is widely distributed in the Indo-West Pacific from southern India and Sri Lanka in the west, to Myanmar, Thailand, Indonesia (Java), Taiwan, China and the Philippines in the east (Compagno, 1984, 1988, 1998). This species was also previously documented as occurring widely across northern Australia (Compagno, 1984), and off Papua New Guinea (Last and Stevens, 1994). Stevens and Cuthbert (1983) documented substantial differences in tooth and vertebral counts between Australian specimens and material from Singapore, Thailand and Indonesia (see also Compagno, 1988). These authors provisionally identified the Australian form as
