Entactinaria Kozur & Mostler 1982

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.
