Abstract: The actinopterygian specimens described here were collected from Weixin, Yunnan by the Regional Geological Surveying Brigade of Guizhou Province. It was alleged that all the 25 specimens were discovered from "Xiangxi Formation" (Lower Jurassic). Four of them are assigned to a new genus and species, Weixiniscus microlepis, of the Palaeoniscidae. The others are referred to a new genus and species, Zaxilepis qinglongensis, of the Archaeomaenidae. Previously archaeomaenids were known only from Australia and Antarctica of Gondwanaland, this new discovery is of significance in the understanding of the distribution of Mesozoic freshwater fishes.

摘要: 文记述了云南威信“香溪组”古鳕科(Palaeoniscidae)一新属、新种——小鳞威信鳕(Weixiniscus microlepis gen. et sp. nov.)和古腊鱼科(Archaeomaenidae)一新属、新种——青龙扎西鱼(Zaxilepis qinglongensis gen. et sp. nov.)。根据鱼化石性质,将含鱼化石地层时代定为早侏罗世。并对古腊鱼科初见于北大陆作了探讨。
