    Amphicocconeis cf. mascarenica Riaux-Gobin & Compère, 2011 (Figs 62–67). Table 1 Remarks:—The measurements and features of the specimens from the Pacific islands (Raivavae, Tahiti and Moorea Isls, Table 1) are close to those from the Mascarenes (Riaux-Gobin et al. 2011: tabl. 2), i.e., with valvocopulae with regularly biseriate rows of simple pores. This taxon is dominant on the Society Archipelago (Tahiti and Moorea Isls) as well as in the Austral Archipelago (Raivavae Isl.). In Tuamotu and Marquesas Archipelagos, Amphicocconeis are less abundant, but with, here again, A. cf. mascarenica as dominant taxon (pers. obs.).Published as part of Riaux-Gobin, Catherine, Garcia, Marinês, Witkowski, Andrzej, Saenz-Agudelo, Pablo, Coste, Michel & Daniszewska-Kowalczyk, Genowefa, 2021, New Amphicocconeis (Bacillariophyta) from Raivavae and Tahiti Islands (South Pacific) and Porto Belo (Brazil), with re-examination of Psammococconeis, pp. 30-54 in Phytotaxa 513 (1) on page 52, DOI: 10.11646/phytotaxa.513.1.2, http://zenodo.org/record/530693

    Pratiques religieuses (afro-)cubaines

    No full text
    Du triomphe de la Révolution castriste (1959) jusqu’au début de la « Période spéciale en temps de paix » (état de crise nationale consécutif à l’effondrement de l’URSS), les recherches empiriques sur Cuba ont surtout été conduites par des chercheurs de l’île. Les réorientations idéologiques et socio-économiques de la Période spéciale ont toutefois changé la donne en permettant à des recherches étrangères de terrain de se développer, en particulier sur la question des religions dites « afro-cubaines ». Manifestations socioreligieuses protéiformes, celles-ci se sont en effet érigées en un objet d’étude privilégié tant parce qu’elles jouent un rôle primordial dans l’organisation, au quotidien, de l’expérience et des représentations du monde de leurs nombreux adeptes, que parce qu’elles jouissent d’une visibilité singulière dans la Cuba contemporaine. Rassemblant des articles fondés sur des ethnographies récentes et approfondies, ce numéro témoigne de la diversité et du dynamisme de cet univers religieux ainsi que des recherches qu’il suscite actuellement. Il vise notamment à contribuer à une meilleure appréhension anthropologique des logiques rituelles et sociales qui sous-tendent les pratiques envisagées et, ce faisant, insiste sur les processus complexes de construction et de négociation des identités personnelles et collectives qui s’y développent, en marge ou au cœur des enjeux les plus forts qui traversent la société cubaine d’aujourd’hui. Contributeurs : Ana Stela de Almeida Cunha, Diana Espirito Santo, Emma Gobin, Katerina Kerestetzi, Alain Konen, Géraldine Morel Between the Revolution of 1959 and the beginning of the ‘Special Period in Peacetime’—the period of national crisis that followed the demise of the USSR—empirical studies in and on Cuba were predominantly conducted by Cuban researchers. The ideological and socioeconomic reorientations adopted during the Special Period significantly changed this situation, allowing foreign researchers to undertake fieldwork on the island, particularly on the subject of so-called “Afro-Cuban” religions. Indeed, these protean socio-religious phenomena have recently emerged as a major research topic, as they play a key-role in the organisation of the everyday life and worldviews of their many followers and have singular visibility in contemporary Cuba. Based on recent, detailed ethnographies, this collection of articles illustrates the diversity of this religious world and the dynamism of the studies it is currently inspiring. In particular, the collection aims to contribute to a better anthropological understanding of the ritual and social logic underpinning (Afro‑)Cuban religious practices. In doing so, it highlights how they generate complex processes of personal and collective identity construction and negotiation, which develop both in the fringe and at the heart of the major issues Cuban society faces today.

    Amphicocconeis catharinensis Riaux-Gobin & Garcia. SEM, Figs 7–17. Table 1 Description:— SEM.Valves robust, oval-elliptic, with round apices. Valve length 18 ± 3 µm, 14–22 µm. Valve width 11 ± 2 µm, 9–13 µm; n = 10 (SEM) (Table 1). SV: surface convex, striae radiate and regularly spaced, uniseriate, composed of large rectangular areolae. On the valve face, each areola is positioned on the bottom of a depression with opening bordered by digit flaps (Figs 8–9). Areolae are internally closed by hymenes (Figs 10–12). On the mantle, each oblong areola is separated from the next by a granular and concave plain structure of triangular to rectangular shape (Figs 8–9, arrows). Short marginal striae not observed. 11 ± 1 SV stria in 10 µm. SVVC relatively narrow with big pores corresponding to each areola. RV: surface flat, striae radiate, composed of macro-areolae (large along the margin, short along the raphe, with short areolae dispersed in between, Fig. 13). Terminal-distal raphe endings strongly curved on same side (Figs 13, 15). Proximal raphe endings slightly enlarged and curved on same side (opposite to the terminal raphe endings, Fig. 16). 26 ± 2.5 RV stria in 10 µm. RVVC 1/4 of the valve width, with marginal transapical oblong pores corresponding to each macro-alreola (Fig. 17, twin arrowheads). Remarks:—The SV of Amphicocconeis catharinensis was illustrated as being the SV of Psammococconeis disculoides in Garcia (2001: figs 21, 23). The specific ornamentation of the SV mantle, with a concave structure in between each oblong areola (Figs 8–9) seems unique. The RV of A. catharinensis has some similarities with that of A. disculoides and A. debesi (large area with short radiate macro-areolae), but these short areolae in median-area are in very low density in A. catharinensis (Fig. 13), furthermore the SV of A. catharinensis is highly dissimilar to that of Amphicocconeis disculoides (Hustedt) De Stefano & Marino (figs 2–3, 6– 7 in De Stefano & Marino 2003; Figs 1). Type locality:—Zimbros, Peninsula do Porto Belo, Santa Catarina State, Brazil. Holotype:—Stub 4 19/06/2020, BM001222889. Holotype specimen illustrated in Fig. 7. Etymology:—The epithet refers to the location of the type habitat of this taxon in Brazil (locality Santa Catarina State).Published as part of Riaux-Gobin, Catherine, Garcia, Marinês, Witkowski, Andrzej, Saenz-Agudelo, Pablo, Coste, Michel & Daniszewska-Kowalczyk, Genowefa, 2021, New Amphicocconeis (Bacillariophyta) from Raivavae and Tahiti Islands (South Pacific) and Porto Belo (Brazil), with re-examination of Psammococconeis, pp. 30-54 in Phytotaxa 513 (1) on page 44, DOI: 10.11646/phytotaxa.513.1.2, http://zenodo.org/record/530693

    <i>Amphicocconeis ruatara</i> Riaux-Gobin sp. nov. SEM Figs 49–61. Table 1 <p> <b>Description</b>:— <b>SEM.</b> Valves oblong-elliptic to elongate, with slightly rostrate apices (Fig. 51). Axially bent in cingular view. Valve length 15 ± 2 µm, 14–17 µm. Valve width 6 ± 2 µm, 6–8 µm; L/ W 6.2 ± 0.8; n = 54 (SEM) (Table 1). SV convex with a concave narrow sternum (Figs 49–50). One row of large and transapically elongated areolae on each part of the sternum, one marginal row of dense and short areolae and, in between these two sectors, short areolae arranged more or less in quincunx. Often a low crest (or <i>crista marginalis</i>) delineating the marginal row of dense and short areolae, as a sort of short mantle (Figs 49–50, arrow). SV striae parallel in mid-valve, slightly radiate and denser on apices, uniseriate. SV striae 22 ± 3 in 10 µm. SVVC open, narrow (or sometimes larger), composed of short fused fimbriae (27 in 10 µm), separated from each other by an irregularly biseriate row of pores (Figs 52–54), festooned edge. Head pole of the SVVC with very short fimbriae. RV flat, dense striae composed of one narrow macro-areola, short supplementary marginal striae on mid-valve (Fig. 55). Raphe filiform. Proximal raphe endings externally simple and relatively close to each other, central nodule slightly elevated externally and unique for the genus (Figs 55–56, 59). Terminal raphe endings largely hooked on the mantle (Fig. 58). Raphe sternum somewhat elevated internally, with raphe slit slightly undulating. Proximal raphe endings simple and coaxial internally (Fig. 57). Central area small. RV striae 51 ± 6.5 in 10 µm; 42–60 in 10 µm.
