Raising names from the dead: A time-calibrated phylogeny of frog shells (Bursidae, Tonnoidea, Gastropoda) using mitogenomic data

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