The pre-congress mini courses of the VII Latin American Congress of Arachnology are offered by researchers with recognized experience, who have decided voluntarily and without financial remuneration to provide these short training sessions, for the personal satisfaction of contributing to the formation of the arachnological community, especially undergraduate students. The money raised by these activities will constitute an economic input for the realization of the VII CLA - Colombia 2024. This course aims to give a quick and complete introduction to Neotropical jumping spiders as well as the systematic tools and methodologies used for their taxonomic determination.
