Currently, due to deforestation, only 22% of the original cover remains, and only 7.5% well preserved. Despite the global importance of this biome, it still lacks basic studies, e.g. primary inventories. Cerambycidae is one of the most diverse groups of beetles, with high ecological and economic importance. The aim of this work was to survey the longhorn beetles (Cerambycidae) in three fragments (Pacangê, Vila 5 and Pancada Grande) of Atlantic Forest within Reserva Ecológica da Michelin (southern Bahia State, Brazil). A total of 166 individuals belonging to 53 species were recorded, 15 of them new geographical records for the state, and one for Brazil. The Shannon index (H) shows Pacangê (H = 2.665) as the most diverse fragment, followed by Pancada Grande (H = 2.658) and Vila 5 (H = 2.565). The most abundant species were Nyssodrysina lignaria (38 specimens collected), followed by Compsibidion vanum (31 specimens). One hundred and ten specimens were captured in Malaise traps, while in light traps only 56 specimens were caught; however, the richness and consequently the diversity in light traps was higher. This is one of the few studies carried out in Atlantic Forest surveying longhorn beetles, and provides primary data on these taxa, to help develop conservation policies for this threatened biome.

Many types of injuries can cause different artifacts, which deserve attention of the forensic pathologists when evaluating corpses, either at the crime scene or during an autopsy. Insects can be important biotaphonomic agents and their activity may result in artifacts that resemble antemortem injuries. Here, we describe postmortem injuries caused by the Neotropical wasp Agelaia fulvofasciata (Degeer, 1773) on domestic pig carcasses weighting 15 kg. The specimens showed extensive injuries to the lower lip, similar to lacerations, and some minor lesions on the snout and anus. In addition , we observed the same wasp species preying on larvae of Sarcophagidae (Peckia sp.). Besides causing postmortem injuries, the ability of this species to detect carcasses in the early and fresh decomposition stages should be noted. Thus, future applications aiming criminal, any biotaphonomic events caused by carrion insects need to be disclosed.

They claimed that intraspecific variation in the genus is meaningful, and proper consideration yields a conclusion different from that of Andena et al. Both their critique and reanalysis are vitiated by numerous errors, as is shown in the present paper.

O método adotado para os trabalhos de inventário da diversidade de artrópodes pela equipe do PPBio Semiárido Invertebrados foi baseado em excursões de coleta com a participação de todas as equipes. Este se mostrou eficiente no que se refere a amostragem, assim como, se estabeleceu uma parceria interinstitucional importante para o funcionamento da rede de pesquisa do Semiárido, meta do PPBio. O fruto deste trabalho pode ser observado nos 22 capítulos que tratam dos distintos táxons de artrópodes coletados.

Social wasps are an important ecological group, which has been utilized for biological control and as bioindicators of environmental quality. Few studies about the diversity of social wasps were accomplished in the Caatinga and there is no survey of social wasps in the state of Paraiba. This study used data collected from city of Sumé, through field research and analysis of previously deposited material from surveys realized by Brazilian Corporation of Agricultural Research (EMBRAPA). Two species of social wasps, Polistes simillimus and Mischocyttarus cearensis, were recorded for the first time in state of Paraiba.

Therefore the purpose of this work was to increase the knowledge of social wasp fauna at the Jaú National Park. A total of 494 specimens of Polistinae was collected with active search, malaise trap and light trap. Forty-nine species belonging to fourteen genera were recorded. The richest genera were Polybia (14 species), Agelaia (07), Mischocyttarus (05), Apoica (04), Brachygastra (04) and Protopolybia (04); the remaining genera were represented by less than two species. The Jaccard similarity coefficient showed a higher similarity of the Jaú National Park with Ducke Reserve (Manaus, Amazonas). Four species were collected for the first time in Amazonas state Agelaia flavipennis (Ducke), Polybia affinis Du Buysson, Protopolybia nitida (Ducke) and Protopolybia sedula (de Saussure), only in the Jaú National Park, showing the importance of this park for the social wasps preservation in the Amazon region. Fauna de Vespas Sociais (Hymenoptera: Vespidae: Polistinae) do Parque Nacional do Jaú, Amazonas, Brasil Resumo. Vespas sociais são elementos comuns na região Neotropical, embora até mesmo os dados elementares sobre este táxon na região amazônica ainda sejam parcialmente desconhecidos. Por isso objetivamos contribuir para o conhecimento sobre a fauna de vespas sociais que ocorrem no Parque Nacional do Jaú. Um total de 494 indivíduos de Polistinae foi coletado através de busca ativa, armadilha Malaise e armadilha luminosa. Quarenta e nove espécies de 14 gêneros foram registradas. Polybia (14 espécies), Agelaia (07), Mischocyttarus (05), Apoica (04), Brachygastra (04) e Protopolybia (04) são os gêneros com o maior número de espécies; os demais gêneros coletados foram representados por apenas uma ou duas espécies. De acordo com o coeficiente de similaridade de Jaccard, a composição de espécies de Parque Nacional do Jaú é semelhante a Reserva Ducke (Manaus, Amazonas). Agelaia flavipennis (Ducke), Polybia affinis Du Buysson, Protopolybia nitida (Ducke) e Protopolybia sedula (de Saussure) são considerados novos registros de ocorrência para o estado do Amazonas e foram coletados, até o momento, apenas no Parque Nacional do Jaú, demonstrando a importância deste parque para a preservação de vespas sociais na região amazônica.

This work presents similarities among bee species based on visited plants and also shows taxonomic diversity of bees for plant resource sets offered by species in a cerrado area (Pé-de-Gigante), one of the few conservation areas of cerrado in the São Paulo State, Brazil. A total of 737 specimens, belonging to 71 bee species, were collected visiting 52 plant species. Species clusters based on visited plants show that species of Epicharis, for example, are more similar among themselves than from species of other genera. In addition, bee assemblage showed a nested structure, indicating the presence of specialist species exploiting resources subsets used by generalist species under strong intra-specific and weak inter-specific competitions.

Synoeca septentrionalis was previously recorded only from Central America and northwestern South America. This findingextends its geographical distribution to Northeast and Southeast regions of Brazil, and represents the first record for Synoeca septentrionalis in the Brazilian Atlantic Rain forest, raising to three the number of Synoeca species known from Bahia State.

A single cladogram resulted from the analysis of 31 morphological characters and six nest characters, with relationships among the species as follows: ((C. fulvus + C. xanthura) + (C. weyrauchi + (C. nevermanni + (C. carinatus + C. zavattarii)))). The monophyly of the genus is confirmed and a new identification key is presented. Notes on the nest are given and the misidentification of C. carinatus is explained.
