Reproductive organs and spermatogenesis of the peculiar spermatozoa of the genus Kryptodasys (Gastrotricha, Macrodasyida), with an appraisal of the occurrence and origin of the tail-less spermatozoa in Gastrotricha

Summary: This study reports the presence of aflagellate spermatozoa in two species of the recently described genus Kryptodasys. The ultrastructure of these spermatozoa shows common features unique to the genus. The functional and phylogenetic significance of this aflagellate condition in the two studied taxa and other species is discussed in the context of the generally flagellate sperm in Gastrotricha.
