In this study, we report A. jasoni from Okinawa Trough, Japan, which represents the first record of this species and the genus from the Northwest Pacific. We determined 16S and 28S rRNA gene sequences from 1 of the 7 specimens collected. We compared our Northwest Pacific specimens to specimens from the Southwest Pacific, Atlantic, and Indian oceans, and our specimen was genetically most closely related to individuals from the Southwest Pacific.KeywordsAmphinomida, deep sea, Okinawa Trough, Polychaeta.Academic editor: Sergio N.

Check List 15 (3): 523–526. https://doi.org/10.15560/15.3.523IntroductionThe amphinomid annelid genus Archinome Kudenov, 1991 consists of 5 species, all of which are known from deep-sea hydrothermal vent and hydrocarbon seep areas (Borda et al. 2013). Members of the genus are distrib-uted worldwide, and 1 species, Archinome jasoni Borda et al., 2013, was originally described from hydrother-mal vents across the Atlantic, Indian, and the Southwest Pacific oceans (Borda et al. 2013). The species was orig-inally described by Borda et al. (2013) based on DNA sequence data.Our specimens of Archinome were collected from deep-sea hydrothermal vents in the Okinawa Trough, Northwest Pacific. Based on morphological and molecu-lar examinations, we identify the specimens as A. jasoni.MethodsWorms were collected by a suction sampler installed on the remotely operated vehicle (ROV) Hyper-Dol-phin on-board R/V NATSUSHIMA (cruise NT15-13) and ROV KAIKO (with vehicle Mk-IV) on-board R/V KAI-REI (cruises KR15-16 and KR15-17) from hydrothermal Check List 15 (3): 523–526 https://doi.org/10.15560/15.3.523315Copyright Jimi et al.

All sampling events were carried out under the Japanese law (no permit num-ber required). Live specimens were fixed in either 70% or 99.5% ethanol im mediately upon recovery of the sam-ples on the research vessel. Preserved specimens were observed with a Nikon SMZ1500 stereomicroscope and an Olympus BX51 compound microscope. All speci-mens (7 individuals) were deposited in Invertebrate Collection of Hokkaido University Museum (ICHUM). DNA extraction, PCR amplification, and sequencing of the 16S and 28S rRNA genes were carried out following the method of Jimi and Fujiwara (2016). Newly obtained sequences (determined from 1 specimen, ICHUM 5841) were deposited in the DNA Data Bank of Japan (DDBJ). A phylogenetic tree based on 16S sequences was con-structed based on maximum likelihood (ML) method by MEGA v. 7 (Kumar et al. 2016). The robustness of the ML tree was evaluated by 1000 bootstrap pseudo-rep-licates. In addition to newly obtained sequences, exist-ing 16S sequences for the phylogenetic analysis were obtained from GenBank (JX027999, JX028030–35, JX028038, JX028039, JX028047, JX028050, JX028051). Pairwise genetic distances were calculated on the basis of the 16S sequences using the uncorrected p-distance by MEGA v. 7. Species identification of the GenBank sequences follows Borda et al. (2013).ResultsOrder Amphinomida Lamarck, 1818Family Amphinomidae Lamarck, 1818Genus Archinome Kudenov, 1991Archinome jasoni Borda et al., 2013Figure 2New Japanese name: nessui-umikemushi,  ネッスイウミケムシArchinome jasoni Borda et al. 2013: 1–9, figs 2, 3.New records.

One median antenna present, arising from anterior part of caruncle, conical, very short. Caruncle narrow, elongated and trilobed, fused to body in chaetiger 2; posterior part of caruncle unat-tached. Segmental lobes large, laterally bursiform. Para-podia biramous; noto- and neuropodia well separated. Two dorsal cirri occur on notopodium and single ven-tral cirrus occurs on neuropodium, conical, whitish in ethanol. Branchiae present in chaetiger 3 and succeed-ing posterior chaetigers, branched from base. Noto- and neurochaetae bifurcate. Anus dorsally on one of poste-rior chaetigers. Pygidium with unpaired median cirrus. DDBJ LC46626 (16S, 447 bp, 1 sequence); LC466627 (28S, 832 bp, 1 sequence), determined from 1 of the specimens (ICHUM 5841).Morphological features and sequences of the present material are consistent with those given in the original description of A. jasoni in Borda et al. (2013).DiscussionIn the resulting tree based on 16S sequences, speci-mens from the Northwest Pacific and Southwest Pacific formed a clade (BS: 72 %) (Fig. 3). They differed by a mere 0–0.005% in terms of the uncorrected p-distance. The value is included in intraspecific variation of Archi-nome species (Borda et al. 2013). In 28S, the sequences did not show any intraspecific variation (data not shown). Archinome jasoni has been known previously from a wide range of localities across the Atlantic, Indian, and Southwest Pacific oceans (Borda et al. 2013). Our study represents the first record of the species and genus from the Northwest Pacific. Hutchings and Kupriyanova (2018) speculated that deep ocean currents are responsi-ble for moving larvae between ocean basins in deep-sea polychaete species showing a “cosmopolitan” distribu-tion. The genetic connectivity between the northwestern and southwestern Pacific populations of A. jasoni (Fig. 3) corroborates Hutchings and Kupriyanova’s (2018) speculation.Figure 3.

It also publishes scientiﬁc research ﬁndings and ofﬁcial reports relating to the polar regions in general, including the Arctic.  We welcome contributions not just from researchers but also from technologists involved in polar science or the Japanese Antarctic Research Expedition.2.　There are four types of submission.  When submitting a manuscript, please designate one of these types.a. Scientiﬁc paperResearch ﬁndings that are likely to contribute to the advance of polar science.b. Scientiﬁc notePreliminary research reports, new ideas, proposals, questions, case studies, etc. that are deemed worthy of being placed on record.c. Review articleSummary of previous studies and discussion of trends in research on a particular topic in polar science.d. ReportSelected reports on observations of the Japanese Antarctic Research Expedition, reports on the Japanese Antarctic Research Project and research projects in the Arctic, and reports on symposiums and meetings concerned with polar science that are deemed worthy of being placed on record.3.　The submitting author(s) should submit a manuscript prepared in accordance with the submission guidelines to the ofﬁce of the editorial committee through the online submission system.  The date of receipt is the date that the submission is completed.4.　When the submission is received, the author may be offered advice and guidance on the paper type, paper structure, problems with language, etc. by the editorial committee, which includes researchers in various ﬁelds of study (space and upper atmospheric sciences, meteorology and glaciology, geoscience, bioscience, and polar engineering).  Acceptance or rejection of manuscripts for publication and the order of publication are decided by the editorial committee.5.　After the submission is received, it is peer-reviewed and proofread by two referees in the case of a scientiﬁc paper, scientiﬁc note, or review article, or by one referee in the case of a report.  After the peer review, a ﬁnal manuscript revised according to the peer review and proofreading should be resubmitted to the ofﬁce through the online submission system.6.　The author is responsible for checking the ﬁrst proof.  Subsequent checks and copyediting will be carried out by the journal ofﬁce.  If it is known beforehand that the author will not be available, measures should be taken to avoid a delay in proofreading.7.　The copyright of published papers etc. belongs to our Institutions: Research Organization of Information and Systems, National Institute of Polar research.8.　Papers will be published with open access.  Ref:Open access https://www.budapestopenaccessinitiative.orgTechnical detailsLanguageThe ofﬁcial languages of Antarctic Record are Japanese and English.Preparation of the text(a) The manuscript should preferably be prepared on a word processor and printed with double spacing and wide margins and include an abstract of not more than 200 words.(b) Authors should use S.I. units.(c) The title page should include the name(s) of the author(s), their afﬁliations and addresses.  In cases of more than 50 letters for the title, authors should indicate a running title.(d) In case of a scientiﬁc note, the manuscript should be described within 15 pages (includes abstract, references, tables/illustrations, and so on).References(a) References in the text consist of the surname of the author(s), followed by the year of publication in parentheses.
