Triboniophorus is a genus of air-breathing land slugs, terrestrial pulmonate gastropod molluscs in the family Athoracophoridae, the leaf-veined slugs.
Species within this genus include:
Triboniophorus brisbanensis <small>Pfeiffer, 1900</small>: Synonym of Triboniophorus graeffei (anatomy at page 316.)
These slugs have two, not four, tentacles, and like other leaf-vein slugs they have an indented pattern on their dorsum which resembles the veins of a leaf.
