Celleporella nodasakae Dick, Grischenko & Mawatari, 2005 (Figs 15–18) Celleporella nodasakae Dick, Grischenko & Mawatari, 2005: 3729, fig. 11. Material examined. NIBRIV0000325935, Dumujin, Baengnyeong Island. Other material: Woosuk University collection—Baengnyeong Island: Hwadong (8 colonies), Junghwadong (1 colony), Dumujin (96 colonies), Jinchon-ri (4 colonies); also Ui Island (1 colony). All colonies on rocky substrata. Description. Colony encrusting, mostly unilaminar, up to 15 mm in maximum spread. Zooids more or less regularly to irregularly disposed on the substratum, occasionally overgrowing neighboring zooids; slightly disjunct, with 2–5 small interzooidal spaces along each side of the zooid, depending on whether it is an autozooid or a sexual polymorph. Gymnocystal frontal shield with a series of weak transverse striae or ridges. Autozooids more or less elongate-oval to subclavate, highest suborally, widest just distal to midlength. Orificial sinus deep, U- to roundly Vshaped, with small triangular to peg-like condyles on the ‘shoulders’ of the orifice. Female zooids more or less conical, whether longer than wide or wider than long, smaller than the ooecium; female orifice wider than long, with a distinctive frontal profile deriving from the short, rounded sinus and the shoulders that slope obliquely to the proximal corners. Ooecium prominent, more or less smooth, with mostly 4 pseudopores in a distal arc, sometimes 1–2 additional smaller pores mid-distally. Skeletally distinct male zooids not seen. Tubular lateral pore-chambers present. Ancestrula and early astogeny not seen. Measurements. ZL, 324–374 (348) µm; ZW, 144–177 (160) µm; OrL, 68–86 (75) µm; OrW, 62–69 (64) µm; OoL, 136–146 (141) µm; OoW, 161–165 (163) µm. Remarks. The material from South Korea accords well with the description of the species given by Dick et al . (2005), in particular the disjunct nature of the zooids, the distinctive female orifice, and the absence of skeletally distinct male zooids. The autozooidal orifice in the type material appears to be a little wider, with slightly stouter condyles, however. Distribution. Celleporella nodasakae was previously known only from Ketchikan, Alaska, where it also occurs intertidally.
