Diodon nicthemerus Cuvier, 1818

Leis (1978) examined nine specimens of Diodon nicthemerus Cuvier (1818, ref.18059), all from southern Australia.Museums in Australia contain large numbers of this species, and its distribution is confirmed as being confined to the waters of southern Australia. I have seen specimens from an area ranging from Houtman Abrolhos Is., WA (28 oS), to Nadgee, NSW (37 oS), although Kuiter (1993) reports D. nicthemerus as far north as Seal Rocks (32 oS). This is the most restricted distribution of any species of Diodon .
