Forest fragments associated with agricultural areas are beneficial for maintaining species that act as natural biological controls. Lacewings are an example of organisms that contribute to this control, however, there is little information on the sampling methodology for this taxon, as well as its occurrence in olive cultivation, Olea europaea L. (Lamiales: Oleaceae). Therefore, the aim of this study was to report the richness of lacewings (Neuroptera: Chrysopidae) collected with attractant traps in an olive orchard, associated with fragments of mixed Atlantic Forest. The traps were baited with passion fruit juice at a rate of 200 mL per bottle. The traps were installed at Sítio Carpe Diem, in the Serra da Mantiqueira, municipality of Cambuí, southern Minas Gerais (-22.625000 and -46.148333) from September 2023 to January 2024. As a result, a total of 109 lacewing specimens from one subfamily, two tribes, six genera and 14 species were collected. The occurrence of this taxon in the area may reflect the biome in which the property is located, the high temperature and the fragment of native forest. The data obtained in this study suggests that the use of passion fruit bait is advantageous for sampling lacewings, as well as highlighting the importance of agroecological practices for the permanence of natural enemies in cultivated areas.

Boreofairchildia Wagner & Stuckenberg, 2016 (Diptera: Psychodidae) currently includes fourteen acknowledged species. This genus is mainly found in the Neotropical region, although one species has been described from the Nearctic area. Two species are known Brazil, both from the state of Espirito Santo. In this paper, a new species from the Atlantic Forest of Espirito Santo is described, increasing the total number of Brazilian species to three and the overall species count in the genus to fifteen.

Solitary wasp nests (Sphecidae) are often occupied by other arthropods when abandoned. However, occupation by ants such as Cephalotes Latreille, 1802 is still uncertain. Species of Cephalotes are arboreal and occupy pre-existing cavities, commonly tree hollows. In this respect, the objective of this study is to report the first record of the ant Cephalotes pusillus (Klug, 1824) (Hymenoptera: Formicidae) nesting in a Sphecidae nest in areas cultivated with coffee, Coffea arabica L. The nest was collected on july 5, 2024, in a coffee plantation area in the municipality of Inconfidentes, Minas Gerais, Brazil. This area is associated with a fragment of Atlantic Forest. In the nest of Sceliphron sp. (Hymenoptera: Sphecidae), 64 pupae, 94 adults and four queens of the ant were counted. The successful occupation by the ant may have occurred due to different factors, such as the size and resistance of the nest, the size of the entrance and the multiple cells that are formed inside the nest, which allowed the use of this nest as an incubation site for the ant's larvae. This is the first record of C. pusillus nesting in a Sphecidae nest, but this species is a generalist in terms of the cavities it uses, requiring further observations to confirm the frequency of this behavior.

Cryptolestes obesus Thomas, 2002 (Coleoptera: Laemophloeidae) was described based on a single female specimen collected in Rondônia state, Brazil. As previously hypothesized, the robust body shape and the presence of complete secondary sublateral lines on the pronotum are diagnostic for C. obesus and fundamental traits for male association. Here we associate and describe the conspecific male, with a new record of this species for Santa Catarina state, Brazil. The habitus, antennal scape, and genitalia of the male are illustrated.

This study was conducted in an urban fragment of Cerrado (savannah formation) in the municipality of Campo Grande, Mato Grosso do Sul (MS), Brazil. McPhail traps, with sugarcane extract, were used along one year with the goals to sampling ulidiids flies. As results were presented new occurrences for four genera and seven species of uliidids for MS. Besides sampled four species belongs from three genera previous known from MS. The fauna of uliidids from MS increasing in 140% and 100% the number of the species and genera, respectively. Actually, the fauna of ulidiids from MS is represented by 12 species into eight genera.

The Gregório Bondar Entomological Collection (CEGB) of the Cocoa Research Center (CEPEC) has its origins in the 1930s with Dr. Gregório Bondar's insect collection that he constituted in the state of Bahia, Brazil. Bondar, a Russian-Brazilian entomologist, significantly contributed to Brazilian entomology and agriculture, and his extensive collection was in great part donated to the American Museum of Natural History. A smaller portion remained in Brazil and was eventually transferred to CEPEC in the 1960s. The collection, originally known as "Entomoteca Gregório Bondar", has grown to over 30,000 specimens by the 1980s. It holds valuable historical data that supports biodiversity monitoring and ecological research. The CEGB's Lepidoptera section features specimens collected from 1936 to 2024, mostly from the Atlantic Forest biome. This article aims to contribute to the knowledge of the distribution of butterflies in the Atlantic Forest, primarily from southern Bahia, by providing data on the specimens deposited in the CEGB at CEPEC in Ilhéus, Bahia, Brazil. A total of 531 specimens in 249 species of butterflies distributed within six families were recorded: 282 Nymphalidae (109 spp.), 107 Hesperiidae (63 spp.), 60 Riodinidae (31 spp.), 46 Lycaenidae (30 spp.), 33 Pieridae (14 spp.), and three Papilionidae (2 spp.). Specimens were collected from 11 localities in the Atlantic Forest biome. The CEGB provides data on butterfly distribution, including new records for the state of Bahia and the Atlantic Forest, highlighting its significance for research and conservation efforts.

The knowledge of arachnofauna from Tocantins, Brazil, is still incipient. The present communication expands the known geographical distribution of Loxosceles amazonica Gertsch, 1967 (Arachnida: Araneae: Sicariidae) in Brazilian Cerrado. The brown spider specimens were sampled in Dianópolis municipality and Cristalândia municipality both in Tocantins State, Brazil, between 2022 and 2024. Also, we describe a new variation of the epigynum of L. amazonica. Mapping the distribution of Loxosceles Heineken & Lowe, 1832 species in Brazil is crucial for public health, aiding in prevention and timely treatment of loxoscelism caused by brown spider bites.
