摘　　要：Two chiton specimens were collected from sedimentary habitat by China＇s manned Jiaolong submersible diving to a depth of 6 754 m in the north of the Yap Trench. This is a new locality record for chiton. Both morphological and molecular data support that the two specimens are the same species belonging to the genus Leptochiton. Morphologically, this species strongly resembles L. vanbellei and L. deforgesi. Phylogenetically, it has a close evolutionary relationship with L. vanbellei, L. deforgesi and L. boucheti. This is the third deepest record for deepsea chitons so far.Two chiton specimens were collected from sedimentary habitat by China＇s manned Jiaolong submersible diving to a depth of 6 754 m in the north of the Yap Trench.
