Redescription of the goby genus Gobiosoma (Teleostei: Gobiidae: Gobiosomatini), with the synonymy of the genus Enypnias

摘要

Previous classifications of the American gobiid genus Gobiosoma (Teleostei: Gobiidae: Gobiosomatini) have rendered the genus polyphyletic or paraphyletic based on our current understanding of the Gobiosomatini phylogeny. We offer a new definition for Gobiosoma that renders the genus monophyletic. Our new classification synonymizes the genus Enypnias with Gobiosoma and provides characters to distinguish Gobiosoma from allied genera, including Elacatinus and Tigrigobius. Redescriptions and colour photographs of the poorly known species Gobiosoma aceras (formerly Enypnias aceras) and Gobiosoma seminudum (formerly Enypnias seminudus) are provided.
