Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant species in the Atlantic Forest of South America. The ATLANTIC ANTS data set, which is part of the ATLANTIC SERIES data papers, is a compilation of ant records from collections (18,713 records), unpublished data (29,651 records), and published sources (106,910 records; 1,059 references), including papers, theses, dissertations, and book chapters published from 1886 to 2020. In total, the data set contains 153,818 ant records from 7,636 study locations in the Atlantic Forest, representing 10 subfamilies, 99 genera, 1,114 ant species identified with updated taxonomic certainty, and 2,235 morphospecies codes. Our data set reflects the heterogeneity in ant records, which include ants sampled at the beginning of the taxonomic history of myrmecology (the 19th and 20th centuries) and more recent ant surveys designed to address specific questions in ecology and biology. The data set can be used by researchers to develop strategies to deal with different macroecological and region‐wide questions, focusing on assemblages, species occurrences, and distribution patterns. Furthermore, the data can be used to assess the consequences of changes in land use in the Atlantic Forest on different ecological processes. No copyright restrictions apply to the use of this data set, but we request that authors cite this data paper when using these data in publications or teaching events.
Eumeninae is the most diverse group of Vespidae, with 3,579 species in 210 currently recognized genera in the world (Brothers & Finnamore 1993; West-Eberhard et al. 1995; Sarmiento & Carpenter 2006; Pickett & Carpenter 2010). Brazil harbors a significant richness of these wasps, with 277 species and 31 genera described. However the biology of these species in general is poorly known (Carpenter & Marques 2001; Pickett & Carpenter 2010; Hermes et al. 2013). Adults of Eumeninae feed on nectar while the larvae are predators. Females build the nest that can be dug, made with mud or even occupying pre-existing cavities, and hunt caterpillars to provide food for the larvae (Evans 1956; Krombein 1979; Carpenter & Marques 2001; Hunt et al. 2003). Among the natural enemies of Eumeninae there are birds, ants (Ecitoninae), bats and parasitoids (West-Eberhard et al. 1995). Insect parasitoids develop feeding on immature stages of other Arthropoda, usually killing the host (Doutt 1973; Godfray 1994). Hymenoptera is the group with most representatives among parasitoids, being responsible for 75% of the species, but this behavior also appears in other orders as Diptera, Coleoptera, Lepidoptera, Trichoptera, Neuroptera and Strepsiptera (Krombein 1967; Askew 1971; Quicke 1997). The records presented here were made in two localities from Mato Grosso do Sul state, mid-western Brazil; both located in the Chacoan sub-region, Cerrado province (Morrone 2014). We collected four nests of Eumeninae, built with mud and set on shrubs, in the municipality of Dourados (22°11'41''S; 54°55'45''W); and one mud nest in Parque Nacional da Serra da Bodoquena (20°44'24''S; 56°44'13''W). The nests were brought to the Universidade Federal da Grande Dourados, and kept at approximately 26°C. Voucher specimens are deposited at the Museu de Biodiversidade (MuBio
ABSTRACT. Spheciformes Wasps (Hymenoptera, Apoidea) from Mato Grosso do Sul, Brazil. Here we present a species list of spheciformes wasps of the families Ampulicidae, Sphecidae and Crabronidae, registered in west and southwest of the Mato Grosso do Sul state, Brazil. The surveys were conducted in 22 sampling points, with emphasis on Serra da Bodoquena region, covering the biomes: Cerrado, Atlantic Forest and Chaco. We recorded 506 individuals distributed in 47 genera and 109 species. Trypoxylon Latreille was the most diverse genus with 155 individuals collected and 12 morphospecies, being the only genus sampled in all methodologies. Eremnophila binodis (Fabricius, 1798) was the most abundant species recorded from these wasps with 35 individuals collected. This list adds 83 new records to this wasp's distribution in the state, expanding to 139 species of wasps spheciformes known to the state.KEYWORDS. Crabronidae, Neotropical Region, solitary wasps, Sphecidae, Biota-MS Program.RESUMO. Apresentamos aqui uma lista de espécies de vespas esfeciformes das famílias Ampulicidae, Sphecidae e Crabronidae registradas para o oeste e sudoeste do estado de Mato Grosso do Sul em inventários recentes realizados em 22 pontos amostrais, com principal ênfase na Serra da Bodoquena, contemplando os principais biomas do estado como o Cerrado, a Mata Atlântica e o Chaco Brasileiro. Foram registrados 506 indivíduos distribuídos em 109 espécies e 47 gêneros. Trypoxylon Latreille foi o gênero mais diverso com 155 indivíduos coletados e 12 espécies, sendo o único gênero amostrado em todas as metodologias. Eremnophila binodis (Fabricius, 1798) foi a espécie mais abundante registrada dentre os esfeciformes, com 35 indivíduos coletados. Esta lista acrescenta 83 novos registros de distribuição de espécies dessas vespas no estado, ampliando para 139 espécies de vespas esfeciformes conhecidas para o estado.
Astatid wasps are referred to in literature as specialized predators of hemipterans. We present an unusual prey record for the genus Astata in a Cerrado area (Savannah), at Chapada dos Veadeiros National Park, Goiás State, Brazil. We collected one specimen of Astata lugens Taschenberg carrying an immature cricket (Gryllidae) as prey.
