Antarctotetilla pilosa nov. sp. Material examined: 1 individual (holotype, CEAB. POR. BIO.502a ANT 27211), South Orkneys, Subantarctic region, - 61° 8.74‘S, -43° 58.15‘W, 407 m depth, 19 February 2011 (Carella et al. 2016). GenBank accession numbers (Carella et al. 2016): CEAB.POR.BIO.502a ANT 27211(KT124313 see S1, KT124355 and KT124361). Description (Fig. 12). Globular, 8 cm in diameter sponge (Fig. 12a, b and c).Long hairy hispidation protruding up to 2 cm, throughout the surface, caused by long fusiform oxeas, protriaenes, and sometimes anatriaenes. This hispidation becomes much longer (up to 4 cm) after sponge desiccation due to flesh retraction. Oscules of several sizes spread on the sponge body (Fig. 12d). Pores grouped in more or less deep surface depressions (Fig. 12e). Pseudocortex (Fig. 12f) composed of loose auxiliary oxeas perpendicular to the sponge surface. Megascleres: oxeas, protriaenes, anatriaenes, and trichodal protriaenes; microscleres: sigmaspires. A basal root-tuft system of ... : 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 311-313, DOI: 10.11646/zootaxa.4455.2.3, http://zenodo.org/record/1457221 ...
