Acknowledgments:

We thank the staff of the Kon Chu Rang Nature Reserve for their support during our fieldwork. The work was performed within the framework of the Joint Russian–Vietnamese Biological Expedition, financially supported by the Russian Academy of Sciences. The collection of materials was conducted under the Agreement on the scientific cooperation between Kon Chu Rang Nature Reserve and the Joint Russian–Vietnamese Tropical Research and Technological Center.

Annotation:

One new species of Symbioribates (Oribatida, Symbioribatidae) is described, based on adults collected from tree branches in the Kon Chu Rang Nature Reserve, central Vietnam. Symbioribates sacculus sp. n. is characterized by the presence of saccules and a heavy granulate cerotegument on the notogaster.
