Significant discrepancies between the first three of these specimens and Bergh's original description of D. ingolfiana are apparent, but they do not alter our opinion that all three specimens belong to a single, variable species. The monobasic taxon D. benthalis Barnard, 1963 is specifically distinct from D. ingolfiana. Bergh (1899) considered that the Doridoxidae had a holohepatic digestive gland (and thus was a member of the Anthobranchia). Our reassessments, particularly those concerning the structure of the digestive gland, branchial apparatus and anal site, indicate that Bergh misunderstood the form and polarities of these characters, and that the Doridoxidae must be relocated within the cladohepatic (i.e. actenidiacean) nudibranchs as its first offshoot. The Nudibranchia are thus divided into two major clades: Anthobranchia (= Bathydoridoidea + Doridoidea) and Dexiarchia nom. nov. (= Doridoxoidea + Dendronotoidea + Aeolidoidea + “Arminoidea”).","PeriodicalId":273031,"journal":{"name":"Zoologischer Anzeiger – A Journal of Comparative Zoology","volume":"2007 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125577240","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}

{"title":"Cambrian Derivatives of the Early Arthropod Stem Lineage, Pentastomids, Tardigrades and Lobopodians An ‘Orsten’ Perspective","authors":"A. Maas, D. Waloszek","doi":"10.1078/0044-5231-00053","DOIUrl":"https://doi.org/10.1078/0044-5231-00053","url":null,"abstract":"Abstract ‘Orsten’-type preservation is the phosphatisation of cuticular surfaces without any further deformation and has yielded completely three-dimensional fossils, mainly arthropods at scale of 100 μm—2 mm. Records of such exceptional fossils are now reported from several continents and from the Early Cambrian (approx. 520 Mi. years BC) to the Early Cretaceous (approx. 100 Mi. years BC). ‘Orsten’-type konservat - Lagerstatten from the Middle and Upper Cambrian have brought up mainly crustaceans and representatives of the Euarthropoda, but also derivatives of their early stem lineage. These are larval stages of Upper Cambrian pentastomids, tongue worms, which today are parasites of various tetrapods. A Middle Cambrian representative of the minute tardigrades is currently under description; it possibly represents the adelphotaxon of extant Tardigrada. New to science are fragments of a small tubular, finely annulated organism with similarly annulated segmental tubular limbs. This Upper Cambrian form, currently under investigation, may represent the first lobopodian in an ‘Orsten’-type preservation and expands their record to the late Cambrian. It shares with several of the Lower to Middle Cambrian Chengjiang and Burgess Shale fauna lobopodians the lobopodian design of its limbs, paired segmental dorsal outgrowths, and the finely annulated tubular body, which is smooth in the limb regions. New information presented by this ‘Orsten’ fossil concerns cuticular details undetectable on flattened fossils. Pentastomids, tardigrades and the onychophorans/lobopodians have been called “pro-” or “prot-arthropods” because they still lack, or partly lack, characteristic features known from later derivatives of the evolutionary line of Arthropoda. Among the three taxa, the Pentastomida are assumed to be the latest offshoot because they possess segmented limbs with pivoted joints between the articles. The now established record of all of the “pro-arthropods” and even true crustaceans in the earliest Palaeozoic implies, in our view, that the ancestry of Arthropoda lies even further back well in the Pre-Cambrian.","PeriodicalId":273031,"journal":{"name":"Zoologischer Anzeiger – A Journal of Comparative Zoology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120085218","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}

Although sometimes free-living, M. pedroana occurs most often inside the branchial chamber of B. occidentalis , and appears to be a commensal associate. It is not known from outside the range of the host along the Pacific coast of California and Mexico. Approximately 60% of hosts examined contained typically 1—2 M . pedroana in their branchial chambers, but many more (maximum 22) were sometimes found. M . pedroana showed no preference for host sex, size, or branchial chamber (left vs. right) and were not more abundant in any part of the distributional range. No M . pedroana were found on specimens of the five taxa mostly closely related to B . occidentalis . M . pedroana is re-described and its systematic position discussed with special reference to difficulties of generic placement. Although the presence of the bivalves causes physical deterioration to the hosts' gill filaments, available evidence indicates that the relationship is commensal, rather than parasitic.","PeriodicalId":273031,"journal":{"name":"Zoologischer Anzeiger – A Journal of Comparative Zoology","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124046644","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}

The cuticular structures called retinacula are described in detail and classified into various morphological types. The retinacula can be single or grouped in repeated patterns, or even united by a common base into a variety of complex structures. The surface of the individual retinaculum can be smooth or ornamented in various ways. The different types of retinacula intergrade to some extent and may all be derived from a single type, but they exhibit taxonomically informative differences. They are comparatively easy to study on traditional alcohol specimens and seem to offer the potential of an important suite of taxonomic characters which can be used also by non-specialists. It is recommended that all future species descriptions in the Rhizocephala use SEM to illustrate retinaculum morphology.","PeriodicalId":273031,"journal":{"name":"Zoologischer Anzeiger – A Journal of Comparative Zoology","volume":"1502 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127445029","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}
