That is the trouble. I have also contacted WoRMS but the fish editor has not updated this since 2008. Am trying to bring this to attention--thus the flag for curation--but realize that iNaturalist relies on FishBase/WoRMS for taxonomy.

Here is the recent barcode data indicating a separation of the two species:

Here is the review volume: https://www.caff.is/monitoring-series/451-marine-fishes-of-the-arctic-region-vol-1
p.77:
Taxonomy: Described by Pennant (1784) as Salmo catervarius from the mouth of the Kamchatka River at Avacha Bay and at Bering Island, and by Pallas (1814) as Salmo socialis from the islands between Asia and America. Both nominal species were later treated as synonymous with Müller’s (1776) Clupea villosa, described from Icelandic material. Mori (1930) described a new species, Mallotus elongatus, from the mouth of the Tumen River, Korea. Mallotus villosus sub- sequently came to be recognized as a circumpolar species. Although Schultz (1937) removed the Pacific population, M. catervarius, from the synonymy and redescribed it as a valid species, most authors did not follow Schultz (1937) and treated catervarius as a subspecies of M. villosus (e.g., Rumyantsev 1947, Schmidt 1950, Andriashev 1954, Wilimovsky 1954). Others used the name M. villosus socialis; e.g., Walters (1955) and Barsukov (1958). Chapman (1939) described it under the name Sudis squamosa, from the Gulf of Alaska south of the Alaska Peninsula. McAllister (1963a), in a revision of the Osmeridae, included all those nominal species of the Pacific in the synonymy of M. villosus. He included specimens from Arctic Canada in his study of Mallotus, which previously had not been included by authors, and con- cluded that the differences Schultz (1937) pointed out between Pacific and Atlantic populations were clinal, with the Arctic population falling in between, and did not recognize subspecies.
Recent studies on Mallotus have found a complex situation with several groups at species, subspecies, and population levels (e.g., Stergiou 1989, Dodson et al. 2007, Praebel et al. 2008). The combination of morphological characteristics with molecular genetic data warrant recognition of M. catervarius as a distinct species (Mecklenburg and Steinke 2015). In the study by Dodson et al. (2007), sequences from the Gulf of Alaska formed a separate clade, called the northeastern Pacific clade, from the Arctic clade, which included sequences from the northern Sea of Okhotsk, nor- thern Bering Sea, and Beaufort Sea, as well as one from Davis Strait off southeastern Baffin Island. In Mecklenburg and Steinke’s (2015) study, Gulf of Alaska sequences were identical to those from southern Kamchatka, the Bering, Chukchi, and Beaufort Seas, and Davis Strait.

duplicate closed flag here https://www.inaturalist.org/flags/460470

Can you please try to simplify/clarify what you are requesting here?

would you prefer:
a) we split Mallotus catervarius off from Mallotus villosus
or
b) we add ssp Mallotus villosus catervarius and Mallotus villosus villosus

if (a) what are the distributions for Mallotus catervarius and the narrowed Mallotus villosus

Reminder: upon review, WoRMS now accepts as valid species the Pacific capelan, Mallotus catervarius, separate from Mallotus villosus. http://www.marinespecies.org/aphia.php?p=taxdetails&id=301836

Distribution: North Pacific and adjacent Arctic. Here is a key reference by Mecklenburg et al. 2018: https://www.caff.is/monitoring-series/451-marine-fishes-of-the-arctic-region-vol-1

May I ask why this flag is not resolved to add the 2nd species, as is internationally recognized (FishBase, WoRMS, California Academy of Sciences, https://researcharchive.calacademy.org/research/ichthyology/catalog/fishcatmain.asp), in NE Pacific (Alaska to Washington).
