On the Genus Fusinus in Japan V: Further Species, an Unnamed Form and Discussion

Abstract

In the concluding paper of the series, the authors address a number of names that have been cited erroneously in literature as belonging to the genus Fusinus and/or occurring in Japan. Two forms that until now had not been assigned to named species are identified as further variants of F. perplexus, a third unnamed form is figured and there is brief discussion of some related genera and species. The identity of Fusinus beckii (Reeve, 1848) is confirmed by the rediscovery of its lectotype and a second specimen from the Andaman Islands. Though originally described as a subgenus of Fusinus, Chryseofusus Hadorn & Fraussen, 2003 is here accorded full generic status. Lectotypes are selected for Fusinus beckii (Reeve, 1848) and F. gracillimus (Adams & Reeve, 1848). Fusus solidulus A. Adams, 1864 is considered a nomen dubium.
