英文摘要： Boysidia Ancey, 1881 is a small group in Chondrininae and distributes in South and Southeast Asia. A total of 24 species were recorded in south Qinling Mountains, China. Among of these species, one was identified as a new record. Descriptions of this new species and other 8 species of Boysidia ( Bensonenella) were given in the text. The type specimens of the new species were kept in Institute of Zoology, Chinese Academy of Sciences, and the Department of Cell Biology and Medical Genetics, Kunming Medical University.
