Abstract

<p>With 59 Recent species, Bursidae, known as «frog shells», are a small but widely distributed group of tropical and subtropical gastropods that are most diverse in the Indo-West Pacific. The present study is aimed at reconstructing phylogenetic relationships of bursid gastropods based on extensive and representative taxon sampling. Five genetic markers (cytochrome c oxidase subunit I (cox1), 16&nbsp;s and 12&nbsp;s rRNA mitochondrial genes, 28&nbsp;s rRNA and Histone H3 nuclear gene) were sequenced for over 30 species in every known genus but Crossata. Furthermore, we sequenced the complete mt-genome of 9 species (10 specimens) (Aspa marginata, Marsupina bufo, Korrigania quirihorai, Korrigania fijiensis, Tutufa rubeta, Bursa lamarckii, Lampasopsis rhodostoma (twice), Bufonaria perelegans and Bursa aff. tuberosissima). Our analysis recovered Bursidae as a monophyletic group, whereas the genus Bursa was found to be polyphyletic. The genera Talisman and Dulcerana are resurrected and the genera Alanbeuella gen. nov. and Korrigania gen. nov. are described. Dating analysis using 21 extinct taxa for node and simplified tip calibrations was performed, showing a diversification of the group in two phases. Diversification may be linked to tectonic events leading to biodiversity relocation from the western Tethys toward the Indo-Pacific.</p>
