[Larvogenesis of the diplocyst of Aploparaksis furcigera (Rud., 1819) Fuhrmann, 1926 (Cestoda, Hymenolepididae)].
Data are given on the larvogenesis of the diplocyst of Aploparaksis furcigera. The invagination process of the metamere is described. The external layer of duplicature (exocyst) of the diplocyst has been shown to be a derivate of typical cerecomere. Due to this the larvogenesis of the diplocyst of A. furcigera is regarded as a cystocercoid larvogevesis changed by the adaptation to parasitism in polymyarian intermediate hosts (Oligochaeta). The origin of protective cenogeneses of diplocyst is a response to mechanical effects of the cutaneous-muscular sac of Oligochaeta upon the developing larvocyst.
