(a) Phylogenetic tree of Platyhelminthes with Gastrotricha as sister group reconstructed from several sources [1, 6, 7]. Squares with grey background indicate the number of species with published mitochondrial genomes in the respective taxon. Pink background indicates newly sequenced species in this study. (b) Mitochondrial gene orders representative for the taxa displayed on the phylogenetic tree on the left. Only ribosomal and protein-coding genes are considered. Colours follow the widely conserved gene cartridges indicated by Mwinyi et al. [18]. Putative lophotrochozoan ground pattern after Bernt et al. [14]. Possible gastrotrich ground pattern with the single sequenced species, Lepidodermella squamata [1]. Possible catenulid ground pattern with the single newly sequenced species, Stenostomum sthenum. Duplicated genes in red, transcription from the minus strand is indicated by rectangle outlined in red. Possible macrostomorphan ground pattern with the single complete newly sequenced species, Macrostomum lignano. Possible polyclad ground pattern represented by Prosthiostomum siphunculus [2]. Triclad ground pattern after several sources [3,4,5]. Neodermatan ground patterns after Wey-Fabrizius et al. [9]. Putative flatworm ground pattern calculated with TreeREx (present study)
