INVALID NAME. ��� Coccymelium. NOMINA DUBIA. ��� Conophacodiscus, Pentadiscus, Triadiscus. DIAGNOSIS. ��� Shell roughly flat, consists of a large convex lensshaped latticed shell. Radial beams arise from the outer medullary shell and radiate to both sides of the equatorial plane. These beams are connected to the large latticed shell. Exterior structure outside of the large latticed shell absent or exclusively represented by a simple solid flat circular edge which is surrounded by distinctive solid arrowhead-like short spines. No structure extends to both sides of the equatorial plane. STRATIGRAPHIC OCCURRENCE. ��� Early Eocene-Living. REMARKS Phacodiscus shares a homeomorphous appearance to Heliodiscus representatives without spines. The latter genus is a living form and has a characteristic microsphere, always eccentrically placed in the second inner shell (outer double medullary shell). The Phacodiscidae are an extinct family, whereas Heliodiscidae is a common component of living plankton. Periphaena has a special distinguishable pore near its center on one side of the cortical shell, probably an exit for the axoflagellum (Sugiyama & Furutani 1992: pl. 16, fig. 6). The internal skeletal structure of Periphaena has been illustrated (Sugiyama & Furutani 1992: pl. 16, fig. 5). VALIDITY OF GENERA Phacodiscus The same type species was designated for the following combinations of genera: Phacodiscus and Phacodiscinus; and Prunulum, Prunuletta and Coccymelium. Haeckel (1887) seems to propose new taxon name for differently oriented specimens in some cases. Sethodiscinus is considered to have a simple medullary shell (Campbell 1954: D78), but the innermost shell is known to be easily dissolved. Phacodiscus is validated due to the oldest available name among them. The type image for Phacodiscus is poor (Haeckel 1887: pl. 35, fig. 7) but it is unfortunately ��� Phacodiscus ��� can be precisely identified by using this poor image., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on page 424, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["HAECKEL E. 1882. - Entwurf eines Radiolarien-Systems auf Grund von Studien der Challenger-Radiolarien.

INCLUDED GENERA. ��� Collophidium Haeckel, 1887: 26. NOMEN DUBIUM. ��� Colloprunum. DIAGNOSIS. ��� Collophidiidae are Colonial Collodaria with a variable elongated, cylindrical, or spherical appearance. Each colony is comprised of a delicate gelatinous material that encompasses the scattered algal symbionts and the string-like aggregations. A stringlike aggregation includes tens to a hundred collodarian cells within a firm gelatinous material. The central capsule is of an elongated cylindrical shape, with an endoplasm highly vacuolated. STRATIGRAPHIC OCCURRENCE. ��� Living. REMARKS The taxonomic independency of Collophidium was initially recognized by the studies of Anderson et al. (1999). This was achieved by the observation of ultrafine cellular structure and the publication of ���living��� images.Their results were later supported by a molecular phylogenetic study by Ishitani et al. (2012). The microbial eukaryotes (0.8-20 ��m) of the bathypelagic zone (3000-4000 m in water depth) in global oceans are dominated by Collophidium, suggesting the important role of this genus in the deep-ocean (Pernice et al. 2016). This family can be easily distinguished from the other collodarian families by the presence of cell-embedded sacks observed within the gelatinous matter. Many undescribed genera and species are encountered in plankton samples. Four Collophidium species were drawn in figs 10-13 of Strelkov & Reshetnyak (1971) but need to be described again as new species due to their identification based on the unillustrated species of Haeckel (1887)., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on pages 527-528, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["BIARD T., PILLET L., DECELLE J., POIRIER C., SUZUKI N. & NOT F. 2015. - Towards an Integrative Morpho-molecular Classification of the Collodaria (Polycystinea, Radiolaria).

Collosphaeroidea ��� Bertolini 1937: 1268. DIAGNOSIS. ���For Colonial Collodaria, the colony consists of many collodarian cells which are embedded in a gelatinous support. A reticulated system of pseudopodia interconnects the collodarian cells inside the gelatinous substance. The cell is constituted of three zonal structure: the adipose droplet (oil droplet) in the center, the intracapsular zone with an endoplasm, and the extracapsular zone with ectoplasm. The intracapsular zone includes many small nuclei, pigmented spherules observed in light microscopy, and several small orthorhombic shaped crystals. The intracapsular zone is bounded from the extracapsular zone by the capsular wall. The extracapsular zone resembles a transparent clear thin zone and consists of the ectoplasm and pseudopodia. Anatomically, the pseudopodia are part of the endoplasm. The endoplasm extrudes from the intracapsular zone through the fusules, that is a special tunnel organelle on the central capsule. The extracapsular zone is bounded by the plasmalemma of the gelatinous material. The pseudopodia buried in gelatinous material radiate and appear as fibers of gelatinous matter. The algal symbionts are located in the ectoplasm or in the gelatinous matter. The boundary of the gelatinous matter is unknown. If present, the siliceous skeletons are wrapped with silicalemma. It is unknown whether the silicalemma is a part of the endoplasm and/or of the ectoplasm. REMARKS The Collodaria are conventionally divided into ���colonial Collodaria ��� and ���solitary Collodaria ���; the former is commonly known as Sphaerozoidea. One of the most comprehensive studies of the Sphaerozoidea was performed by Strelkov & Reshetnyak (1971). The morphological terminology adopted in fig. 6 of Strelkov & Reshetnyak (1971) is a basis in understanding the Sphaerozoidea. The metabarcoding survey found that the coastal area populations are dominated by the Sphaerozoidae, while open ocean populations are dominated by the Collosphaeridae (Biard et al. 2017). Although the exact taxonomy of the host is unknown, amphipod species such as Oxycephalusclausi, Streetsiaporcella and Hyperietta stebbingi were found among Sphaerozoidea (Harbison et al. 1977; Zeidler 2016). The Sphaerozoidea consists of the Collophiidae, Collosphaeridae and Sphaerozoidae. The formation of superfamily names for this group needs some additional explanations. The Latin stem of Sphaerozoum is Sphaerozo-, thus Sphaerozo-oidea is grammatically correct. However, in this case, there is an old pronunciation problem. When one pronounces a double ���oo���, the result is not very nice for Latin, Italian, French and Spanish ears. In English the pronunciation can result as ���ouuu��� sound. There is just a big exception which is the Greek name ���zoon��� = zoo (identical in all European languages, even in Russian). The prevalent use in occidental languages is to remove the additional ���o���, so as not to pronounce this not phonetically nice ���oo���. Sphaerozoidae sounds better than Sphaerozooidae.Very often, many radiolarists have been using translations of such word in their native languages: Sphaerozoid��s in French, Sphaerozoids in English and Sphaerozoiden in German (always without a double ���o���)., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on page 527, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["MULLER J. 1859 a. - Uber die Thalassicollen, Polycystinen und Acanthometren des Mittelmeeres.

DIAGNOSIS. ��� Thalassosphaeridae consist of solitary Collodaria. The protoplasm consists of a single central large nucleus surrounded by an endoplasm. A very high number of isolated siliceous spicules are scattered outside the endoplasm. STRATIGRAPHIC OCCURRENCE. ��� Living. REMARKS No molecular data was obtained but the Thalassosphaeridae are suspected to be one of the different living stages of Thalassicollidae (see remarks for Thalassicollidae). This family includes the first described polycystine genus in history, namely Physematium, but the original images in Meyen (1834) are too ambiguous, making it difficult to determine real specimens without a dose of interpretative imagination. However, the ecology of Physematium has been studied in wide area of open oceans. In this sense, there are several studies on the functional morphology of the colony (Anderson et al. 1986b), the trophic activity (Swanberg & Anderson 1985; Swanberg et al. 1986a), as well as their feeding preferences (Swanberg et al. 1986b). ���Living��� images were illustrated for Lampoxanthura (Anderson 1983: figs 1.2.C-1.2.D), Thalassosphaera (Suzuki & Aita 2011: fig. 5E; Suzuki & Not 2015: fig. 8.13.2), ��� Physematium ��� (Anderson 1983: figs.1.2.A-1.2.B; Anderson et al. 1986b: figs 1.1-1.2) and ��� Thalassoxanthium ��� (Hollande & Enjumet 1953: fig. 18). However, these ���living images��� were obtained for nomina dubia genera such as ��� Physematium ��� and ��� Thalassoxanthium ���. Many undescribed ���genera��� of Thalassicollidae are also commonly found in plankton samples., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on pages 533-534, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["HAECKEL E. 1862. - Die Radiolarien (Rhizopoda Radiaria).

Order ENTACTINARIA Kozur & Mostler, 1982 Molecular phylogenetic lineage III (Sandin et al. 2021) DIAGNOSIS. ��� One, to rarely two or three, spherical cortical shells, whose wall are made of a spongy layer or of a spherical shape consisting of a full coarse mesh. The central cubic structure is framed with sharp corners and contains a heteropolar microsphere; with MB and two A-rays on its top. Following an author���s recommen- dation (PD), the Lineage III is regarded as a living Entactinaria. Nonetheless, it is noted that the true genus Entactinia have a MB and two sets of radial rays at both ends; however, it has never been observed in living Entactinaria (Nakamura et al. 2020: supplement). REMARKS We include the Rhizosphaeroidea (Clade G: Haliommilla, Rhizosphaera), Centrocuboidea (Clade H: Octodendron; Clade I: Plegmosphaeromma), Centrolonchoidea, Heliosaturnaloidea and Thalassothamnoidea in the Entactinaria sensu Dumitrica, but the diagnosis for the Lineage III shown above does not include Centrolonchoidea, Heliosaturnaloidea and Thalassothamnoidea due to the lack of molecular support. The axopodial system was regarded as a determinant character applicable to superfamily or order level taxonomy (Hollande & Enjumet 1960; Cachon & Cachon 1985). However, molecular phylogenetic studies (Sandin et al. 2021) discarded this hypothesis., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on page 461, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["KOZUR H. & MOSTLER H. 1982. - Entactinaria subordo Nov., a new radiolarian suborder.

REMARKS The internal skeletal structure of Pentapylonium was already illustrated (Dumitrica 1991: pl. 5, figs 1-9; pl. 6, figs 1-9; pl. 7, figs 1-7). As reporting of Pentapylonium implicatum is limited to the upwelling regions off Peru, Oman and Somali (Nigrini & Caulet 1992), this family can rarely be observed in other regions. The overall appearance of Sphaeropylolena (Pylodiscidae) is similar to that of Pentapylonium, but the former fundamentally differs from the latter by the presence of a pylodiscid center (Zhang & Suzuki 2017: 38)., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on page 456, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["DE WEVER P., DUMITRICA P., CAULET J.

INCLUDED GENERA. ��� Bekoma Riedel & Sanfilippo, 1971: 1592. ��� Bekomiforma Sanfilippo & Riedel, 1974: 1020. ��� Lamprotripus Haeckel, 1882: 431. ��� Orbula Foreman, 1973a: 437. NOMINA DUBIA. ��� Stichocampe, Stichopterium. DIAGNOSIS. ��� Bekomidae consist of two-segmented Lithochytridoidea (exclusive of Orbula) with six collar pores that form the basal ring of the cephalis, two free A- and V-rods in the cephalic cavity, and three feet. Except in the case of Lamprotripus, the cephalis is covered with a thick siliceous wall. The cephalic initial spicular system consists of A-, V-, D-, double l-, and double L-rods. A combination of A- and V-rods, or solely A-rod, forms one or more significant cylindrical apical horn(s). D- and double L-rods protrude from the cephalis and form three feet or rims on the thorax. The MB is located in the center of the basal aperture of the cephalis. The basal ring is directly connected to the D-, double l- and double L-rods. The basal ring tends to be located horizontally in the cephalic cavity. Although the basal ring is generally merged to the shell wall, it is well visible in older forms (Bekoma and Bekomiforma) but degraded in a younger form (Lamprotripus). A protoplasm is observed in Lamprotripus. The endoplasm is opaque dark grey, filling the upper part of the shell at the level where three rod wings are separated from the shell. No algal symbionts are present. STRATIGRAPHIC OCCURRENCE. ��� Middle Paleocene-Living. REMARKS The Bekomidae are distinguishable from the Lithochytrididae. The latter lack the double l-rod and have four collar pores instead of six and their MB is oblique to the collar stricture.The cephalic initial spicular system was illustrated for Bekoma (Nishimura 1992: pl. 5, figs 4, 5, 9, 11; pl. 8, fig. 5?), Bekomiforma (Sugiyama et al. 1992: pl. 20, fig. 1) and Lamprotripus (Nishimura & Yamauchi 1984: pl. 31, fig.1; Nishimura 1990: figs 26.6, 26.7, 29.6; Sugiyama et al. 1992: pl. 22, fig. 1). The diagnosis written above excludes the characteristics of ��� Lamprotripus ��� mawsoni (Riedel 1958). As this species lacks the double l- and V-rods (Sugiyama et al. 1992: pl. 16, figs 4, 5), it cannot be placed in Lamprotripus. This species is also grouped with Dictyopodium (= Pterocanium in original) but not Lamprotripus in the Clade I (Sandin et al. 2019). ��� L.��� mawsoni has three collar pores as opposed to four.Sugiyama et al. (1992: 18-19) conceptualized it as a new genus.

NOMEN DUBIUM. ��� Spongioconcha. DIAGNOSIS. ��� Thick spongy spherical cortical skeleton with a single or double medullary shell and a variable number of threebladed radial spines. Protoplasm is well observed in Spongosphaera. Endoplasm of brownish gray color, filling a spongy shell. Dark brownish red to reddish brown granular pigments surround the surface of the endoplasm. Axopodia radiate throughout the endoplasm. Algal symbionts are scattered on the endoplasm. Axopodial system of centroaxoplastidtype: the Axoplast is a very small fused point, located within the inner microsphere (inner double medullary shell). Nucleus is located inside the outer medullary shell or is found wrapping it. Significant bundles of axoneme are not present. Instead of bundles, axoneme radiate evenly throughout the intracapsular zone. STRATIGRAPHIC OCCURRENCE. ��� early Middle Miocene-Living. REMARKS The genus Spongosphaera is characterized by a double medullary shell and straight three-bladed radial spines. We place the genera Diplospongus and Spongodendron into Spongosphaeridae based on the presence of three-bladed radial spines, although both genera seem to have a single medullary shell. As Spongosphaera streptacantha is typically found in plankton samples from tropical to subtropical oceans, many observations were related as well as personally observed. S. streptacantha is the only Spumellaria whose images can be captured in the ocean with an autonomous visual plankton recorder (A-VPR) (Nakamura et al. 2017: fig. 2.C). Thus, its taxonomic stability and oceanographic response are important. The number of radial beams of this species is varies from six to twelve, its internal structure was also illustrated in detail (Kurihara & Matsuoka 2004). By referring to this case, other genera belonging to Spongosphaeridae presumably have significant variations. The fine protoplasmic structure was illustrated in Diplospongus (Hollande & Enjumet 1960: pl. 6, figs 4-9), Spongodendron (Hollande & Enjumet 1960: pl. 6, figs 1-3; pl. 7, fig. 5) and Spongosphaera (Hollande & Enjumet 1960: pl. 9, figs 8-10; pl. 22, figs 8, 9; pl. 23, figs 1, 2; pl. 24, fig. 2; pl. 26, fig. 4). An image of living forms was illustrated for Spongosphaera (Cachon et al. 1989: fig. 1; Matsuoka 2007: fig. 5.a; 2017: figs 6.1, 6.2; Matsuoka et al. 2017: appendix A). According to Cachon (1964), ��� Spongosphaera ��� is infected with Hollandella myceloides, but it is impossible to amend the taxonomic name for the host without having a more complete image. Spongosphaera streptacantha can exceptionally survive in high temperatures (> 30��C) in the Malacca Strait (Zhang et al. 2020) and is also regularly found in 17.1-19.4��C in the Japan Sea (Kurihara & Matsuoka 2010). This is the only one species with this very wide range of survival sea water temperature. VALIDITY OF GENERA Spongosphaera Morphological variation of Spongosphaera was well illustrated in many previous studies (Kurihara & Matsuoka 2004; van de Paverd 1995: pl. 28, figs 2, 5-7). Hexadoridium is characterized by two concentric medullary lattice shells and a spongy octahedral shell (Campbell 1954: D60). As the specimen identifiable as Hexadoridium streptacanthum is regarded as Spongosphaera polyacantha form streptacantha by van de Paverd (1995: pl. 2, fig. 2), Hexadorium is a synonym of Spongosphaera. Spongosphaeromma is characterized by two medullary lattice shells surrounded by a cortical shell bearing many radial spines (Campbell 1954: D68). Nishimura & Yamauchi (1984: 33) seems to be the first paper to illustrate the type species Spongosphaeromma as ��� Spongosphaera helioides ��� and this morphological character fits with not only the definition of Spongosphaeromma but also the variation in Spongosphaera. Spongosphaera is the oldest available name among them., Published as part of Suzuki, Noritoshi, Caulet, Jean-Pierre & Dumitrica, Paulian, 2021, A new integrated morpho- and molecular systematic classification of Cenozoic radiolarians (Class Polycystinea) - suprageneric taxonomy and logical nomenclatorial acts, pp. 405-573 in Geodiversitas 43 (15) on pages 418-419, DOI: 10.5252/geodiversitas2021v43a15, http://zenodo.org/record/5101757, {"references":["HAECKEL E. 1862. - Die Radiolarien (Rhizopoda Radiaria).

The plankton radiolarian community was investigated in the spring season during the two-month cruise &lsquo, Shiyan1&lsquo, (10 April&ndash, 13 May 2014) in the Eastern Indian Ocean. This is the first comprehensive plankton tow study to be carried out from 44 sampling stations across the entire area (80.00&deg, &ndash, 96.10&deg, E, 10.08&deg, N&ndash, 6.00&deg, S) of the Eastern Indian Ocean. The plankton tow samples were collected from a vertical haul from a depth 200 m to the surface. During the cruise, conductivity&ndash, temperature&ndash, depth (CTD) measurements were taken of temperature, salinity and chlorophyll a from the surface to 200 m depth. Shannon&ndash, Wiener&rsquo, s diversity index (H&rsquo, ) and the dominance index (Y) were used to analyze community structure. There was a total of 168 plankton species, composed of Acantharia, Phaeodaria, Polycystina, Collodaria and Taxopodida (monospecific&mdash, Sticholonche zanclea, Hertwig is the only recognized species). Hence, it included both celestine-based and siliceous organisms, which are also described here for the first time from this region. Total radiolarians ranged from 5 to 5500 ind/m&minus, 3, dominated by co-occurrences of Sphaerozoum punctatum and Stichonche zanclea species at the south-equator zone (SEQ)-transect 80&deg, E and equator zone (EQ)-transect Lati-0. The possible environmental variables were tested through RDA analysis, although no result was obtained for the full species dataset, the samples from the equatorial transect related strongly to mixed-layer chlorophyll a concentration and those of a north&ndash, south transect to surface silicate concentrations or mixed-layer nitrate were significantly correlated (p &lt, 0.01) to the radiolarian community. Our results indicate that the silicate and chlorophyll-a concentrations are the two major factors affecting the radiolarian distribution along two of the investigated transects (southern equator and equator) in the study area.

Siliceous planktonic species of the phyla Retaria and Cercozoa were investigated from the surface to a 200 m depth around the eastern Indian Ocean (80.00°–96.10° E, 10.08° N–6.00° S) during a 2-month cruise (10 April–13 May 2014). These species are commonly referred to as Radiolarians and are found in all of the world’s oceans, however, this is a detailed investigation of the species’ diversity in the eastern Indian Ocean. Samples were collected from the eastern Indian Ocean using a plankton towing net during a vertical haul from 44 sampling stations, which resulted in 168 taxa, including 60 species that were newly recorded in the study area. The main purpose of this work was to identify members of the phyla Retaria and Cercozoa and their distribution in the eastern Indian Ocean. The species’ morphology, identification, notes, and new geographical records are briefly described.

Radiolarian flux rates, their intermittency, and changes in their species compositions are assessed using data from 73 time-series sediment trap deployments (1357 samples) covering 7-12 calendar months. Results are analyzed as a function of trap depth, latitude, and seasonal and geographic variations in sea surface temperature and primary production. Radiolarian flux rates are highest in the tropics and subtropics, decreasing towards the high latitudes. Low and highly intermittent primary production (PP) regimes are reflected in more pulsating radiolarian flux rates, but in moderate to high PP areas, radiolarian fluxes are not associated with phytoplanktonic growth cycles. At sites where simultaneous trap deployments at different depths were performed, shallower traps yield lower and more pulsating radiolarian flux values than deeper ones. Enhanced dissolution of biogenic silica in the shallower traps is probably responsible for these differences. Intermittency in radiolarian flux is highest in the seasonally ice-covered Southern Ocean waters, but much lower in the also seasonally ice-covered northern hemisphere sites investigated, suggesting differences in the mechanisms that govern the production and recycling of organic matter in the upper ocean and at mid depths. Radiolarian flux rates and their species richness do not seem to be coupled, neither temporally nor geographically. Temporal stability in the composition of the radiolarian taxocoenoses is generally high, and positively associated with absolute flux values and trap depth. The bulk of the assemblages are little affected by environmental seasonality, and only a few species, albeit often numerically dominant, seem to reflect these changes. Fil: Boltovskoy, Demetrio.
