Monterosato (1877d: 416) described H. secernenda as a form (smaller, flat, dark coloured, with a sculpture of weak cords only, more iridescent, and with straight peristome) of Haliotis lamellosa Lamarck, 1822 . Later, he raised the name to specific rank (1884a: 104), making it available since the original date of publication, viz. 1877 ( ICZN, 1999: art. 45.6.4.1 ). MolluscaBase (2018) records Haliotis tuberculata var. secernenda in the synonymy of H. tuberculata tuberculata based on Geiger & Poppe (2000) . However, the shell characters of H. secernenda are the same diagnostic for H. mykonosensis Owen, Hanavan & Hall, 2001 [new synonymy] (see also Geiger & Owen, 2012 ).
