Abstract

The taxonomic identity of the common subtidal ctenostomate bryozoan Alcyonidium diaphanum is resolved using comparative morphological and molecular genetic techniques. The newly recognized lectotype series and topotype specimens are described and illustrated. The incorporation of spicules and foreign particles during colony growth is described. Colony morphology and genetic characters of the three commonly occurring morphotypes are examined, showing that just a single genetic species may be recognized, based on the 12s rRNA and CO1 mtDNA genes. Mitochondrial haplotypes show no general correlation with either colony morphotype or geographical location.
