New shallow water species of Caribbean Ircinia Nardo, 1833 (Porifera: Irciniidae)

Abstract

Seven Ircinia morphospecies were collected from three sites in the Caribbean (Bocas del Toro, Panama; the Mesoamerican Barrier Reef, Belize; and the Florida Keys, United States of America). Previous research used an integrative taxonomic framework (genome-wide SNP sampling and microbiome profiling) to delimit species boundaries among these Ircinia. Here, we present morphological descriptions for these species, six of which are new to science (Ircinia lowi sp. nov., Ircinia bocatorensis sp. nov., Ircinia radix sp. nov., Ircinia laeviconulosa sp. nov., Ircinia vansoesti sp. nov., Ircinia ruetzleri sp. nov.) in addition to one species conferre (Ircinia cf. reteplana Topsent, 1923).
