Yun-Chih Liao, Li-Shu Chen, Kwang-Tsao Shao, and I-Shuing Chen (2004) In
total, 30 species belonging to 7 genera and 2 subfamilies of the family
Scaridae are found in Taiwan. Among them, 4 species, Calotomus
japonicus, Scarus chameleon, S. quoyi, and S. spinus, are recorded for
the 1st time from Taiwan. The biogeographical distribution of Calotomus
japonicus is extended southwards to southern Taiwan. According to
Bellwood (1994), 5 species previously classified into the genus Scarus
in Shen et al. (1993) should be placed in the genus Chlorurus: C.
bowersi, C. japanensis, C. microrhinos, C. oedema, and C. sordidus. The
2nd and 3rd species mentioned above were respectively used as junior
synonyms of S. pyrrhurus and S. gibbus. Furthermore, we found specimens
which would be a new species of Scarus since its morphological and
molecular data show significant differences from other congeneric
species. Because most of the parrotfish specimens in Shao and Chen
(1989) were damaged or discarded, we recollected and re-deposited
almost all of them to the Research Museum of the Institute of Zoology,
Academia Sinica, Taipei. In addition to detailed descriptions of the 4
newly recorded species and 1 doubtful species, the synonym lists,
catalog numbers of deposited specimens, and distributions of the
remaining 26 species were also compiled. A diagnostic key to the
species, and color plates of all parrotfish species of Taiwan are also
provided in this paper.
Key words: Fish fauna, Parrotfishes, Taxonomy, New records, Zoogeography.
