Two new sensory receptors inGyrodactylus sp. (Platyhelminthes, Monogenea, Monopisthocotylea)

Two pairs of sub-surface ciliary aggregations, not previously described in gyrodactylid monogeneans, have been found in the antero-dorsal region of adultGyrodactylus sp. One pair lies more anteriorly and has seve...

Ultrastructure of sperm and spermiogenesis ofPterastericola astropectinis (Platyhelminthes, Rhabdocoela, Pterastericolidae)

During development of the spermatid, two free flagella are transported distally from the main spermatid mass by elongation of the shaft. They rotate back towards the shaft and lie parallel with it prior to fus...
