FIGURE 2. Maximum Likelihood gene tree (highest log: -3749.87), constructed with COI barcode sequences of Ixchela. Colors in the branches indicate species; same colors are in the bars, which represent the different species delimitation methods used for their validation. Red branches + blue circles indicate the new species. Numbers below the bars represent the species recovered in each species delimitation method (not considering the outgroup: P. dugesi): 1: morphology (M). 2: neighbor-joining (NJ). 3: GMYC. 4: ABGD with recursive partitions (RP). 5: ABGD with initial partitions (IP). 6: bPTP with IB. 7: bPTP with ML. Numbers above branches are Bootstrap support values (>50% significant), number below are posterior probabilities (PP) support values under BI.
