Amblypygi (whip spiders) are terrestrial chelicerates inhabiting the subtropics and tropics. In morphological and rRNA-based phylogenetic analyses, Amblypygi cluster with Uropygi (whip scorpions) and Araneae (spiders) to form the taxon Tetrapulmonata, but there is controversy regarding the interrelationship of these three taxa. Mitochondrial genomes provide an additional large data set of phylogenetic information (sequences, gene order, RNA secondary structure), but in arachnids, mitochondrial genome data are missing for some of the major orders. In the course of an ongoing project concerning arachnid mitochondrial genomics, we present the first two complete mitochondrial genomes from Amblypygi. Both genomes were found to be typical circular duplex DNA molecules with all 37 genes usually present in bilaterian mitochondrial genomes. In both species, gene order is identical to that of Limulus polyphemus (Xiphosura), which is assumed to reflect the putative arthropod ground pattern. All tRNA gene sequences have the potential to fold into structures that are typical of metazoan mitochondrial tRNAs, except for tRNA-Ala, which lacks the D arm in both amblypygids, suggesting the loss of this feature early in amblypygid evolution. Phylogenetic analysis resulted in weak support for Uropygi being the sister group of Amblypygi.
