Phylogenetic reconstruction of Baetiella species based on Bayesian inference (BI) and Maximum likelihood (ML) analyses of sequences of the mitochondrial COI gene. The highlighted clades represent the newly described Baetiella species from Thailand with high bootstrap and Bayesian posterior probabilities (BS/PP) supporting. Pink circles on branches indicate PP > 0.9. Colored vertical boxes indicate species-delimitation hypothesis (i.e., MOTUs) according to the ASAP and mPTP methods.
