Bayesian posterior probabilities (PP; blue circles) and IQ-TREE ultrafast bootstrap support values (UFBoot; red triangles) are shown at the corresponding nodes; values of PP < 0.95 and UFBoot < 90 are omitted. The coloured bars on the right summarize the morphological identifications and the results of three COI - based molecular species-delimitation methods (ABGD, ASAP, and bPTP), with each colour representing a putative species or molecular operational taxonomic unit (MOTU). The fifteen major clades recovered in the phylogenetic analyses are labelled Clades A – O. The rightmost column shows the pereonite 2 tergites of representative specimens from the corresponding major clades.	Figure 3.
