Lithocarpus dahuensis, a new Fagaceae species from Fujian Province, China, is described and illustrated. The new species is morphologically similar to L. konishii, but its oblanceolate leaf blade has more pairs of acute teeth on the margin, denser lateral veins, smaller cupules enclosing up to 1/4–1/3 of the nut, and its nut is only half as long as those of L. konishii. The plastome of L. dahuensis was 161,303 bp in length and displayed the typical quadripartite structure. Phylogenetic analyses distinguished L. dahuensis from L. konishii with strong support based on whole plastome and nrITS, respectively.
