Terranova pectinolabiata n. sp. is described from the great hammerhead, Sphyrna mokarran, from Australian waters. This represents the first report of a species of Terranova from the host species. The new species is characterised by the morphology of the caudal plates and labia. ITS sequences were obtained for 20 specimens which were identical, despite morphological variation that has traditionally been indicative of separation of species. Additionally, genetic analyses confirmed the identification of the larval Terranova Type II previously reported in Australian and New Caledonian waters as Terranova pectinolabiata n. sp.
特兰诺瓦氏栉鳞鲨新种描述于来自澳大利亚水域的大锤头鲨，双髻鲨属。这是首次在宿主物种中报告特兰诺瓦氏栉鳞鲨的物种。新种的特征在于尾鳍板和阴唇的形态。对 20 个标本进行了 ITS 序列分析，尽管形态变异传统上表明物种的分离，但这些标本的序列是相同的。此外，遗传分析证实了先前在澳大利亚和新喀里多尼亚水域报道的幼虫特兰诺瓦氏栉鳞鲨 II 型为特兰诺瓦氏栉鳞鲨新种。
