| Summary: | Esperiopsis flagrum sp. nov. (Fig. 12 a–d, Fig. 13 a–d) Description Similar whiplike growth form (Fig. 12 a, b) as known from the genera Asbestopluma and Euchelipluma elongata sp. nov., described above. The holotype was broken in half during collection but the specimen had a total length of 54 cm. This specimen was encrusted near its base with the demosponge Lissodendoryx oxeata Koltun, 1958. The specimen is a beige, cylindrical sponge, tapering towards the top end, beset with numerous whitish thin processes, 3–5 mm in length, elastic but somewhat stiff. The diameter, without the whitish filaments, is 4 mm at the base, 2.5 mm at the tip. This axis is compressible, elastic but resilient. Skeleton: There is no special ectosome developed. The central axis of the longitudinal sponge consists of interwoven polyspicular tracts of styles with many microscleres in between. Single tracts are 150–600 µm in diameter. The lateral processes are supported by single polyspicular tracts running into them. The outermost ... : Published as part of Lehnert, Helmut, Stone, Robert & Heimler, Wolfgang, 2006, New species of deepsea demosponges (Porifera) from the Aleutian Islands (Alaska, USA), pp. 1-35 in Zootaxa 1250 on pages 20-23, DOI: 10.5281/zenodo.173010 ... |
