  1. List of taxa and mitogenomes for detailed initial scoring of mitochondrial group II intron presence. The respective numbers of group II introns are indicated. Taxon selection was aimed to maximize phylogenetic diversity within the respective clades. Care was taken to extract intron sequences with proper 5′- and 3′-termini. Asterisks indicate species not further considered for detailed group II intron sequence analyses owing to redundancy with other species within the respective group. A plus sign (+) in the IGS analysis column indicated careful inspection of intergenic sequences for the presence of intron fossils
