ABSTRACT
Biological collections are important repositories of biodiversity, as they include various types of data potentially useful to different areas of science and can contribute to the establishment of biodiversity conservation policies. For a long time, scientific collections were considered only as physical databases; in this context Harold G. Fowler (19502018) built an ant collection at the Universidade Estadual Paulista, campus Rio Claro (So Paulo state, Brazil), over the course of a 34-year career, comprising around 20,000 ant specimens. Most specimens came from the Brazilian Atlantic Forest, but many others came from distinct locations in Brazil and abroad. After his death, the collection was left without the necessary curatorial care for a period of time, which required a project to be conceived for its recovery and conservation, with the goal of incorporating it to the Zoology Museum of the University of So Paulo (MZSP). In addition to applying modern technical curation protocols, other activities such as checking, material identification and digitization of the information contained on the sample labels were carried out, forming an accurate database. This process enabled the identification of new distribution records and the discovery of possible undescribed species and unpublished natural history data. After validating this information, we counted 524 valid species and 201 morphospecies belonging to 105 genera and 10 subfamilies. In addition, we integrated technical curation activities with scientific outreach to draw the general publics attention to the importance of biological collections, thus fostering interest in science, biodiversity and nature conservation. Our work highlights the importance of preserving the areas sampled by Fowlers research group. The preservation of vouchers using curatorial practices reinforces the role of scientific collections as important tools for the study, understanding and preservation of biodiversity.

The ant genus Basiceros is an exclusively Neotropical group known for its cryptic habits. Based on a recent molecular phylogenetic framework, a comprehensive revisionary study of the genus is presented. Nine species are recognized, two of which are described as new (Basiceros browni sp. nov. and Basiceros tumucumaquensis sp. nov.). Basiceros redux (Donisthorpe 1939) is transferred to the genus Octostruma (O. reducta comb. nov.). As part of this revisionary work, taxonomic keys and images to all species and castes are provided. Castes and sexes (including larvae, males, and intercastes) are described for the first time for several Basiceros species. New records considerably expand the distributional range for most species. Natural history data and comments on character plasticity and convergence are also included.

The state of Par in northern Brazil is located entirely within the Amazon Basin and harbors a great diversity of landscape and vegetation types that support high levels of biodiversity. Here, we provide a comprehensive inventory of ant species and their distribution in Par. This regional list is based on an extensive review of species records from published and unpublished sources covering a period of 134 years (18862020) and includes the five most representative ant collections in Brazil. In total, we documented 12 subfamilies, 90 genera and 753 ant species, including 97 species recorded for the first time in Par and 12 species newly reported in Brazil. Sampling effort across the state is highly uneven, and most records may be associated with research areas near the state capital, mining areas, hydroelectric dams, and research field stations run by the state or universities. In addition, our results suggest a strong bias in ant collection in Par in terms of proximity of sampled sites to access routes, such as roads and rivers. We also found that species records were highly unevenly distributed based on areas of endemism within the Amazon, vegetation type, and protected areas within the state. Ant surveys are still lacking from most protected areas of Par, and further sampling is urgently needed in view of the current trend of expansion of major infrastructure projects and natural resource harvesting within protected areas of Par. Our database represents an extremely valuable and rich source of information for further studies on ant biodiversity and conservation in the Amazon Basin.
