Chemically unknown tissue toxins from internal organs that may kill Pterostichus carabids are uniquely known from the milacid slug Tandonia budapestensis, which shows an aposematic coloration (orange dorsal line).
2012, A. South, Terrestrial Slugs: Biology, ecology and control, page 110:
The atrium is a simple structure in the Limacidae and in Milacidae but in some milacid slugs it is equipped with a stimulator (see Section 5.1.7) and, in most milacids, accessory or atrial glands open into the atrium.
