醯落 / Xiluo (Southern Xiongnu)
Hanji 939 introduces 醯落 / Xiluo as a right-division 南匈奴 rebel actor. After the Han court orders Southern Xiongnu cavalry to support 刘虞 against 张纯, Xiluo helps lead the backlash against repeated requisition.
The source says Xiluo joins with the 屠各胡, gathers a large rebel force, kills 羌渠, and opens the succession of 于扶罗. His page is source-scoped as an internal-revolt node rather than a full biography.
