| 中文摘要: |
| 蛟龙号载人潜水器在位于雅普海沟北部6 745 m深处的底栖沉积环境中采集到两只石鳖样本，这是石鳖物种分布于此的新记录。形态学和DNA分子标记均支持两只石鳖为鳞侧石鳖属（Leptochiton）同一物种。该种在形态上与L.vanbellei和L.deforgesi接近；在系统发生方面，与L.vanbellei，L.deforgesi和L.boucheti的亲缘关系密切。这是截至目前世界石鳖分布报道的第三深度记录。 |
| 英文摘要: |
| 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 deep-sea chitons so far. |
