Das Stilett hat die Gestalt eines leicht gekrümmten Trichters mit terminaler Öffnung, die auf einer Seite von einer halbkreisförmigen Verdickung umgeben ist. Je nach der Betrachtungsrichtung sieht das Kopulationsorgan daher etwas verschieden aus. p. 31 (bzw. 391)

Die Augen sind sehr schwach entwickelt, bei oberflächlicher Beobachtung erscheint das Tier sogar völlig augenlos. Die Pigmentbecher setzen sich aus sehr wenigen (3-7) schwach rötlichen Pigmentkörnchen zusammen. Die geringe Entwicklung des Augenpigments ist offenbar eine Reduktionserscheinung im Zusammenhang mit der Besiedlung des lichtabgeschlossenen Küstengrundwassers. Die Wandungen des Stiletts bilden am distalen Ende eine kugelförmige Anschwellung aus. p. 482

Das chitinöse Kopulationsorgan bildet ein langes distal allmählich verschmälertes, gerades Rohr, dem am Ende ein unter stumpfem Winkel abbiegender Zipfel ansitzt. Die Mündung dürfte durch eine Öffnung in gerader Fortsetzung des Rohres erfolgen. Die Seitenränder des spitz zulaufenden Zipfels sind, wie Schnitte zeigen, etwas aufwärts gebogen. p. 15

The sperm cell is a thin filament with a small knobbed head containing granules. Setae are lacking in this cell. It is this present author's opinion that Okugawa has depicted an immature sperm cell. p. 205
