  • New developments in Pelagiidae taxonomy and phylogeny (Cnidaria: Scyphozoa: Semaeostomeae)
    Avian, Massimo ...
    This study provides new and additional data on morphology and a phylogenetic inference of all genera included in Pelagiidae family, comprising the recently described species Pelagia benovici Piraino, ... Aglieri, Scorrano & Boero, 2014, from the Northern Adriatic (Mediterranean Sea). The cladistic analysis of 32 morphological characters, of which the most significant are marginal tentacles anatomy, basal pillars, gonad pattern, subgenital ostia, and exumbrellar sensory pits, revealed significant differences from the currently known pelagiid genera Sanderia, Chrysaora, and Pelagia, with Cyanea as the outgroup. The most parsimonious trees were obtained by branch-and-bound search (PAST v. 2.17) and morphological characters were considered unordered in the cladistic analysis due to many unresolved homoplasies and unknown evolution of characters. The most parsimonious tree supports a closer relationship between Sanderia and Chrysaora, and with Pelagia as sister taxon. The phylogenetic relationships among genera in Pelagiidae family were inferred by Bayesian approach analyzing mitochondrial genes (COI, 16S rDNA, 12S rDNA) and nuclear ribosomal genes (28S rDNA, ITS1/ITS2 regions) and again Cyanea as the outgroup. The results of combined data sets, morphological and gene sequences (mtDNA, 28S and ITS), gave congruent results with the gene tree. Phylogenetic inference confirmed a closer relationship of the new species, P. benovici, with gen. Sanderia and Chrysaora, than with gen. Pelagia.
