| Summary: | Latrunculia occulta sp. nov. (Fig. 17 a–b) Description Thinly encrusting on Chondrocladia concrescens. Not detectable by the unaided eye. Surface smooth, same whitish colour as Chondrocladia (in ethanol). No styles detected. This species was observed as a very thin encrustation with a thickness of only a unispicular layer of anisodiscorhabds on the Chondrocladia. All discorhabds are, as in the previous species, arranged parallel to each other and perpendicular to the surface. The discorhabds measure 42–54 µm and are almost smooth and rounded. The discs of the discorhabds do not consist, as in all other species, of a row of large spines but are two solid discs, their margins only slightly acanthose (Fig. 17 a, b). The ends of the spicule are two differently sized spheres which are again slightly acanthose. The rather complicated terminology of the anisodiscorhabds (i.e. a succession of manubrium, median whorl, subsidiary whorl, apical whorl and apex) does not really apply to this species. One whorl is ... : 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 30-32, DOI: 10.5281/zenodo.173010 ... |
