It can be easily distinguished from all known congeners by its lowest total vertebral count (76), dorsal- and anal-fin ray counts (71 and 54, respectively); unusual bluish coloration with blackish head; and the following additional features in combination: body fully scaled except the predorsal area but vertical fins completely scaleless; absence of oral valve, pseudobranchs and pyloric caeca; upper lip with pronounced flange; and periproct surrounded by peculiar tentacle-like processes. The new species is probably the smallest member of the genus, having developed testes at 98 mm standard length. Lycenchelys argentina, a rare and poorly-known species with a variable morphology, is herein redescribed based on a new (fourth known) specimen; we discuss the limits of its morphological variation. Lycenchelys cyanosoma sp. nov. and L. argentina may represent vicariant species with upper and lower bathyal\/abyssal range, respectively. The diagnostically valuable features and known distribution of all Antarctic and Subantarctic Lycenchelys species are presented.\n\u00a0<\/jats:p>","DOI":"10.11646\/zootaxa.5777.3.8","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T23:48:47Z","timestamp":1773877727000},"page":"540-554","source":"Crossref","is-referenced-by-count":0,"title":["A new dwarf species of Lycenchelys from western Antarctica with supplementary description of L. argentina (Teleostei, Zoarcidae)"],"prefix":"10.11646","volume":"5777","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2659-7469","authenticated-orcid":false,"given":"ARTEM M.","family":"PROKOFIEV","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0104-6436","authenticated-orcid":false,"given":"STANISLAV G.","family":"KOBYLIANSKY","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0877-2553","authenticated-orcid":false,"given":"ALEXEI M.","family":"ORLOV","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4913","published-online":{"date-parts":[[2026,3,19]]},"container-title":["Zootaxa"],"original-title":[],"link":[{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5777.3.8\/58563","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/mapress.com\/zt\/article\/download\/zootaxa.5777.3.8\/58563","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T23:48:48Z","timestamp":1773877728000},"score":1,"resource":{"primary":{"URL":"https:\/\/mapress.com\/zt\/article\/view\/zootaxa.5777.3.8"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,3,19]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,3,19]]}},"URL":"https:\/\/doi.org\/10.11646\/zootaxa.5777.3.8","relation":{},"ISSN":["1175-5334","1175-5326"],"issn-type":[{"value":"1175-5334","type":"electronic"},{"value":"1175-5326","type":"print"}],"subject":[],"published":{"date-parts":[[2026,3,19]]}}}
