N2 - In Chiapas, southern Mexico, there are Miocene amber deposits containing high diversity of biological inclusions of plants, fungi, crustaceans, and vertebrates. Here I describe a new species of Podopterus (Polygonaceae), P. mijangosae n. sp. based on well-preserved fruit fossils collected from the Los Pocitos mine, Chiapas. The fruit specimens are characterized by obovate shape, emarginate apex, cuneate base with three thin wings, and the endocarp being pubescent or tomentose. The wings are thin and translucent with entire to undulate margin, pubescent hairs, and fine fusiform-reticulate venation. This new record of Podopterus represents the second fossil record to the southernmost in North America, and further supports the idea that several genera that grow in Mexico today were present in the area since the Miocene.
