| Summary: | Megaciella lobata n. sp. (Figs. 3 & 4, Table 2) Material examined. Holotype: ZSM 20150382, collected by Jay Orr with a research survey bottom trawl (haul #166) from the FV Ocean Explorer; 17 July 2012, 91 m depth, 2.1 km north of western Kiska Island, western Aleutian Islands, Bering Sea (51°59.5740' N, 177°23.0100' E). Water temperature = 4.3°C. Complete specimen in ethanol. Description. Habitus: This is a small, brown-colored sponge of firm, only slightly elastic consistency. It has an almost circular outline where several lobes radiate from a center (Fig. 3 A). The lobes are 0.5–2 cm in thickness and up to 2 cm long, starting from a common center, 3.5 x 4.4 x 5.3 cm. Lobes may be partially fused. The surface is hispid, due to projecting spicules of choanosomal spicule tracts (Fig. 3 B). Skeletal structure: The ectosome is a thin membrane and contains scattered anisotylotes with microspined bases and microscleres (Fig. 3 C). In the choanosome, plumose tracts, cored by smooth styles (Fig. 3 D) and ... : Published as part of Lehnert, Helmut & Stone, Robert P., 2015, New species of sponges (Porifera, Demospongiae) from the Aleutian Islands and Gulf of Alaska, pp. 451-483 in Zootaxa 4033 (4) on pages 456-457, DOI: 10.11646/zootaxa.4033.4.1, http://zenodo.org/record/253595 ... |
