Morphological analysis and taxonomical status of four fish species of the genera Opisthocentrus and Pholidapus (Perciformes: Stichaeidae)

Morphological analysis and taxonomical status of four fish species of the genera Opisthocentrus... No common opinion on the systematics position of species of the fishes of the subfamily Opisthocentrinae, Stichaeidae family has been formed up to the present. Therefore, a morphological analysis of fishes belonging to taxa Opisthocentrus ocellatus, O. tenuis, O. zonope, and Pholidapus dybowskii was undertaken. The obtained data treated by various methods of statistics implied the species independence of these taxa, which sympatrically occurred in the coastal areas of the northwest of the Sea of Japan. All the four studied species were similar in some attributes and distinct by other. Minor differences in the structure of the seismosensory system of Ph. dybowskii and Opisthocentrus species gave no basis on which to distinguish the independent genus Pholidapus. It would be correct to consider this as a subgenus of the Opisthocentrus genus, which includes three other species. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Marine Biology Springer Journals

Abstract

No common opinion on the systematics position of species of the fishes of the subfamily Opisthocentrinae, Stichaeidae family has been formed up to the present. Therefore, a morphological analysis of fishes belonging to taxa Opisthocentrus ocellatus, O. tenuis, O. zonope, and Pholidapus dybowskii was undertaken. The obtained data treated by various methods of statistics implied the species independence of these taxa, which sympatrically occurred in the coastal areas of the northwest of the Sea of Japan. All the four studied species were similar in some attributes and distinct by other. Minor differences in the structure of the seismosensory system of Ph. dybowskii and Opisthocentrus species gave no basis on which to distinguish the independent genus Pholidapus. It would be correct to consider this as a subgenus of the Opisthocentrus genus, which includes three other species.
