A detailed comparison between M. heterodon and its only congener, M. grandoculis (Forsskål, 1775), from which it has previously been distinguished primarily by scale rows below the lateral line and fresh or live coloration, revealed new diagnostic characters, most of which are applicable to preserved specimens. In addition to previously recognized characters, the two species can be distinguished by mid-dorsal snout profile in adults (concave vs. straight), snout length (excluding lips) [8.9–11.1 (mean 9.9) % of SL vs. 10.3–12.1 (11.2) % SL], spinous anal-fin base length [4.6–5.9 (5.0) % of SL vs. 3.9–4.9 (4.4) % SL], a distinct black blotch above the pupil (absent vs. present), a dark brown stripe across the post interorbital region in preserved specimens (present vs. absent), and preserved coloration of the pectoral-fin base inner surface (blackish brown vs. light brown).","PeriodicalId":37692,"journal":{"name":"Species Diversity","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46517988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These three nominal species are the type species of the genus-group names Lineus Sowerby, 1806, Borlasia Oken, 1815, and Nemertes Cuver, 1816, respectively, which are in turn the type genera of the family-group names Lineidae McIntosh, 1874, Borlasiidae Diesing, 1862, and Nemertidae Ehrenberg, 1831. Therefore, Lineus Sowerby, 1806 (currently in use) is a senior subjective synonym of Borlasia Oken, 1815 and Nemertes Cuvier, 1816 (both currently not in use), while Lineidae McIntosh, 1874 (currently in use) is a junior subjective synonym of Borlasiidae Diesing, 1862 and Nemertidae Ehrenberg, 1831 (both currently not in use); in addition, Micruridae Ehrenberg, 1831 (not in use) is also a senior synonym of Lineidae McIntosh, 1874.

In this study, the diagnostic characters between M. gymnopterus and M. hattae Jordan and Snyder, 1901 are provided, based on our morphological observations of 37 specimens, including Okinawan specimen, and previous studies, as follows: head length [ M. gymnopterus 11.8– 15.0% of total length (TL) vs. M. hattae 9.4–11.0%], trunk length (24–25.4% of TL vs. 28–31%), the horizontal distance from the dorsal-fin origin to a vertical line through the anus 73–87% of head length vs. 13–49%), the number of vertebrae (total 129–130 vs. 148–155; predorsal 30 vs. 47–53; preanal 41–44 vs. 51–55), the number of the lateral-line pores before the anus (43–45 vs. 51–55). Additionally, the body depth at the gill opening in TL and the trunk length in TL can also be used to distinguish between these two species (2.8–3.7% of TL vs. 1.4–3.0%).

Since the original description of A. caecus was insufficient, this paper reports on the morphology of the species based on a detailed examination of the female. In particular, the first and second antennae, the first and second maxillae, and four pairs of legs, whose features were poorly known, are reported in detail. The specimen of A. caecus is inferred to have detached itself and moved from a fish host, perhaps a coastal puffer, to the squid while these two animals were trapped in the net or when they were removed from the net. Following Argulus scutiformis Thiele, 1900, A. caecus is the second species of Argulus found from northern Japan located in the northern temperate or subarctic region, and its occurrence in this region is likely to be affected by the Tsushima Warm Current and its branch, the Tsugaru Warm Current, both of which flow off the coast of the region.","PeriodicalId":37692,"journal":{"name":"Species Diversity","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44772642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
