ABSTRACT
ABSTRACT Scarabeoidea (Insecta: Coleoptera) present more than 2000 species recorded from all over Brazil. They have been scarcely recorded from caves, and truly troglobitic species are yet to be found in the country. In this study, we carried out a review of all existing scarab beetles deposited until 2017 in the Coleção de Invertebrados Subterrâneos de Lavras (ISLA), at the Universidade Federal de Lavras (UFLA) (Minas Gerais, Brazil), one of the most important collections of subterranean invertebrates in South America. Ninety-two individuals belonging to 52 species were recorded, distributed in six families (Cetoniidae, Hybosoridae, Melolonthidae, Passalidae, Scarabaeidae and Trogidae). Scarabaeidae was the most diverse of them, representing more than 50% of the total of species recorded. We found Scarabeoidea beetles in 51 of the ~ 1600 caves examined, distributed in nine Brazilian states: Alagoas, Bahia, Distrito Federal, Espírito Santo, Goiás, Minas Gerais, Pará, Piauí, and Tocantins. Our results provide evidence that Scarabaeoidea beetles are not frequent in Brazilian caves, and their records in this kind of environment are mostly accidental. Exceptions include Trogidae and Aphodiinae species, which may be associated with bat guano. Our study presents the first list of Scarabaeoidea species sampled in Brazilian caves.
ABSTRACT
ABSTRACT The taxonomic status and the geographic distribution of two species, Pelidnota gounellei (Ohaus, 1908) and P. ludovici Ohaus, 1905, is revised and the species are revalidated. A lectotype for Pelidnota tricolor Nonfried, 1894 is designated. The taxonomy of the species is briefly discussed, and a distribution map for the reviewed species is also provided. The distribution range of P. gounellei is expanded to the Minas Gerais state, Brazil.
ABSTRACT
ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

Illustrations and diagnostic characters are also presented, along with additional characters for the genus, and a new state record for Pernambuco is added. With this study, two species of immatures of Chlorota are now known and their diagnostic characters and differences are here discussed.
ABSTRACT
ABSTRACT The oil palm is an economically important crop cultivated in the North of Brazil. Damage caused by insects is one of the main causes of reduced productivity for the oil palm. Before this research, only the beetles of the family Curculionidae were considered to be oil palm pests in Brazil. However, for the first time, we report on the damage caused by a giant rhinoceros beetle to oil palm plantations in Pará, Brazil. The beetle was identified as Golofa claviger (Linnaeus, 1771), which has a single record in Brazil (Pará) but is widely distributed in South America. The species occurs in an unprecedentedly high abundance of local specimens. The attacks are concentrated on the central cluster of young palms. Feeding behavior is identified as the main cause of the damage as the beetles use their mouthparts to rip the plant tissues, causing wedge-shaped cuts on young fronds that have not yet unfurled. After an attack, the leaflets of the unfurled fronds are partially destroyed.

ABSTRACT
ABSTRACT Bothynus cribrarius (Fairmaire) was rediscovered after studying the MNRJ and FIOC collections. The male is described and illustrated for the first time. Accurate location data is presented after 130 years since its species description.
ABSTRACT
ABSTRACT Dynastinae is one of the most representative subfamilies of Melolonthidae (Scarabaeoidea) and has considerable ecological importance due mainly to interactions with plants of the families Araceae and Annonaceae. This relationship has led to the evolution of nocturnal activity patterns, which are influenced by environmental conditions. In the present study, abiotic factors were investigated to comprehend the influence on the flight patterns and identify the sex ratio of beetles from this subfamily. A study was conducted at Campo de Instrução Marechal Newton Cavalcanti in northeastern Brazil between December 2010 and November 2011. Thirteen species of Dynastinae were identified, most of which were from the genus Cyclocephala. Abundance and richness were greater in the dry season. Six species exhibited peak flight activity at specific periods of the night. More females than males were recorded for Cyclocephala distincta and C. paraguayensis. The present findings suggest that rainfall reduces the flight activity of these beetles and different time schedules may be related to mating behavior, foraging behavior and the avoidance of interspecific resource competition.
ABSTRACT
ABSTRACT A list of the Coleoptera of importance from Brazil, based on published records was compiled. The checklist contains 345 species of 16 families allocated to 16 states of the country. In addition, three species of two families are registered for the first time. The fauna of Coleoptera of forensic importance is still not entirely known and future collection efforts and taxonomic reviews could increase the number of known species considerably in the near future.
ABSTRACT
Histeridae is a group of beetles with diverse morphology known as generalist predators and which occurs in a wide variety of habitats. The objective of this paper was to present the first list of Histeridae from the Campos Gerais region (Parques Estaduais de Vila Velha, do Cerrado, e do Cânion Guartelá) and provide information about species from protected areas in the state of Paraná. Also were provided appropriate collecting methods for the group. The Histeridae from Campos Gerais are represented by 29 species belonging to eight genera: Haeteriinae sp. (1 sp.), Coelister Bickhardt, 1917 (1 sp.), Epierus Erichson, 1834 (1 sp.), Euspilotus Lewis, 1907 (6 spp.), Hister Linnaeus, 1758 (2 spp.), Omalodes Dejean, 1833 (3 spp.), Operclipygus Marseul, 1870 (6 spp.) and Phelister Marseul, 1854 (9 spp.). Two genera (Coelister and Epierus) and four species (Coelister sp., Phelister brevistrius Marseul, 1854, Phelister panamensis LeConte, 1859 and Phelister pumilus (Erichson, 1834)) were recorded for the first time for the state of Paraná. Five genera (Coelister, Epierus, Euspilotus, Hister and Phelister) and five species (Coelister sp., Omalodes laceratus Marseul, 1853, Phelister brevistrius, Phelister panamensis LeConte, 1859 and Phelister pumilus (Erichson, 1834)) were recorded for the first time for Campos Gerais. The fauna of Histeridae is diverse when compared with surveys conducted in other floristic conditions. However, the majority of species do not demonstrate a selection for open grass field areas. Considering the habitats loss of Campos Gerais it is important to increase the faunistic surveys with appropriate methodology and regional lists of Coleoptera in order to know the biodiversity.
Histeridae é um grupo de besouros com morfologia diversificada, conhecidos como predadores generalistas e que ocorrem em uma ampla variedade de habitats. O objetivo deste trabalho foi apresentar uma primeira listagem dos táxons de Histeridae ocorrentes na região dos Campos Gerais (Parques Estaduais de Vila Velha, do Cerrado, e do Cânion Guartelá) e fornecer informações sobre as espécies das Unidades de Conservação do Estado do Paraná. Também foram apresentados os métodos apropriados para coleta do grupo. Os Histeridae dos Campos Gerais estão, até o momento, representados por 29 espécies de oito gêneros: Haeteriinae sp. (1 sp.), Coelister Bickhardt, 1917 (1 sp.), Epierus Erichson, 1834 (1 sp.), Euspilotus Lewis, 1907 (6 spp.), Hister Linnaeus, 1758 (2 spp.), Omalodes Dejean, 1833 (3 spp.), Operclipygus Marseul, 1870 (6 spp.) e Phelister Marseul, 1854 (9 spp.). Dois gêneros (Coelister e Epierus) e quatro espécies (Coelister sp., Phelister brevistrius Marseul, 1854, Phelister panamensis LeConte, 1859 e Phelister pumilus (Erichson, 1834)) foram registrados pela primeira vez para o Estado do Paraná. Cinco gêneros (Coelister, Epierus, Euspilotus, Hister e Phelister) e cinco espécies (Coelister sp., Omalodes laceratus Marseul, 1853, Phelister brevistrius, Phelister panamensis LeConte, 1859 e Phelister pumilus (Erichson, 1834)) foram registrados pela primeira vez para os Campos Gerais. A fauna de Histeridae se mostrou diversa quando comparada a levantamentos em outras formações vegetacionais. Entretanto, a maioria das espécies não demonstra uma seleção de hábitat para áreas abertas. Considerando a perda de habitat ocorrida nos Campos Gerais, salienta-se a importância dos levantamentos faunísticos através de métodos apropriados e listagens regionais de Coleoptera para o conhecimento da biodiversidade.
ABSTRACT
The açaí palm (Euterpe oleracea) is an East Amazon palm found most frequently in the Amazon River estuary. Riverside dwellers in different regions of the state of Amapá have recently been observing a species of coleopteran attacking the inflorescences of açai palms. With a view to identifying a species of coleopteran attacking inflorescences of E. oleracea in the Brazilian state of Amapá, insects were collected in the regions of Abacate da Pedreira (two individuals) and Ariri (six) in the city of Macapá. Five individuals were also collected in Mazagão. The insects were collected from açai palm inflorescences using entomological nets, then preserved and submitted for identification. They were identified as Macraspis pseudochrysis Landin, 1956 (Coleoptera: Scarabaeidae: Rutelinae). This is the first occurrence of M. pseudochrysis in E. oleracea in the Neotropics.
O açaizeiro [Euterpe oleracea] é uma palmeira da Amazônia Oriental encontrada com mais freqüência no estuário do Rio Amazonas. Recentemente, ribeirinhos em diferentes regiões do estado do Amapá observaram uma espécie de coleóptero que ataca as inflorescências de açaízeiros. Com o objetivo de identificar exemplares de Coleoptera em inflorescências de E. oleracea no estado do Amapá, Brasil, foram coletados 13 indivíduos nas localidades de Abacate da Pedreira (dois exemplares), Ariri (seis)(ambas em Macapá) e no município de Mazagão (cinco), entre outubro de 2010 e fevereiro de 2011. Os coleópteros foram coletados diretamente nas inflorescências de açaizeiros com auxílio de rede entomológica, conservados e enviados para identificação. Todos os indivíduos pertencem à espécie Macraspis pseudochrysis Landin, 1956 (Coleoptera: Scarabaeidae: Rutelinae). Este é o primeiro registro de ocorrência de M. pseudochrysis em E. oleracea na região neotropical.
