A. BI molecular phylogenetic tree for Amphithrax verrucosus, A. aculeatus and other selected species within the family Mithracidae MacLeay, 1838. Based on GTR+G nucleotide substitution model on the concatenated dataset for two mitochondrial (12S, 16S) and one nuclear (ITS-1) genes, represented as a maximum likelihood phylogram with Bayesian posterior probabilities and maximum likelihood bootstrap values (black diamond = ≤ 50% support, * = 16S sequences only). Note: ULLZ’s 9148 and 4534, of Windsor and Felder (2014) and 13596 all re-identified as Amphithrax verrucosus (H. Milne Edwards, 1832); B. Amphithrax verrucosus (H. Milne Edwards, 1832), male (CW: 40.7 mm; CL: 29.5 mm), Barbados (BLSZ 218); C. Amphithrax aculeatus (Herbst, 1790), juvenile female (CW: 53.8 mm; CL: 44.0 mm), Barbados (BLSZ 217).
