Revision, phylogeny and comments on biogeography of soapfishes of the genus Rypticus (Teleostei: Serranidae)
Abstract:Soapfishes of the Atlanto-East Pacific genus Rypticus are reviewed. Rypticus macrostigmus Courtenay and R. brachyrhinus Courtenay are junior synonyms of R. bornoi Beebe and TeeVan and R. randalli Courtenay respectively. A phylogenetic analysis of the genus based on outgroup comparison with other members of the tribe Grammistini indicates Rypticus is a monophyletic lineage supported by six modifications in axial-skeleton structure and reduction in the number of infraorbital bones. A single, fully resolved tree illustrates the hypothesized relationships among species. Some of the cladogenetic events hypothesized based on morphology are corroborated by vicariant biogeography.
