Abstract The Brazilian Atlantic Forest is considered one of the most threatened tropical forests in the world due to the extensive environmental impact it has endured throughout history. Only 12.4% of its original vegetation is estimated to remain. Even though reduced and highly fragmented, it houses enormous biodiversity, and its preservation is paramount to the maintenance of the country’s fauna, flora, funga and microbiota. One of the most efficient measures adopted by public agencies aimed at protecting biodiversity has been the creation of conservation units. To evaluate the preservation state of protected areas, several environmental studies have been performed; species inventories are one among them. Ants are excellent bioindicators, for they are not only sensitive to environmental changes, but they also have a history of being used in impact assessment (i.e., fragmentation). In this study we assessed the ant communities inhabiting the leaf litter in areas with different regeneration states at the RPPN Botujuru - Serra do Itapety (Mogi das Cruzes, São Paulo - Brazil). Mini-Winkler traps were used in the ant survey, and diversity analyses were performed. In total, we recorded 86 species of ants, with a highlight to Camponotus cillae Forel, 1912, a species that remained unrecorded for the state of São Paulo for over 100 years, and a possible new species of Octostruma Forel, 1912. Overall, the species found show that the areas are in the process of natural regeneration. Our data on RPPN Botujuru is unprecedented, and our species list has the potential of being used as an effective monitoring tool for this conservation unit.

Abstract The state of Maranhão, located in northeastern Brazil, comprises three biomes: Amazonian, Caatinga, and the Cerrado. To date, 99 ant species have been recorded in the literature from the state. In the present work, we provide for the first time a profile of the ant fauna in the state based on data from the historical literature and Brazilian institutional collections. The updated records on ant diversity for the state of Maranhão revealed a total of 279 species, belonging to 71 genera and 10 subfamilies. In total, 180 species are recorded for the first time in the state, of which four species recorded for the first time in Brazil. In summary, apart from documenting the ant fauna of the region, these results provide a basis for further studies and may contribute to future conservation efforts for the biomes present in this complex landscape.

Abstract The state of Mato Grosso is the 3rd largest Brazilian state, is covered with three major Brazilian biomes, including the Pantanal, Cerrado, and Amazonia. To date, 449 ant species are recorded in literature for the state. In the present work, we documented the ants sampled along a fragmented landscape, in the municipality of Juara, in the Cerrado-Amazon transition zone in the state of Mato Grosso, Brazil. The ant species were captured with Pitfall traps installed in 20 trails with 10 traps in each (totaling 200). Our results show 151 species, belonging to 43 genera and eight subfamilies, of which 28 species were recorded for the first time in the state and five species recorded for the first time in Brazil. Most genera collected were Pheidole Westwood, 1839 (45 species) followed by Crematogaster Lund, 1831 (11 species). By highlighting species recorded for the first time in state of Mato Grosso and Brazil, we hope to encourage new discoveries and increase the general knowledge of the ant fauna of different biomes in the region.

RESUMO Este catálogo inclui os tipos de formigas de três subfamílias (Dolichoderinae, Formicinae and Martialinae) depositados na Coleção de Formicidae do Laboratório de Hymenoptera, Museu de Zoologia da Universidade de São Paulo (MZSP), Brasil. Apresentamos a informação de rótulos e sobre a condição morfológica dos espécimes, bem como as eventuais mudanças nomenclaturais e novos status taxonômicos seguindo as recomendações do Código Internacional de Nomenclatura Zoológica. Listamos os tipos de 101 espécies de formigas (sendo 96 atualmente válidas); oito espécies listadas são representadas somente por holótipos, 27 por parátipos, sete por holótipos e parátipos, 56 apenas por síntipos, duas espécies por paralectótipos e uma espécie pelo lectótipo e paralectótipos. O presente trabalho completa a série de publicações sobre os tipos de formigas da coleção do MZSP, que inclui 4.741 espécimens tipo de 892 espécies nomenclaturalmente válidas.

ABSTRACT This catalogue lists types of three ant subfamilies (Dolichoderinae, Formicinae and Martialinae) housed in the Formicidae Collection of the Hymenoptera Laboratory, Museu de Zoologia da Universidade de São Paulo (MZSP), Brazil. It provides label information, morphological condition of specimens, nomenclatural changes, and type status, following recommendations of the International Code of Zoological Nomenclature (ICZN). Here we present information on types of 101 nominal species, of which 96 are still valid. Eight species are only represented by holotypes, 27 species only by paratypes, seven by holotypes and paratypes, 56 species by syntypes, two species by paralectotypes and one species by a lectotype and paralectotypes. With this issue we complete the publication of information regarding all MZSP ant types, summing 4,741 specimens of 892 nomenclaturally valid species.
