The ventrolateral foregut glands are fused into a narrow duct (7.5 μm in diameter) where they attach ventrally to the foregut anterior to the subradular pouch. For most of their length, however, these glands are paired (20.5 to 30 μm in diameter) and extend posteriorly on either side of the foregut (

system: A precise reconstruction of the posterior region of the body was not possible to perform, but the general arrangement of the reproductive apparatus could be determined, from which no remarkable characteristics were observed. The spawning ducts are completely fused as a single duct (12.5 μm high and wide), with a thin musculature it opens centrally into the mantle cavity. The pericardioducts are small, without seminal vesicles, and ventrally connected with the posterior part of the pericardium.
