Resolving phylogenetic and classical nomenclature: A Revision of Canarium Schumacher, 1817 (Mollusca, Neostromboidae, Strombidae)

Abstract

This revision of the genus Canarium Schumacher, 1817 after Abbott (1960) advances our understanding of the phylogeny of Strombidae. Morphological characters were used to generate a phylogeny using maximum likelihood and including all of the recognised species. This resulted in the recognition of one tree, and within that tree the existing genera Canarium Schumacher, 1817 Tridentarius Kronenberg & Vermeij, 2002 and Terestrombus Kronenberg & Vermeij, 2002, and two more Maculastrombus n. gen. and Neostrombus n. gen. were recognisable clades. Furthermore, within the genus Canarium, four subgenera, Canarium (Canarium), Canarium (Conundrum), Canarium (Elegantum), and Canarium (Stereostrombus), were identified and described. We describe and define taxa that are compatible with the requirements of the International Code of Phylogenetic Nomenclature (PhyloCode 2020), and also conform to the requirements of the International Code of Zoological Nomenclature (ICZN 1999). This revision assists in generating a system of nomenclature that reflects the hypothetical relationships, and is at the same time practical in its application. We designate type localities and types for included species that were not yet addressed up until now.
