Figure 2 - The analysis results of some species from the COI-670 dataset. The analysis results based on other genes were almost identical. The NJ tree was constructed based on the Kimura 2-parameter (K2P) model with a bootstrap value over 50% displayed. The gray blocks behind the tree represent the putative species, which means that the taxa in the tree corresponding to a single block are in one putative species. The number of blocks express the number of putative species using this method. A Chaitophorus saliniger B Laingia psammae.
