  • Two scleractinian species are newly recorded in Korea: Leptoseris mycetoseroides Wells, 1954 and Phyllangia hayamaensis (Eguchi, 1968). The two genera Leptoseris Milne Edwards and Haime, 1849 and Phyllangia Milne Edwards and Haime, 1848 are also newly recorded in Korea. The specimens were collected from the subtidal zones of Jeju-do Island, Korea by SCUBA diving from 1991 to 2007. Leptoseris mycetoseroides is characterized by its platelike growth form, intratentacular budding, irregularly developed collines, single styliform columella, and even septa and septocostae. Phyllangia hayamaensis is distinguished by its encrusting and plocoid growth form of corallites basally united with common coenosteum, trabecular columella, and irregular septal arrangements and paliform lobes.

  • Dendrophyllia compressa Ogawa and Takahashi, 1995 is newly reported from Korea. The specimen was collected off Seogwipo, Jeju-do, Korea in 1969. It is described herein based on the morphological characters of the skeletal structures. Dendrophyllia compressa is characterized by its small and bushy growth form with branches, vertical growth direction, small calicular diameter, compressed calice, Pourtalès Plan with vertical septal inner edges, flat and spongy columella, exserted septal upper margins, and epitheca. Dendrophyllia compressa has been synonymized with Cladopsammia eguchii . However, the former species differs from the latter species in its growth form, growth direction, colony size, corallite size, and corallite shape.

  • The two zooxanthellate scleractinian corals are newly recorded in Korea: Psammocora albopicta Benzoni, 2006 of the family Psammocoridae and Oulastrea crispata (Lamarck, 1816) of the family Faviidae. These families are also newly recorded in Korea. Specimens were collected from the subtidal zones of Jeju-do Island, Korea by SCUBA diving from 1999 to 2014. Two scleractinians are described based on the morphological characters of skeletal structures. Psammocora albopicta is distinguished by its encrusting cerioid growth form, high density of corallites, small calicular diameter, single styliform columella, and fewer rows of enclosed septa. Oulastrea crispata is characterized by its encrusting plocoid growth form, polygonal calicular shape, irregular paliform lobes, and papillose columella.

  • The Korean scleractinians examined in the present study are seven species in five families . They have six kinds of cnidae ; atrichous isorhizas, basitrichous isorhizas, holotrichous isorhizas, microbasis p-mastigophores, microbasic b-mastigophores and spirocysts, of which the holotrichous isorhizas, microbasic p-mastigophores and spirocysts are distributed in all species. The atrichous and basitrichous isorhizas are present very rare in Korean scleractinians. Especially the microbasic p-mastigophores are common in most parts of all species.

  • The four species of the family Dendrophylliidae are newly recorded in Korea: Balanophyllia (Balanophyllia) cumingii Milne Edwards and Haime, 1848, Balanophyllia (Balanophyllia) vanderhorsti Cairns, 2001, Cladopsammia eguchii (Wells, 1982), and Cladopsammia gracilis (Milne Edwards and Haime, 1848). The two genera of Balanophyllia and Cladopsammia, to which the four species belong, are newly recorded in Korea. They were collected from the subtidal zones in Jeju-do Island, Korea by SCUBA diving from 1987 to 2012. This study aims to identify the four dendrophyllid species based on external and internal morphological characters including growth form, size, budding, and color of colonies, shape and size of corallites, columella, theca, and septa. Balanophyllia (Balanophyllia) cumingii is distinguished by its solitary growth form, small and low subturbinate corallite with enlarged calice, and expanded basal part, exsert first and second septa, and Pourtal$\acute{e}$s plan. Balanophyllia (Balanophyllia) vanderhorsti is characterized by its quasi-colonial growth form, subturbinate corallites with compressed calice, thick theca, and Pourtal$\acute{e}$s plan. Cladopsammia eguchii is characterized by its phaceloid growth form of compressed corallites basally united with common coenosteum, flat spongy columella, thick theca, and Pourtal$\acute{e}$s plan. Cladopsammia gracilis is distinguished by its phaceloid growth form of corallites basally united with common coenosteum, and pronounced Pourtal$\acute{e}$s plan forming flower patterns.

  • The stony corals known from Korean waters are 24 species , 15 genera, 7 families in 5 suborders, of which 7 species are newly recorded to the Korean scleractinian fauna ; Montipora trabeculata, Oulangia stokesiana miltoni, Goniocorella dumosa, Dendrophyllia arbuscula, D.boschmai cyathohelioides, D. micranthus, and Rhizopsammia minuta mutsuensis. They were collected from 35 localities of southern Korea from 1969 to 1986. For the geographical analysis, the coastal waters of Koarea are divided into four regions ; the Yellow Sea, the Korea Strait, the Cheju Island area and the East Sea (Sea of Japan) . These are based on the species diversity , the geographical distribution form, and the community coefficient, Korean scleractinians consists of 8 temperate zone forms(33.3%, Te) and 16 tropical forms(66.7%, Tr) . Concerning the distribution in each region, 3 spp. (2 Te, 1 Tr) occur in the Yellow Sea, 9 Spp. (5 Te, 4 Tr) in the Korea Strait, 16 spp.(4 Te, 12 Tr) in the Cheju Island area and 5 spp. (2 Te, 3 Tr) in the East Sea. The communicty coefficient between the Korea strait and the East Sea is the highest (0.596), and that between the Yellow Sea and the Cheju Island area is the lowest(0).

  • Systematic relationship of 13 species representing seven orders of anthozoans, and one hydrozoan as an outgroup, were investigated. Distance and parsimony methods were used to analyze nucleotide sequence data obtained from the 18S rDNA. The inferred phylogeny indicates that two orders, Ceriantharia and Antipatharia within subclass Ceriantipatharia, are not closely related to each other. Instead, the former appears to be the most ancestral group among anthozoans but the latter is more closely related to order Actiniaria within subclass Zoantharia. The result also indicates that the actiniarian may not be a monophyletic group, because Epiactis Japonica is related more to order Scleractinia. Subclass Octocorallia appears to be a monophyletic group, within which order Pennatulacea diversed at first, and then orders Alcyonacea and Gorgonacea diversed later.
