A poorly-known proboscidate leech species, Torix tukubana (Oka, 1935), in which the mid-body somites are biannulate dorsally and triannulate ventrally, is redescribed based on new specimens collected from its type locality, Mt. Tsukubasan in Honshu, Japan. The redescription provides the internal digestive and genital organs of T. tukubana for the first time. Our observation reveals that this species possesses equal-sized 1st–6th pairs of crop ceca that are nondiverticulated and tubular ovisacs running alongside the ventral nerve cord. Additionally, phylogenetic analyses using nuclear 18S rRNA, mitochondrial cytochrome c oxidase subunit I, 12S rRNA, tRNALeu, and NADH dehydrogenase subunit 1 markers reveal that T. tukubana is closely related to the Palearctic Hemiclepsis Vejdovský, 1884, in which the mid-body somites are triannulate.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":"133 1","pages":"59 - 71"},"PeriodicalIF":0.5,"publicationDate":"2020-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44589297","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new species of calliopiid amphipod, Calliopius ezoensis, from the eastern coasts of Hokkaido, Japan, is described and named. Calliopius ezoensis is similar to the North Atlantic C. sablensis Bousfield & Hendrycks, 1997, but can be discriminated from it in possessing two rows of calceoli on the peduncular articles of antennae 1 and 2 of the female, having a mandibular palp of article 3 longer than article 2, and setation of epimeral plate 3 on the ventral submargin. The new species is distinguished from North Pacific congeners by a combination of characteristics: in having dorsally smooth pereonites, the number of marginal and submarginal setal rows on epimeral plate 2, setation of palp article 2 of maxilla 1, indistinct sexually dimorphic gnathopods 1 and 2, and the length ratio of the inner and outer rami of uropod 2.

A new species of rhizocephalan barnacle is described parasitizing the Florida lobsterette Nephropsis aculeata Smith, 1881. This is the first record of a nephropoid as a host for any rhizocephalan and represents the first record of a rhizocephalan parasitizing any marine lobster (Achelata, Astacidea, Glypheidea, Polychelida). The new species belongs to the genus Parthenopea Kossmann, 1874, which now contains three species: Parthenopea australis Lützen, Glenner & Lörz, 2009 (on a callianassid in New Zealand), P. subterranea Kossmann, 1874 (on a callianassid and an axiid in the Skagerrak strait, Black Sea, and Mediterranean), and P. reinhardi n. sp. (on N. aculeata from Dry Tortugas, Florida, USA). The new species can be distinguished from the other two in the genus based on the shape of the seminal receptacle ducts (proximally straight in P. subterranea versus coiled in P. reinhardi n. sp.) and annuli on the stalk (present in in P. australis but absent in P. reinhardi n. sp.) and the position of the mantle opening (on the surface and close to the stalk in P. australis versus in a groove and more distant from the stalk in P. reinhardi n. sp.). We urge researchers and fisheries scientists working on marine lobsters to examine specimens for rhizocephalans, potentially leading to additional new records among lobster hosts.","PeriodicalId":54578,"journal":{"name":"Proceedings of the Biological Society of Washington","volume":"133 1","pages":"1 - 6"},"PeriodicalIF":0.5,"publicationDate":"2020-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43814444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
