The Newsletter MOTax (Marine Organisms Taxonomy) is officially created. The publication will be targeted to receive and disseminate information concerning the taxonomy activities (publications, events, courses, etc.), and will represent a tool to foster the exchange of information within the the Italian community of marine taxonomists. The number zero is a special issue entirely dedicated to the First Workshop MOTax which was held at the Zoological Station on 26 and 27 October 2016. The newsletter will be published quarterly.
