Abstract
Previous studies of the endocrine organs and frontomedial ocelli of the Isopoda revealed that structural differences exist in the hitherto observed suborders. The Phreatoicidea, the oldest known suborder, are studied for the first time. A Bellonci organ was not discovered. The sinus gland has a globular form, it seems to be linked with the lateral cephalic nerve plexus. Similar sinus glands are known from the Oniscidea. The median ocelli are reduced to the number of 3, while other Isopoda may have 2 to maximally 5 ocelli.
