FIGURE 11. Plumatella wiebachi n. sp., Specimen No. 56. (a) Colony surrounded by sessoblasts, scale bar = 3 mm; (b) colony showing greater detail, scale bar = 1 mm; (c) floatoblast valves with dorsal valve on the left, scale bar = 100 μm; (d–g) com-parison of statoblasts in Plumatella javanica and Plumatella wiebachi n. sp. (d) P. javanica floatoblast fenestra showing optical points of light around each tubercle; (e) P. javanica sessoblast from the author's personal collection from Thailand showing relatively large tubercles; (f) P. wiebachi n. sp. floatoblast fenestra showing the absence of such points of light; (g) P. wiebachi n. sp. sessoblast showing relatively small tubercles. Scale bars for figs. 11d–g = 100 μm.
