title: [Possible evolutionary scenarios in the parasitengona mites (Acariformes: Parasitengona) based on anatomical peculiarities of their digestive system].
abstract: Five possible evolutionary scenarios of the higher acariform mites from the cohort Parasitengona are proposed on the basis of the detailed examination of anatomy of the excretory organ and midgut in the representatives of terrestrial mite families Trombiculidae and Microtrombidiidae, and in freshwater mite families Teutoniidae and Pionidae, on different developmental stages including parasitic larva. These scenarios explain possible ways of evolutionary transformation within the Parasitengona from one or several ancestor with the open digestive tract.
