Distance tree of Svistella species based on COI genes. Rooted by Amusurgus genji, the tree was constructed using the neighbor-joining (NJ) method with the Kimura 2-parameter model and a 0.19 gamma parameter. Topology supports of major nodes are indicated above branches by bootstrap value. Two DNA barcode-based (ABGD, ASAP) delimitation methods are represented by vertical bars in grey and blue, respectively, on the right side of the tree.
