Abstract: The François’s langur (Trachypithecus francoisi) is a nationally protected animal in China. Individual identification of the François’s langurs is essential for monitoring, research, and conservation management. Mayanghe National Nature Reserve in Guizhou Province is the largest habitat for wild populations of the François’s langur. In this study, three groups of wild François’s langurs within the experimental area of Mayanghe Reserve were selected. The instantaneous scan sampling method was used to observe the gibbon groups, and digital cameras were used to photograph the ventral groin patches of 16 adult and sub-adult females. By comparing the results, we found that there were individual differences in the patterns of ventral groin patches among François’s langurs, suggesting that these patterns can be used as a method for identifying individuals. This study provides new insights and research methods for individual identification of François’s langurs and contributes to the fundamental data for studying their behavior in the wild. Furthermore, it offers a scientific basis for the conservation and management of François’s langurs.
