摘　　要：Climatic conditions affect the richness of ants resulting in number variation throughout the year. The ants present in the Neotropical system <em>Acacia-Pseudomyrmex</em> have been previously studied considering only one sampling season. In contrast, in this study we analyze the richness in two ant-acacia systems during the rainy and dry seasons. The study was carried out on a plot located in the state of Oaxaca, Mexico where 14 ant species, 3 mutualistic and 11 non-mutualistic were found, of which 2 represent new records for the state. Ant species number differed between ant-acacia species and between seasons. The highest richness was recorded in <em>Acacia hindsii</em> in both rainy and dry seasons, corresponding with a low-reward host. During the dry season, <em>A. hindsii </em>represents a highly valuable resource. This study shows that the neotropical system is much more dynamic than it has been previously considered and offers a valuable opportunity for subsequent ecological studies for a better understanding of this complex system.Climatic conditions affect the richness of ants resulting in number variation throughout the year.
