Dear colleagues and friends It is my pleasure to share with you the results of my study on phylogeny of the Cerithioidea. This Museum has started the distribution of the paper recently published (reference below). I have performed a detailed anatomical study of 19 species (3 new) of 12 families of cerithioideans and obtained a cladogram. The results show the monophyly of the superfamily that encompasses the “Campaniloidea” and the “Vermetoidea”. The paper is the first of a series I have done during my doctoral project on phylogeny of the order Caenogastropoda. Each paper focuses a superfamily. The study on the Stromboidea, Calyptraeoidea and Cypraeoidea are in editorial process. The publications on remainder superfamilies and on the whole order are still being done.
