Gazing into the Colombian Amazon ant diversity: Advances and perspectives in a war-torn country

Poster
Despite a large number of expeditions carried out in Colombia, in-depth analyses of its diversity and species richness are still incipient. Restricted and onerous access to most of its territory, the internal conflict of the country, and lack of research investment, significantly hamper any further studies. Nevertheless, recent field trips and routine curatorial activities in major entomological collections are helping to increase the knowledge of Colombian ant fauna. The present study seeks to contribute to the know species richness, biogeographical distribution, and ecological knowledge of the uncharted Colombian Amazon myrmeco-fauna. Through the implementation of different field-sampling methodologies (i.e. manual, Winkler, pitfall, monoliths, and sweeping), and curatorial work from different amazon biodiversity projects, including the Colombia Bio Andaki/Apaporis/Chiribiquete Expedition 2018, and the Conservation and sustainable use of the biological, socioeconomic, and cultural diversity of the Colombian Amazon SINCHI Institute Project, a total of 17074 specimens belonging to 315 species, 78 genera, and ten subfamilies have been recorded from all Colombian Amazon states. Numerous new species and records were identified, while new occurrence data lay the foundation for further taxonomic and ecological studies, mainly from subterranean and ground-dwelling ant species. Results here serve as base-line information to strengthen entomological studies in Colombia. Nevertheless, maintaining and improving inter-institutional cooperation is required to gather detailed biological knowledge at a local and regional scale, mainly in unexplored amazon South-eastern and central localities.
