Leptochiton collusor (Iredale & Hull, 1925)

Leptochiton collusor is similar to many other Australian and New Zealand leptochitons with longitudinal rows of granules on the central area of intermediate valves and bidentate cusps of the major lateral teeth of the radula, but differs from them by having smooth, elongate, needle-like spicules at the dorsal girdle, and a mucro that is a little behind the center. L. collusor differs from the deep-water species L. laurae that has narrow dorsal girdle scales, by having radial rows of granules on the head valve, lateral areas of intermediate valves and postmucronal area of tail valve and according to Kaas & Van Belle (1985) a short, squarish central radular tooth.
