. Ciliated duct to mantle cavity present anterior to coiled seminal vesicle. Anterior spermiduct ciliated, moderately muscular, passes forward embedded in body wall from mantle cavity duct to penis base. Long spermiduct loop in hemocoel leaves body wall near penis base and runs back alongside proboscis, then doubles back and enters penis. Spermiduct of internal loop wide, with clustery mucoidal epithelium that continues along most of the length of the penis except for a non-secretory region at the base. Penis tip with subepithelial mucus glands in addition to secretory epithelium. Penis long, relatively thick, simple with a short filament tip. Penis curled back in the posterior mantle cavity at rest.

, including a single gland mass, with muscular gonopericardial duct and no bursa copulatrix. Gland mass stains red (eosinophilic) in the middle, and pale purple (with haematoxylin) on both ends. The female sectioned had an egg capsule in the vestibule, which was otherwise short and thin-walled. Gonopericardial duct wide and coiled, epithelium cuboidal with large basal nuclei; duct has a wide, very thickwalled medial region (
