Athoracophorus bitentaculatus, is a native species of air-breathing, terrestrial, pulmonate, gastropod molluscs in the family Athoracophoridae. Athoracophorus bitentaculatus is one of only three named species of leaf veined slugs in the North Island, and this is by far the most common. It is also present in the South Island. The other two present in the North Island are Pseudaneitea papillata (large, olive colour, with noticeable papillae), and Athoracophorus suteri (blackish-brown, with whitish papillae and grooves).
