Phylogeny of Strombidae (Gastropoda) Based on Mitochondrial Genomes

The marine gastropod Strombidae is widely distributed in tropical and subtropical regions all over the world possesses high morphological diversity. In order to better understand how characteristics evolved within Strombidae, a robust phylogenetic framework needed. present study, complete mitochondrial genomes of Lentigo lentiginosus , Euprotomus aratrum Canarium labiatum were sequenced. three newly sequenced mt contained 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal (rRNA) several non-coding regions, indicating similar pattern with respect genome size, gene order, nucleotide composition compared those other strombids reported before. Two different datasets derived from constructed resolve internal relationships Stromboidea Strombidae. Within Stromboidea, sister group formed by Clade I [Rostellariidae + (Seraphsidae Strombidae)] II [Xenophoridae (Struthiolariidae Aporrhaidae)] fully recovered supported synapomorphies as previously suggested. positions L. E. C. confirmed similarities observed corresponding phylogeny. A correlation between speciation events paleoclimate change was presumed. Our results indicate that would be promising tool reconstruct phylogeny an increased taxon sampling future.
