Hypodermosis is a disease caused by the infection of Hypodermatinae (Diptera, Oestridae) larvae. It seriously impact the development of agriculture, stock-breeding and public health. In this study we used morphological and molecular methods to identify the torsalo species infecting Plateau Zokor (Eospalax baileyi) in Luqu county, Gannan Tibetan Autonomous Prefecture, Gansu and to provide correct taxonomy for prevention, diagnosis and control of Hypodermosis. The result showed that the morphological characters of the third instar larvae were similar to the third instar larvae of Oestromyia leporina (Table 1). The difference of the partial COI gene sequences between the third instar larvae of studied torsalo and O. leporina was the smallest when compared with other three species of torsalo, with an average difference of 0.63% (Table 2). Based on phylogenetic analysis, the genetic distance between third instar larvae of studied torsalo and O. leporina was the shortest (Fig. 4). Therefore, it was determined that the torsalo infecting plateau zokor in Luqu county of Gannan Tibetan Autonomous Prefecture was O. leporina.
