Geodiversitas 43 (15): 405-573. https://doi.org/10.5252/geodiversitas2021v43a15. http://geodiversitas.com/43/15 ABSTRACT A revised taxonomy of Cenozoic radiolarian families is of particular importance because exhaustive molecu- lar phylogenetic analyses for Collodaria, Entactinaria, Nassellaria and Spumellaria have shown high level of confidence at family or higher taxonomic ranks. In this sense, this study presents a new comprehensive taxonomy at the family level that integrated a classification based on ribosomal taxonomic marker genes (rDNA) and classical morphological taxonomy. However, many family names commonly used in Cenozoic radiolarians (Polycystinea) are derived from genera whose type species were never illustrated at the time of KEY WORDS the generic definition. Obviously, in the vast majority of those cases, the “Principle of Typification” regulated Cenozoic, in the International Code of Zoological Nomenclature (ICZN 1999: Art. 61) cannot be logically applied. Radiolaria, This has contributed to a century-long misunderstanding about the validity of Cenozoic taxa (species, genera Molecular taxonomy, Morphological and/or family-group names) erected without any illustration or drawing of their types, in particular the huge taxonomy, contribution of Ernst Haeckel from samples of the Challenger expedition (1872-1876). Reexamination of Taxonomic revision, Haeckel’s collection definitively confirmed that all the original types series (the specimens on which Haeckel new synonyms, new status, established the nominal species-group taxon) being nonextant; in other words, all name-bearing specimens new families. (the types) are restricted to the illustrations given in Haeckel’s drawings. Because “types” in taxonomy are GEODIVERSITAS • 2021 • 43 (15) © Publications scientifiques du Muséum national d’Histoire naturelle, Paris. www.geodiversitas.com 405 Suzuki N. et al. precious things, a nominal species-group taxon lacking at all of illustration (or indication to a repository) do not ensure the recognition of the species. Following the rules and recommendations of the ICZN, these names should be excluded from all nomenclatorial and taxonomical acts. This revision presents the state of the art of all proposed family-group names (with full synonymy lists) for Cenozoic Polycystinea. The list of family-group nominal taxa and their names was inventoried from 6694 publications (89% of the whole known references on radiolarians). The references were examined in order to clarify and fix the status of family names; hence these family-group names were rigidly classified as: valid, junior synonym, nomen dubium, nomen nudum, homonym, and invalid names. A total of 372 family-group names were proposed for the Cenozoic. These consist of 94 valid family-groups, 118 junior synonym family-groups, 111 nomen dubium family-groups (mainly artificially created in a hypothetical conceptual framework), 6 junior homonym family-groups, 19 nomen nudum family-groups, as well as 24 invalid names. In addition, one nomen novum et four new families are presented. The description of 25 families have been also emended. This study also outlines the advantages of an integrated approach to taxonomy of Polycystinea by the combination of both morphological and molecular systematics. Based on molecular phylogenetic studies, the systematic classification proposed at suprageneric level is arranged as follows: a) Order Spumellaria: three Phylogenetic Molecular Lineages (PM Lineages = suborders), 13 su- perfamilies and 42 families; b) Order Entactinaria: one PM Lineage, five superfamilies and nine families; c) Order Nassellaria: four PM Lineages, 16 superfamilies and 37 families; d) Order Collodaria: three superfamilies and six families. RÉSUMÉ Une nouvelle classification systématique intégrée basée sur la phylogénèse moléculaire et le classement morphologique des radiolaires du Cénozoïque (Classe des Polycystinea) – taxonomie supragénérique et actes logiques de nomenclature. Une révision de la taxonomie des familles de radiolaires du Cénozoïque est particulièrement importante, car de nouvelles analyses phylogénétiques moléculaires pour Collodaria, Entactinaria, Nassellaria et Spu- mellaria ont montré d’excellents résultats pour les rangs taxonomiques familiaux ou supérieurs. En ce sens, cette étude présente une nouvelle taxonomie complète au niveau familial, qui intègre une classification fondée sur les gènes marqueurs taxonomiques ribosomiques (ADNr) et la taxonomie classique fondée sur des caractéristiques morphologiques. De plus, de nombreux noms de familles communément utilisés pour les radiolaires polycystines du Cénozoïque dérivent de genres dont les espèces types n’ont jamais été illustrées au moment de la définition du genre. Apparemment, dans la plupart de ces cas, le « Principe de Typification » défini dans le Code international de Nomenclature zoologique (ICZN 1999: Art. 61) ne peut être logiquement utilisé. Cela a généré une longue incompréhension (un siècle) quant à la validité des taxa cénozoïques (noms d’espèces, genres, et/ou familles) érigés à partir de types non illustrés ou dessinés, en particulier dans l’immense travail de Ernst Haeckel sur les échantillons récoltés par l’Expédition du « Challenger » (1872-1876). Le réexamen de la collection d’Haeckel a définitivement confirmé que tous les originaux des espèces types d’Haeckel (les spécimens à partir desquels Haeckel a établi les taxa des groupes d’espèces) n’existent pas, en d’autres termes que les spécimen-types sont réduits aux illustrations des planches dessinées

RADIOLARIANS FROM LEG 134, VANUATU REGION, SOUTHWESTERN TROPICAL PACIFIC1 Amy L. Weinheimer,2 Annika Sanfilippo,2 and W.R. Riedel2 ABSTRACT In the cores obtained during Leg 134 of the Ocean Drilling Program, radiolarians occur intermittently and usually in a poor state of preservation, apparently as a result of the region having been at or near the boundary between the equatorial current system and the south-central Pacific water mass during most of the Cenozoic. A few well-preserved assemblages provide a record of the Quaternary forms, and some displaced middle and lower Eocene clasts preserve a record of radiolarians near that subepochal boundary. There are less satisfactory records of middle Miocene and early Miocene to late Oligocene forms.

PDMPO is accumulated with silica under acidic con- ditions, and the newly developed silica skeletons show green fluorescent light. This study is the first to use PDMPO in polycystine radiolarians, which are unicellular planktonic protists. We tested Acanthodesmia sp., Rhizosphaera trigo- nacantha, and Spirocyrtis scalaris for emission of green fluorescence. Entire skeletons of Acanthodesmia sp. and Sr. scalaris emitted green fluorescent light, whereas only the outermost shell and radial spines of Rz. trigonacantha showed fluorescence. Two additional species, Spongaster tetras tetras and Rhopalastrum elegans did not show fluorescence. Green fluorescence of the entire skeleton is more like the “skeletal thickening growth” defined by silica deposition throughout the surface of the existing skeleton. The brightness of the fluorescence varied with each cell. This difference in fluorescence may reflect the rate of growth in these cells. Green fluorescence in PDMPO-treated polycystines sug- gests the presence of similar metabolic systems with controlled pH.

Previous work has divided eukaryotic diversity into a small number of high-level ‘supergroups’, many of which receive strong support in phylogenomic analyses. However, the abundance of data in phylogenomic analyses can lead to highly supported but incorrect relationships due to systematic phylogenetic error. Further, the paucity of major eukaryotic lineages (19 or fewer) included in these genomic studies may exaggerate systematic error and reduces power to evaluate hypotheses.

La Subclase Radiolaria está formada por 2 superórdenes: Trypilea y Polycystina, siendo el último el más estudiado, pues su esqueleto de opal es más resistente a la disolución en agua de mar y por ende, más comúnmente preservados en el registro fósil. Los radiolarios han sido usados como una útil herramienta oceanográfica, bioestratigráfica y paleoambiental, gracias a su esqueleto de sílice y a su gran rango geológico. En nuestro país el conocimiento de este grupo es muy escaso, es por esto que el presente trabajo, tiene como principal objetivo, aportar con la identificación y descripción de especies de radiolarios Polycystinos, no antes registrados para esta zona en particular.

Żwirki i Wigury 93, 02-089 Warszawa, Poland Pszczółkowski. A., 1989. Late Paleozoic fossils from pebbles in the San Cayetano Formation, Siena del Rosario. Cuba. Ann. Soc. Geol. Polon.. 59: 27 40. Abstract: Late Paleozoic Foraminiferida and Bryozoa have been found in silicified limestone pebbles collected from the sandstones of the San Cayetano Formation in the Sierra del Rosario (western Cuba). All but one specimen of Foraminiferida belong to the Fusulinaeea and include Schwagerina sp. and Parafusulina sp. One specimen of Tetrataxis sp. has been found together with the bryozoan Rhabdomeson sp. The schwagerinids are of Permian (probably Leonardian) age, and the other fossils are of Carboniferous or Permian age. The fossiliferous pebbles were derived from Late Paleozoic rocks located at least some hundred kilometers from the San Cayetano basin during Middle Jurassic to Oxfordian time. The schwagerinid-bearing pebble of Permian age could have been transported from Central America, southwestern North America or northwestern South America (?). Key words: Foraminiferida, Late Paleozoic, Middle-Upper Jurassic, Cuba. Manuscript received February 17, 1988, accepted April 26, 1988 INTRODUCTION In the present paper the first occurrence of Late Paleozoic fossils in Cuba is reported. These fossils were found in pebbles collected from the San Cayetano Formation (Middle Jurassic-Middle Oxfordian) of the Sierra del Rosario in western Cuba (Fig. 1). Besides the characteristics of fossils, this study also deals with the problem of provenance of the fossil-bearing pebbles.

Characteristic schwagerinid species in this area are Paraschwagerina magna Skinner and Wilde, Schwagerina hawkinsiformis Igo, Chalaro schwagerina kalmykovae Davy do v, and Pseudofusulina duplithecata Igo. These and some other species in and around this area are common to and deeply connected faunistically with those of the Mino Tamba Terrane and some Circum-Pacific terranes including Nadanhada, Sikhote-Alin, Koryak, Oregon, and California. They are completely absent in the Permian Akiyoshi Terrane. Foraminiferal faunal similarities between Jurassic terranes of Japan and these Circum-Pacific terranes are important paleogeographically and technically, and strongly suggest the dispersal of these terranes from the Panthalassan domain. Key words: Early Permian fusulinaceans, exotic blocks, Hanagiri Shimokuzu area, faunal affinity, Panthalassan domain Introduction On the basis of faunal analysis, this paper pointed out that Early Permian fusulinaceans in and In the eastern part of the Kanto Mountains, around the Hanagiri-Shimokuzu area are similar to Jurassic accretionary complexes are widely those of the Mino-Tamba Terrane of Japan and distributed in both northern and southern sides of some Circum-Pacific terranes (Nadanhada, Sikhote- the Mikabu ophioilitic rocks of the Sambagawa Alin, Koryak, Oregon, and California), and Terrane (Figure 1).
