During two cruises of the Federal Institute of Fisheries and Oceanography (VNIRO) in 2020 and 2021, commercial king crab stocks in the western part of the Bering Sea were surveyed, including 37 juvenile specimens of the golden king crab, <em>Lithodes aequispinus</em> Benedict, 1895, sampled at depths of 236–450 m. Two thirds of them were infested with a species of <em>Eremitione,</em> new to science. <em>Eremitione rybakovi</em> sp. nov. morphologically closely resembles <em>E. tuberculata</em>, but differs in having a relatively shorter pleon in females (0.3–0.4 of total body length), a slightly distorted body (0–20°), and more developed subrectangular dorsal extensions on the pereopodal bases; males of the new species have a more slender antennule with six articles (five articles in <em>E. tuberculata</em>).

In the present paper, we explore different trends in naming Kinorhyncha species over time to answer questions related to kinorhynch nomenclatural acts, compare trends among the different specialists and discuss possible suggestions for future species discoveries. We focus on detecting the main practices followed by the phylum specialists when coining new specific names, temporal trends in the used language and etymological basis for creating the names and differences between author preferences. It is interesting that not all Kinorhyncha names correspond to valid species, although the proportion of not accepted and uncertain names is low. On the other hand, the usage of classical languages (Latin and Greek) remains temporarily stable when coining species names, but other modern languages such as English, Spanish, Danish and Japanese are on the rise, partly due to the nationality of the current kinorhynchologists. Regarding the etymological basis, a replacement of traditional categories (morphology, geography) by eponyms has not been detected, even though the usage of the latter has significantly increased in recent years. Finally, since the creation of names is undoubtedly subjective, personal trends among the authors are obvious, each one following their own style and preferences.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"313 ","pages":"Pages 279-288"},"PeriodicalIF":1.2,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
