The locality details given by Quoy & Gaimard (1832: 148) indicate that the type material was collected in January 1827, when the French corvette Astrolabe was anchored in Astrolabe Roadstead, on the western side of Tasman Bay, northern South Island (see D’Urville 1830: 27–43; Wright 1950: 76–85). Limax bitentaculatus Quoy & Gaimard, 1832 is the type species of Janella Gray, 1850 , by monotypy, and also of Athoracophorus Gould, 1852 , by monotypy.
