| Summary: | Genus Antarctotetilla Carella et al., 2016 Definition: Tetillidae with pores grouped in small surface depressions or in sieve-like areas, without porocalices and without a proper cortex, but with a loose arrangement of auxiliary oxeas at the sponge periphery (i.e. pseudocortex) (Carella et al. 2016). Diagnosis: Globular or egg shaped sponges. Surface mainly smooth and without porocalices, with one or several oscules situated on top. Pores always grouped in small surface depressions or in sieve-likes overlying a subectosomal cavity. Basal bundles of spicules at the sponge base, acting as a root system. Consistency generally compact out of the water. No a real cortex, but a pseudocortex composed of few auxiliary oxeas, perpendicular to the surface mostly concentrated at the final part of the radial spicule bundles. Choanosomal skeleton consists of spiral bundles of oxeas accompanied by anatriaenes and protriaenes radiating from the sponge center towards the surface. The bundles may pierce the ectosome in some ... : Published as part of Carella, Mirco & Uriz, Maria J., 2018, Description of two new genera (Antarctotetilla, Levantiniella) and a new species of Tetillidae, pp. 295-321 in Zootaxa 4455 (2) on pages 302-303, DOI: 10.11646/zootaxa.4455.2.3, http://zenodo.org/record/1457221 ... |
