Here we evaluate the taxonomy of the marine gastropod genus Laevistrombus Abbott, 1960 and determine that there are five extant species within this genus, three of which occur in the southwest Pacific. Comparative analyses of this complex have been problematic due to the lack of designated type material. Therefore, we present the type material for L. canarium Linnaeus, 1758; L. taeniatus Quoy Gaimard, 1834; and L. vanikorensis Quoy Gaimard, 1834. Current taxonomy has L. vanikorensis absorbed within the L. canarium complex. L. taeniatus is generally held to be a synonym of L. turturella Röding, 1789. We demonstrate that both L. taeniatus and L. vanikorensis are distinct species and reinstate both to species level. Our revision also notes the significant variability in early teleoconch structure within the geographic range of L. vanikorensis, and highlights the need for a greater revision of Laevistrombus, given the diversity in early teleoconch morphology present in southwest Pacific species.
在此，我们对1960年艾伯特所命名的海洋腹足纲动物Laevistrombus属进行分类学评估，并确定该属现存五个物种，其中三个分布在西南太平洋。由于缺乏指定的模式标本，对这个类群的比较分析一直存在问题。因此，我们展示了1758年林奈所命名的L. canarium、1834年奎伊和盖马尔所命名的L. taeniatus以及1834年奎伊和盖马尔所命名的L. vanikorensis的模式标本。当前的分类学将L. vanikorensis归入L. canarium类群。L. taeniatus通常被认为是1789年罗丁所命名的L. turturella的同义词。我们证明L. taeniatus和L. vanikorensis都是独特的物种，并将它们都恢复到物种级别。我们的修订还指出了L. vanikorensis地理分布范围内早期螺层结构的显著变异性，并强调鉴于西南太平洋物种早期螺层形态的多样性，有必要对Laevistrombus属进行更全面的修订。
