Two specimens of a rare deep-sea anglerfish, Himantolophus azurlucens Beebe and Crane, 1947, were collected off the Pacific coast of northern Japan, representing the first records from the western North Pacific. These specimens represent the second and third records of the species since the original description, which was based on a single specimen from the eastern North Pacific; we determined that a previous record from the Atlantic was erroneous. We herein provide a description of the specimens and comments on intraspecific variation of the escal appendages. The new Japanese name “Masamori-chouchin-anko” is proposed for H. azurlucens. In addition, we provide DNA barcode sequences of the recently collected specimens of Himantolophus Reinhardt, 1837, including H. azurlucens and the fourth record of H. borealis Kharin, 1984, and demonstrate remarkably low intraspecific genetic variation of cytochrome c oxidase subunit I within the genus.

While examining specimens identified as Paracaristius maderensis (Maul, 1949) at the Scripps Institution of Oceanography Marine Vertebrate Collection, we encountered an individual of the genus Platyberyx Zugmayer, 1911. This specimen was collected in the Central Pacific Ocean, 900 km east of Wake Atoll during the Naga Expedition 1959–1961. We identified the specimen as Platyberyx rhyton Stevenson and Kenaley, 2013, and it represents the first record of this species outside of Japanese waters. This is a range extension of around 3400 km east for this species, as well as the first record of a juvenile individual and the fourth record of the species overall. We provide a morphological description and comparisons to the three previously known adult specimens.
