Monoplectroninia Pouliquen & Vacelet 1970
No full textGenus Monoplectroninia Pouliquen & Vacelet, 1970 TYPE SPECIES. — Monoplectroninia hispida Pouliquen & Vacelet, 1970 by monotypy. DIAGNOSIS. — Minchinellidae in which the choanoskeleton is composed of a basal layer made of one category of small tetractines cemented together by their basal actines, while their apical actine remains free and points outward. The cortical skeleton consists of free spicules.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 258, DOI: 10.5281/zenodo.539217
Lithonida Vacelet 1981
No full textOrder LITHONIDA Vacelet, 1981 <p>DIAGNOSIS. — Calcaronea with reinforced skeleton consisting either of linked or cemented basal actines of tetractines, or of a rigid basal mass of calcite. Diapason spicules are generally present and the canal system is leuconoid.</p> <p>DESCRIPTION</p> <p>The families Lelapiellidae (Calcinea), Lepidoleuconidae (Baeriida) and Lelapiidae (Leucosoleniida) are now excluded from this order.</p>Published as part of <i>Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2)</i> on page 256, DOI: <a href="http://zenodo.org/record/5392175">10.5281/zenodo.5392175</a>
Tulearinia Vacelet 1977
No full textGenus <i>Tulearinia</i> Vacelet, 1977 <p> TYPE SPECIES. — <i>Tulearinia stylifera</i> Vacelet, 1977 by monotypy.</p> <p>DIAGNOSIS. — Minchinellidae (?) with a basal skeleton consisting of tetractines with basal actines that are interwoven but are not cemented, and with underlying layers of triactines linked in the same way.</p> <p>DESCRIPTION</p> <p>This genus may represent the first step in the process of the spicule linkage that is characteristic of Minchinellidae (Fig. 52). However, its inclusion in this family is questionable because the actine tips are only slightly modified, and true zygosis and diapasons are absent.</p>Published as part of <i>Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2)</i> on page 258, DOI: <a href="http://zenodo.org/record/5392175">10.5281/zenodo.5392175</a>
Baeriidae Borojevic & Boury-Esnault & Vacelet 2000, n. fam.
No full textFamily BAERIIDAE n. fam. TYPE GENUS. — Baeria Miklucho-Maclay, 1870 by original designation. DIAGNOSIS. — Baeriida with a choanoskeleton consisting of giant triactines, and/or of tetractines in no particular order, and/or of very numerous microdiactines. No traces of radial organization can be seen in the choanoskeleton. The cortical skeleton consists of triactines, giant diactines, and/or numerous microdiactines, and occasionally the basal actines of cortical giant tetractines. The choanoskeleton consists of scattered spicules similar to those observed in the cortex, to which numerous microdiactines can be added, or which can be entirely replaced by microdiactines. The exhalant aquiferous system is formed by ramified canals that have no tangential skeleton, being loosely or densely covered by harpoon-shaped pugioles and/or microdiactines.Published as part of Borojevic, Radovan, Boury-Esnault, Nicole & Vacelet, Jean, 2000, A revision of the supraspecific classification of the subclass Calcaronea (Porifera, class Calcarea), pp. 203-263 in Zoosystema 22 (2) on page 251, DOI: 10.5281/zenodo.539217

Cladorhizidae with palmate anisochelae (from Hajdu & Vacelet, 2002).Published as part of Kelly, Michelle & Vacelet, Jean, 2011, Three new remarkable carnivorous sponges (Porifera, Cladorhizidae) from deep New Zealand and Australian (Macquarie Island) waters, pp. 55-68 in Zootaxa 2976 on page 60, DOI: 10.5281/zenodo.27826

Cercicladia Rios, Kelly & Vacelet, 2011, gen. nov.
No full textGenus Cercicladia gen. nov. Type species. Cercicladia australis gen. nov. sp. nov., here designated. Diagnosis. Cladorhizidae with cercichelae, microxeas, and rare toxas, in addition to the usual mycalostyles and sigmancistras. Acanthosubtylostyles may be present. Body feather–shaped (pinnate), with a long, thick fleshy pedicle, and a long flattened blade at the apex. Long fine filaments extend on either side of the blade forming an incurved feather–like structure. Etymology. Named for the shape of the special microsclere, the cercichela, which resembles a shuttle (cerc, Greek), a tool designed to compactly store weft yarn as it is guided between the vertical warp yarns on the loom in the craft of hand weaving. The suffix – cladia, or branch, is frequently used in the Cladorhizidae (clad, ancient Greek).Published as part of Rios, Pilar, Kelly, Michelle & Vacelet, Jean, 2011, Cercicladia australis, a new carnivorous sponge with novel chelae from the Tasman Basin and the Argentine Patagonian Margin (Porifera, Cladorhizidae), pp. 52-62 in Zootaxa 3131 on page 54, DOI: 10.5281/zenodo.20564
