Von den Spermazellen konnten, allerdings nur am lebenden Objekt, folgende zwei Typen erkannt werden: 1. (Bilder 36 und 37) Der fadenförmige Körper erweitert sich an beiden Enden oval. Das breitere Ende, das bei der Bewegung vorangeht, trägt noch einen fadenförmigen Fortsatz. In der hinteren Erweiterung befinden sich drei bis fünf dunkle Punkte, die vermutlich Chromatinbrocken darstellen. 2. (Bild 39) Beim Typus 2 der Samenzelle trägt der lange fadenförmige Körper nur vorn eine Erweiterung. Sie hat keinen Fortsatz und enthält caudal ein Körperchen, anscheinend den Kern.

The penial tube has a slight bend at its proximal end, and a distinct and sharp bend at its distal end. The distal tip of the stylet is blunt with a terminal opening. The walls appeared of uniform thickness along the length of the tube. p. 56
