The mitochondrial gene arrangements of the pseudoscorpions Paratemnoides elongatus, Pseudogarypus banksi, and the ancestral chelicerate. The circular mt genome is depicted as linearized at the 5' end of the CO1 gene. The one letter amino acid code is used to designate the tRNA genes, with L1 = CUN; L2 = UUR; S1 = AGN; S2 = UCN. A + T is used to designate the putative control region. Genes above the medial line are encoded on the major strand, while those below the line are encoded on the minor strand. The green shading indicates genes that are in a different location than the ancestral gene arrangement, while the yellow shading indicates genes that are in the same location, but opposite strand, from the ancestral arrangement. Grey shading indicates a repetitive sequence insertion.
