The specimens were collected from Shule County of Kashgar, Xinjiang （39°14%I, 76° 22E; elev. 1248 m）. All the specimens are kept in Institute of Zoology, Shaanxi Normal University. A key based on worker caste to known species of Cardiocondyla from China is provided.展开更多

The ants present in the Neotropical system Acacia-Pseudomyrmex 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 Acacia hindsii in both rainy and dry seasons, corresponding with a low-reward host. During the dry season, A. hindsii 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.展开更多
