| Summary: | Leucascus lobatus Rapp, 2004 Diagnosis: Cortex composed of tripods with a fourth rudimentary actine. Skeleton of the tubes composed of triactines and tetractines with cylindrical actines. Synonymies: Leucosolenia primordialis: Brøndsted 1933: 4 (see Rapp 2004), Leucascus lobatus: Rapp 2004: 119. Type material: ZMUC POR-245 (Holotype; Kap Farvel (6007.7’N, 4417’W), Greenland; Kap Farvel Expedition; 08/08/1970; depth: 230 to 250 m; substratum composed of large stones). Type locality: Kap Farvel, Greenland. Description: Colour is white after fixation. The cormus is lobate and the oscula are surrounded by membrane. The surface is smooth and perforated by inhalant apertures (Figure 6 A). The tubes are tightly and regularly anastomosed. The atrial surface is smooth. Reproductive elements are present. Skeleton: The cortical membrane could be recognized only in some regions (Figure 6 B). The cortical skeleton is formed by tripods varying in size and organized in several layers. These spicules are exclusively ... : Published as part of Cavalcanti, Fernanda F., Rapp, Hans Tore & Klautau, Michelle, 2013, Taxonomic revision of Leucascus Dendy, 1892 (Porifera: Calcarea) with revalidation of Ascoleucetta Dendy & Frederick, 1924 and description of three new species, pp. 275-314 in Zootaxa 3619 (3) on pages 285-287, DOI: 10.11646/zootaxa.3619.3.3, http://zenodo.org/record/221852 ... |
