Larval and Adult Stages of the Stromateoid Fish Psenes Regulus with Comments on its Classification
Abstract:A series of 21 specimens of Psenes regulus Poey from the Western North Atlantic is described and seven specimens are figured, including specimens larger and smaller than previous descriptions. Graphs of body proportions are presented to show developmental changes. Changes in body depth are strikingly different from the genotype, Psenes cyanophrys. Other differences are the relatively low soft-ray counts of dorsal and anal fins, a slender caudal peduncle bearing keels and a stiff, widely forked caudal fin. These suggest a closer relationship to the genus Ariomma than to Psenes in the admittedly unsatisfactory classification of the stromateoid fishes. Psenes regulus, Cubiceps dollfusi, Cubiceps nigriargenteus, Cubiceps melanus and Paracubiceps ledanoisi are allocated to the genus Ariomma. The reasons for this are discussed.
Available data indicate that P. regulus is a tropical, marine fish which is occasionally found in more northerly areas of the Gulf Stream.
Postlarval and prejuvenile specimens are generally taken over deeper waters than those where juveniles and adults are taken.
