In this pre-radular region, the foregut runs almost parallel to the pedal groove. The foregut has a very glandular epithelium, and it is surrounded by longitudinal musculature (5 to 7.5 μm). In the radular region, the longitudinal musculature layer surrounding the foregut is reinforced with a layer of circular musculature (

The pericardioducts are narrow (55 μm long, 5 to 7.5 μm in diameter) and join to the dorsal surface of the spawning duct in its middle region. The spawning ducts are completely fused into a single tube. In its anterior region, the lumen of the fused spawning duct is wide (12.5 to 22.5 μm in diameter) and surrounded by a thick glandular layer (20 μm). As the spawning duct narrows, the glandular layer becomes thinner, as does the outer layer of longitudinal musculature (2.5 to 3.25 μm), before discharging centrally into the mantle cavity. No copulatory stylets or other accessory reproductive structures were observed.
