Maximum likelihood tree inferred from the concatenated matrix (CO1 + ITS2) of Loxosceles species from Mexico. Colors of branches and bars indicate different species. Numbers above bars at right represent the delimitation methods: 1: morphology (M). 2: neighbor-joining (NJ). 3: ABGD with initial partitions (IP). 4: ABGD with recursive partitions (RP). 5: GMYC. 6: bPTP with ML. 7: bPTP with IB. Numbers below bars represent species recovered for each delimitation method. Red numbers correspond to Bayesian posterior probabilities, and black numbers are bootstrap support values from the ML analysis.
