title: [Dactylogyrids (Monogenea: Dactylogyridea) with unusual number of the anchors, their origin and phylogenetic significance. Original data].
abstract: The haptors Dactylogyrus spp., Anacanthorus sp., Trianchoratus sp. and Schilbetrematoides pseudodactylogyrus are investigated. On the base of the morphology, transfer of the domus, etc. a homology of the hooks in dactylogyrids (s. s.) and the pin-like structures (4 "A") in the haptor of Anacanthorinae and Dactylogyridae sensu Bychowsky et Nagibina, 1978 is demonstrated. The vestiges of the anchors in the haptor of dactylogyrids (s. l.), according to morphological data, correspond to the point of anchor formed during the ontogenesis. In S. pseudodactylogyrus the pins are redescribed as typical vestiges of the anchors.
