Resumen:
The family Nemesiidae is the second most diverse family of Mygalomorphae spiders. Acanthogonatus centralis (Nemesiidae) is commonly found in hilly areas of central Argentina. These spiders are considered generalists due to their basal position in the phylogeny, but little is known about the trophic ecology of the species. Therefore, the objectives of this study were to study some ofthe species? predatory traits, such as feeding frequency and prey acceptance, and to assess its natural diet. Inaddition, two parameters - attack latency and consumption time - were measured for each accepted prey. Wefound that A. centralis feeds every two days and accepts almost all prey offered. The most accepted prey itemswere beetle larvae and termites. In fact, termites were attacked faster than any other prey, suggesting they are asuitable prey for these spiders. In regard to the species? natural diet, we found remains of seven prey items, antsand beetles being the most frequent. In this study, we found that Acanthogonatus centralis is polyphagous sinceit accepts different kinds of prey.
