Type species: Cardiodectes medusaeus ( Wilson, 1908 ) accepted as Cardiodectes bellottii ( Richiardi, 1882 ) ( type by original designation). Wilson (1908) described Lernaeenicus medusaeus Wilson, 1908 , and transferred Peroderma bellotti Richiardi, 1882 into the genus Lernaeenicus Lesueur, 1824 . Later on, Wilson (1917) established the genus Cardiodectes Wilson, 1917 to transfer both Lernaeenicus medusaeus Wilson, 1908 and Lernaeenicus bellotti ( Richiardi, 1882 ) and designated the former [= Cardiodectes medusaeus ( Wilson, 1908 ) ] as the type species. Cardiodectes medusaeus ( Wilson, 1908 ) was later synonymized with Cardiodectes bellottii ( Richiardi, 1882 ) .
