Paralomis okitoriensis is a species of king crab.{{cite journal|url=https://www.kahaku.go.jp/research/publication/zoology/download/45_1/L_BNMNS_45-1_23.pdf|last=Takeda|first=Masatsune|title=A New Crab-shaped Anomura of the Genus Paralomis White, 1856 (Crustacea, Decapoda) from the depths off Okino-Torishima, Southernmost Island in Japan|journal=Bulletin of the National Museum of Natural Sciences, Series A|volume=45|issue=1|pages=23–30|date=22 February 2019|archive-url=https://web.archive.org/web/20220122233449/https://www.kahaku.go.jp/research/publication/zoology/download/45_1/L_BNMNS_45-1_23.pdf|archive-date=22 January 2022|url-status=live|access-date=4 September 2023}} It has been identified near Japan's southernmost atoll, Okinotorishima.
Appearance
P. okitoriensis is orange-red in colour with a pyriform carapace covered symmetrically in sharp tubercles on its dorsal surface. The carapace's edges, by contrast, feature sharp spines. The female holotype's carapace measures {{Convert|44.2|mm|in|abbr=on}} long and {{Convert|43.5|mm|in|abbr=on}} wide. Its chelipeds bear a mix of longer spines on the inner side and smaller ones on the outer side; the chelipeds, including the chelae, are "remarkably slender". The palms of its chelae are armed with spine-like tubercles tipped with tufts of setae, and its fingers are untoothed and heavily bristled. Its walking legs – also slender – are especially spinose. On its underside, its abdominal segments are well-developed; some are armed with tubercles, while others are smooth.
Distribution
P. okitoriensis is known from only one female holotype found in January 2006 off Japan's southernmost atoll, Okinotorishima, at a depth somewhere between {{Convert|900 and 1500|m|ft|abbr=on}}. It was the 12th species of Paralomis described from Japanese waters.
Taxonomy
P. okitoriensis was described in 2019 by carcinologist Masatsune Takeda. Its name is a combination of the Japanese shorthand {{Lang|ja-latn|Oki-Tori}} for the Okinotorishima atoll where the holotype was found and the Latin suffix -ēnsis indicating {{Gloss|of or from a place}}.{{efn|Lit. "Of/from Okinotorishima"}} It falls into an informal subgroup of Paralomis described by carcinologist Shane T. Ahyong which includes P. aculeata and P. spinosissima; this subgroup is characterized by its long chelipeds and walking legs as well as short, well-spaced tubercles on its carapace.{{Cite book|last=Ahyong|first=Shane T.|author-link=Shane T.
