Bayesian Inference (BI) phylogenic tree based on COI showing the phylogenetic relationship between Eusirus carolinus sp. nov. and related eusirids, with bootstrap replications (BS) labeled (>50). Putative species identified by DNA-based species delimitation methods [Automated Barcode Gap Discovery (ABGD) and Bayesian implementation of the Poisson Tree Processes (bPTP)] applied to the COI tree/distance matrices are indicated by bars on the concatenated tree. Color codes indicate the support of each putative species.
