A new species of fossil winged fruits of Palaeocarya (Juglandaceae) is recognized from the Oligocene Ningming Formation in Guangxi, South China. The fruits of Palaeocarya huashanensis sp. nov. consist of a trilobate wing with an oblong median lobe, pinnate and cucamptodromous lobe venation, a hispid nutlet, and a very short pedicel. This new species, along with other four species reported previously from the same locality, represents the Oligocene Palaeocarya occurrence in the lowest latitude and provides additional evidence of diversity of Juglandaceae in the Paleogene in South China, and new data for the investigation of the origin and evolution of the tribe Engelhardieae.
