摘要: Abstract The mature Helicometroides atlanticus spermatozoon exhibits an anterior electron-dense material, two axonemes of the 9 + “1” pattern, a nucleus, mitochondria, extramembranous ornamentations located at level first mitochondrion and cortical microtubules arranged into fields: ventral field corresponding to mitochondrial side dorsal nuclear side. It lacks spine-like body cytoplasmic expansion as in Monorchis parvus only species Monorchioidea which has been described until now. Nevertheless, it is distinguished from M. by presence material appear one after other.
