  • During the course of taxonomic study on the genus Chromis from the southern coastal waters off Cheju Island during April-August 1993, eight specimens have been classified as Chromis analis(Cuvier) for the first time in Korea, and thus described here as new to the Korean fish fauna. Damselfish, Chromis analis was originally described by Cuvier and Valenciennes(1830) from Ambonia, Indonesia. Chromis notatus is the only species to date in the genus Chromis distributed around Korean waters, according to Chyung(1977). Chromis analis is distinguished from Chromis notatus by three spiniform procurrent caudal rays, a deeper body and a golden or brown yellowish body and fin color. Norang-ja-ri-dom is proposed as the Korean name for Chromis analis.

  • Comparative osteology of Chromis notata, C. analis and C. fumea was studied based on the samples collected from the Korean waters. The three species are distinguished by the shape of cranium, visceral skeleton, vertebra and caudal skeleton. Chromis notata has a glossohyal which is slightly curved in shape while two other species are deeply curved. C. analis has three spiniform procurrent caudal rays while others have two. C. fumes could be distinguished easily by the shape of preopercle which is serrate in posterior margin. This investigator reveals following bones as new taxonomic criteria for the genus Chromis in Korea. In cranium, height of supraoccipital, height of process of parasphenoid and anterior margin of basisphenoid, in visceral skeleton, presence of fine papilla-like process at the surface of preopercular sensory canal, in orbital bone, width of preorbital, in hyoid arch, shape of glossohyal, union state between lower hypohyal and ceratohyal and union state between ceratohyal and epihyal, in shoulder girdle bone, dorsal margin of posttemporal, width of upper postclavicle, posterior end of lower postclavicle and posterior margin of first actinost bone, in vertebrae, beginning point of parapophysis, in caudal skeleton, upper shape of second neural spine of pleural centrum.

  • The Damselfish, Chromis fumea, was originally described by Tanaka(1917) from Nagasaki, Japan. In the Korean waters, 27 specimens of Chromis fumea(Tanaka) were collected from Cheju-do, on April-August, 1993, and described herewith as new to the Korean fish fauna. Chromis fumea differs from Chromis notatus in having serrate preopercle, no distinctive black spot in pectoral base and caudal fin with a broad blackish band in each lobe. Yeonrnoo-ja-ri-dom is proposed as Korean name of Chromis fumea.

  • External morphology of three species of damselfishes, Chromis notata, C. analis and C. fumea were studied based on the samples collected from the Korean waters from 1993 to 1994. In morphology of the black spot at base of pectoral fins, C. notata has a large triangluar spot at Cheju population and a small circular spot at Sin - am. In the length of pelvic fin, C. notata of Korea can be classified into 3 groups. First group has a pelvic fin that extends to the origin of anal fin, second extends to the anus, third not extend to the anus. C. analis has higher body depth than C. notata and C. fumea in % of standard length. C. fumea has a minute serrate preopercle and no black spot at base of pectoral fins. In distribution, C. notata has a more widly distriubtion area than C. analis and C. fumea. Therefore, C. notata has more tolerance of cold waters than C. analis and C. fumea.

  • The subfamily Chrominae of damselfishes (Teleostei: Pomacentridae) includes the genus Chromis and Dascyllus. They are found throughout the tropical oceans and form a major component of coral reef communities. There are 5 species of the Chrominae currently recognized in Korea. This study was conducted to infer phylogenetic position of two Korean Chromis species and one Dascyllus species within general category of their each genus in worldwide level. This study also includes one species of Japanese Dascyllus. In the phylogenetic analysis, the Japanese D. aruanus grouped with D. aruanus previously reported from French Polynesia. Korean Chromis fumea grouped with Australian C. nitida and the p-distance value between the two species is relatively very low (0.047). Korean C. notatus grouped together with C. flavomaculata (New Caledonia). In the sequence analysis of some Korean and Japanese damselfishes, there was no sequence variation between D. melanurus (Jeju, Korea) and D. melanurus (Indo-Pacific), but the sequences of the two populations were different in only one nucleotide sites from that of D. melanurus in Indonesian Archipelago. The sequences of Dascyllus aruanus (Japan) were different in two nucleotide sites from it in French Polynesia. There were high difference between the sequences of two Korean species, Chromis fumea and Korean C. notatus. The variations among mitochondrial cytochrome b sequences indicate that the gene sequence could be used as DNA barcode for identification of local populations of D. aruaus and D. melanurus as well as species level.
