27 snakes, 11 lizards, one amphisbaenian and one crocodylian). Our survey added 14 species to the herpetofaunal list of Ilha Grande (three of amphibians and eleven of reptiles) and removed one species... |
