Redescription and Relationships of Parasphyraenops Atrimanus Bean (Pisces: Serranidae), with Discussion of Other Bermudian Fishes Known Only from Stomach Contents
Parasphyraenops atrimanus Bean, an apparent Bermuda endemic known only from two specimens, is redescribed. Originally placed in the Cheilodipteridae, P. atrimanus is shown to be a planktivorous serranid belonging to the subfamily Serraninae. It is hypothesized to be most closely related to Serranus incisus and S. luciopercanus, based on unique modifications of the infraorbital series. A novel specialization of P. atrimanus is the configuration and articulation of its lacrimal, but otherwise this fish is remarkably similar to S. incisus, also a planktivore; the two species exhibit at least seven synapomorphies. Accordingly, we assign S. incisus to Parasphyraenops. Two additional fish species, Sebastes paucispinis and Cepola sp., recorded from Bermuda solely from stomach contents, are discussed.
