Description. Observed colony tubular, branching, light or yellowish brown; almost entirely recumbent, with ends of branches usually swollen; surface encrusted. Tentacle number 32 – 64. Floatoblasts in our material oval, 353 – 378 (366 ± 6) μm long by 235 – 272 (256 ± 11) μm wide (n = 10), with length / width ratio of about 1.4. Fenestra of floatoblast almost circular; surface of fenestra covered with rounded tubercles; annulus smooth (Fig. 2 E); valves almost symmetrical in lateral view. Sessoblast fenestra also covered with tubercles; annulus weakly reticulate (Wood & Okamura 2005).

Remarks. The colony and statoblasts of Plumatella repens vary environmentally, and the floatoblast is the commonest gross morphological type among plumatellids. Accordingly, other species with similar gross floatoblast morphology (e. g. P. fungosa and P. rugosa may have been misidentified as P. repens before SEM was used for observations.

Distribution. Plumatella repens is common, and broadly distributed worldwide; distributed from Okinawa to Hokkaido in Japan.
