Abstract: The present paper deals with a new antiarch Heteroyunnanolepis quiingensis gen. et sp. nov., collected from the Lower Devonian of Cuifengshan, Qujing, Yunnan in 1990. Only external or internal molds are preserved and available for study, the new genus is attributed to Yunnanolepidae mainly in the light of general similarity to the previously described forms of the family, in particular, axial joint without brachial process, pattern of skull-roof.

摘要： 本文记述了云南鱼类一新属新种—曲靖异云南鱼(Heteroyunnanolepis qujingensis gen. et sp, nov.)。它与已知云南鱼类的主要区别在于:1)眶下沟通过后缘片;2)不具眶前凹槽而具眶前凹。基于对新属详细的描述和比较，对胴甲类中“后缘片”和“前鳃盖沟”的同源关系，眶前凹槽和眶前凹相互关系做了尝试性的探讨。
