| Summary: | Megaciella triangulata n. sp. (Figs. 5 & 6, Table 2) Material examined. Holotype ZSM 20150383 and paratype ZSM 20150384 collected by Jim Stark with a research survey bottom trawl (haul #180) from the FV Ocean Explorer; 24 July 2012, 141 m depth, Buldir Reef, western Aleutian Islands, North Pacific Ocean (52°03.4140' N, 176°25.0800' E). Water temperature = 4.1°C. Complete specimens in ethanol. Description. Habitus: Both specimens are golden brown in color on wiry stalks. The holotype (larger specimen) is 17 cm in height and 11 cm in maximum width (Fig. 5 A). The stalk of the holotype is 1.5–2 cm thick and expands after 5.5 cm into a massive triangle with sides almost symmetrical (11.5, 11 and 12 cm long) and 2.5– 3 cm in thickness. The paratype (smaller specimen) attains 14 cm in height, the stalk is 0.8 cm at the base and more irregularly shaped, it widens to 1.9 cm in diameter where it expands into a small massive triangle, the sides 4, 4.5 and 5 cm long with a thickness of 1.5 cm (Fig. 5 A). The stalk ... : 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 458-462, DOI: 10.11646/zootaxa.4033.4.1, http://zenodo.org/record/253595 ... |
