Abstract

Scopelogadus bispinosus has been redescribed, its species status has been restored. It has long been considered a subspecies of S. mizolepis. The species inhabits mainly the tropical and subtropical zones of the central and eastern parts of the Pacific Ocean; in the northeastern Pacific Ocean, it is found in temperate waters. A new species S. perplexus sp. n. has been described from the tropical waters of the Pacific Ocean. The new species is characterized by the presence of a large number filaments of pseudobranch (10–11), the largest of the two branchial lobes opposite the angular gill raker is relatively short; the color of the stomach surface is uniformly dark, without noticeable darkening in the back.
