REVISlON, PHYLOGENY AND COMTS ON BIOGEOGRAPHY OF SOAPFISHES OF THE GENUS RYPTICUS (TELEOSTEI: SERRANIDAE)

摘要

Soapfishes of the Atlanto-East Pacific genus Rypticus are reviewed. Rypticus macroshous Courtenay and R. brachyrkinus Cowtenay are junior sguonmps of R. bornoi Beebe and Tee- Van and R. randalli CoUrtenay respecthely A phylogenetic analysis of the genus based on outgroup comparison with other members of the tribe Graministini indicates Rypticus is a monophyletic lineage supported by sir modifications in axial-skeleton structure C and reduc- tion in the number of infraorbital bones. A single, fully resolved the illustrates the hypoth- esized relationships among species. Some of the cladogenetic events hypothesized based on morphology are corroborated by vicariant biogeography
