| Abstract |
Ultrastructural features of the epidermis, gonads and photoreceptors are presented. The following features of Ciliopharyngiella intermedia are considered to represent autapomorphies of this species or of the taxon Ciliophatyngiella: the special design of egg shell-forming granules in vitellocytes, the pattern of marginal granules in germocytes,. an intercentriolar body with strong striated supporting beams, cilia with a pair of rootlets in young spermatids, as well as intracerebral photoreceptors with both ciliary and rhabdomeric light-sensing organelles arising from the same cell. Based on present information it is hypothesized, that Ciliophatyngiella represents the sister taxon of the Eulecithophora (= Prolecithophora + Rhabdocoela). |
