DNA barcode tree of Papiriodes jacobsoni in Taiwan based on neighbor-joining analysis and Kimura’s two-parameter model. The specimens analyzed form two genetically distinct lineages, L1 and L2 (A), corresponding to populations in northern and central Taiwan, respectively. Two color-morphs, “spotty” (B) and “milky” (C), can be found in both lineages. Specimens are labels with their NTUM catalog numbers followed by a symbol denoting their color-morphs. Numbers around nodes are bootstrap values.
