Zuytdorpensis is a new form of ketyana described by Felix Lorenz and Marco Chiapponi. The description was published late in 2024 in Molluscan Science Volume 6. In the area west of the Southern Zuytdorp Cliffs and to the east of Big Bank is a populated by dwarf rosselli and ketyana. This is northwest of Kalbarri. This form of ketyana we find in the same area as we collect praeclara off the southern Zuytdorp Cliffs. They are consistently small with pepper spotted dorsums and bases that vary a great deal in colour. This slender specimen was ROV collected from sand in 78 meters of water at Zuytdorp Cliffs South during August 2024. It has a pinky/ cream coloured dorsum with tiny tan specks and vibrant orange and white base. Graded Fine+ + as a hint of a fold can be felt and the anterior siphon is chipped.
