Material examined: 1 ñ, NMNS 8772-12, 5.7 × 3.7, Shanfu, Liuqiu Township, Pingtung County, 24 October 2008; 1 ò 3 ñ, NMNS 8772-13, 8.4–11.0 × 5.3–6.6, Wanlitong, Pingtung County, 13 May 2009; 1 ñ, NMNS 8772-14, 7.2 × 4.4, Wanlitong, Pingtung County, 13 November 2009; 2 ñ, NMNS 8772-15–16, 3.5–5.2 × 2.4–3.2, Shadao, Hengchun Township, Pingtung County, coll. H.- T. Hung, 16–17 October, 2020. Distribution: Indo-West Pacific; Red Sea; Hawaii Islands; French Polynesia (Serène 1984; Poupin 1996). Remark: The morphology of the present specimens (Fig. 3A, B, D, E) matches the description of Chlorodiella cytherea (Dana, 1852) (Dana 1852b: 213– 214). Ng et al. (2017: 87) cited Sasaki (1976) as the first report of Chl. cytherea from Taiwan. However, Serène (1984) noted Chl. laevissima, as reported by Miyake (1938), is a junior synonym of Chl. cytherea. Thus, Miyake (1938), rather than Sasaki (1976), should be considered the first report of this species from Taiwan.
