* values were obtained from the corresponding GenBank flat-file in the NCBI database (status January 10, 2009)

^a D = Dermatophagoides, Am = Amblyomma, As = Ascoschoengastia, C = Carios, H = Haemaphysalis, I = Ixodes, Le = Leptotrombidium, M = Metaseiulus, O = Ornithodoros, R = Rhipicephalus, S = Steganacarus, T = Tetranychus, U = Unionicola, V = Varroa, W = Walchia, Li = Limulus

^b S = Acari superorder (A = Acariformes, P = Parasitiformes)

^c PCG = Protein coding genes

^d duplications of the control region were also considered

^e Ref = References; unpub = unpublished

^f GC- and AT-skew for the strand coding for cox1, calculated following [46]

^g for these species the largest non-coding region(s) was/were assumed to be the control region(s)

^h L. pallidum has a duplication of 16S-rRNA; in this table the largest 16S-rRNA gene is considered

ⁱ only single copy genes were considered for protein coding gene length calculation of M. occidentalis

^jL. polyphemus belongs to the order of the Xiphosura within the class of the Merostomata
