Comments: Most Gymnodamaeidae   have a large, cup-like tectum on trochanters III and IV that protects the trochanteral-femoral joint; however, species of Adrodamaeus   have similar retrotecta protecting their distal leg joints as well ( Figs. 13–14 View FIGURES 9 – 14 ). Since predators of adult oribatid mites often attack these mites at their leg joints, snipping off legs and penetrating to the hemolymph ( Molleman & Walter 2001), it seems likely that retrotecta evolved in response to predation pressure. This genus is similar to Arthrodamaeus Grandjean, 1954   a (see Bayartogtokh & Weigmann 2005) and may be a junior synonym (G. Weigmann, Institute for Zoology, Freie Universitaet Berlin, pers. comm.).
