Overview of ptyctimous box mites from a soil and deadwood extraction (a) and comparison of the four taxa (b-j). a Euphthiracaroidea originated mostly from the deadwood samples, whereas Phthiracaroid mites originated from the leaf litter samples. Photographic (b-e) and schematic (f-j) ventral overview of specimens of Archegozetes longisetosus (b, f), Euphthiracaroidea (c, g), Phthiracaroidea (d, h) and the genus Steganacarus (e, j) used in the experiment. Blue, notogaster; green, coxisternum and legs (cut off); orange, prodorsum; red, (holo-)ventral plates; yellow, anogenital membrane in A. longisetosus (f) and plicature plates in Euphthiracaroidea (g). The anogenital membrane in Phthiracaroidea (h, j) is hidden behind the ventral plates and within the idiosoma
