The Red Algal Genus Scinaia (Galaxauraceae, Nemaliales) on Jeju Island,Korea

Bivona-Bernardi (1822) established the genus Scinaia on the basis of the monotypic species S. forcellata. For many years, this species was cited as S. furcellata (Turner) Bivona-Bernardi. However, recently, the specific epithet, S. forcellata Bivona-Bernardi, was restored (Dixon and Irvine 1970; Huisman 1985). The genera Scinaia BivonaBernardi (1822), Gloiophloea J. Agardh(1872), Pseudoscinaia Setchell (1914), and Pseudogloiophloea Levering(1955) at one time comprised the Scinaia assemblage, but Pseudoscinaia and Pseudogloiophloea, have now been merged into Scinaia (Huisman 1985). In Korea, three Scinaia species have been recorded (Lee and Kang 2002): S. japonica Setchell (1914), S. latifrons Howe (1911), and S. okamurae (Setchell) Huisman (1985). Apart from the record of its occurrence, no information, such as locality or morphology, has been published for Scinaia latifrons (Lee and Kang 1986). Scinaia japonica is well-known from Korean waters (Okamura 1936; Yamamoto and Kawamoto 1942; Rho 1954, 1958; Chyung and Park 1955; Kang 1956, 1960, 1966, 1968; Lee 1976; Lee and Kang 1986; Koh 1990; Lee and Koh 1991; Park et al. 1994; Lee and Kim 1999; Lee et al. 2000). Scinaia okamurae was previously referred to as Gloiophloea okamurae Setchell or Pseudogloiophloea okamurae (Setchell) Chihara (Kang 1968; Lee and Kang 1986; Lee and Koh 1991).
