The genus name translates as "Yi People's shield", deriving from the Chinese name Yímín (simplified Chinese: 彝民; traditional Chinese: 彞民; lit. 'Yi People', an ethnic group in China, Vietnam, and Thailand) and the Greek word aspis ("a type of round shield"). The specific name is from Chinese shénme (simplified Chinese: 什么; traditional Chinese: 什麼; lit. 'what'), as in "what is it?" reference to the peculiar anatomy of this prehistoric fish.[1]
Yiminaspis belongs to the family Wuttagoonaspidae, and is closely related to Wuttagoonaspis. It is one of the more basal members of the order Arthrodira, as shown in the cladogram below: [2]
