  • Two species from the genus Escharoides Milne Edwards, 1836, E. biseriatata and E. buffonellarioides n. sp. Were first found in Korean waters in this study. Their colonies were collected from two locations in the South Sea, Korea: Tongyeong Marine Ranch in 2004 and Daebyeon Port in 2009. Escharoides biseriatata shows a difference in the position of avicularia from the Chinese specimens. While avicularia are lateral to the orifice in Chinese specimens, the ones in Korean specimens seem to be located more latero-proximally. Since Escharoides biseriatata was reported as fouling bryozoans in China in 2001, this species first occurred at Daebyeon Port in Korea in this study. Escharoides buffonellarioides n. sp. is similar to E. adeonelloides in morphological features of zooids but is clearly distinguished by having the erect colonial form of small masses. With the addition of two species reported herein, four Korean Escharoides are recorded: E. biseriatata, E. buffonellarioides, E. excavata, and E. sauroglossa.

  • 제주도산 해산 태충류의 분류학적 연구를 위하여 1965년부터 1985년부터 제주도내의 13개 지역(제주항, 비양도, 과부탄, 가파도, 대포, 삼매봉, 범섬, 문섬, 숲섬, 서귀포, 위미리, 파랑도, 우도)에서 채집한 재료들을 동정 분류한 결과 52종을 얻었으며 이중 11종은 한국미기록종으로 나타났다. 그들은 다음과 같다. Tubulipora pulchra, Ellisina canui, Labioporella sinuosa, Mucropetraliella mucroaviculata, Emballotheca pacifica, Hippomenella spatulata, Microporella cribrosa, Smittina raigii, Smittoidea prolifica, Parasmittina triangularis 그리고 Escharoides excavata. 따라서 지금까지 보고된 제주도산 해산태충류는 74종이 된다.

  • DNA barcoding of Bryozoa or "moss animals" has hardly advanced and lacks reference sequences for correct species identification. To date only a small number of cytochrome c oxidase subunit I (COI) sequences from 82 bryozoan species have been deposited in the National Center for Biotechnology Information (NCBI) GenBank and Barcode of Life Data Systems (BOLD). We here report COI data from 53 individual samples of 29 bryozoan species collected from Korean seawater. To our knowledge this is the single largest gathering of COI barcode data of bryozoans to date. The average genetic divergence was estimated as 23.3% among species of the same genus, 25% among genera of the same family, and 1.7% at intraspecific level with a few rare exceptions having a large difference, indicating a possibility of presence of cryptic species. Our data show that COI is a very appropriate marker for species identification of bryozoans, but does not provide enough phylogenetic information at higher taxonomic ranks. Greater effort involving larger taxon sampling for the barcode analyses is needed for bryozoan taxonomy.

  • 한국산 입이끼벌레과에 속하는 6종을 동정하였으며 그 중 2종에 대해 재검토를 하였다. 그 결과 제주도의 과부탄으로부터 보고되었던 라이기입이끼벌레[Smittina raigii (Audouin, 1825)]는 한국미기록종인 톱니조두체이끼벌레(Parasmittina serrula Soule and Soule, 1973)로 재보고한다. 또한 망태양입이끼벌레 [Smittoidea reticulata (MacGillivray, 1847)]는 태평양에는 서식하지 않는 종이므로 한국의 태형동물상에서 삭제되고 망태양입이끼벌레로 동정되었던 한국산 표본은 태양입이끼벌레 (Smittoidea pacifica Soule and Soule, 1973)로 동종이명처리된다. 따라서 한국산 입이끼벌레류는 14종이 된다.

  • We performed a taxonomic study on Korean Pacificincolidae (Bryozoa: Cheilostomata) with the materials collected from 39 localities(ports, intertidal and subtidal zones) in the coastal seas of South Korea from 1981 to 2020. Korean Mucronella perforata reported by Rho and Seo (1985) turned out to be not Pacificincola perforata, but Primavelans glabricollaris n. sp. based on morphological data. Pacificincola perforata, which was transferred from Mucronella perforata (Okada and Mawatari, 1937), is also added to the Korean fauna. This study is the first to use mitochondrial 16S rRNA gene sequences to study the family Paficincolidae. The NJ analysis also reconfirmed the validity of the genus Primavelans, established on the basis of the early astogeny by De Blauwe in 2006, with the mitochondrial 16S rRNA sequences. The inter-genetic distance among two species belong to the Pacificincolidae was in the range of 13.39±1.83 mm. Primavelans glabricollaris n. sp. is thus distinguished from Pacificincola perforata with both morphological and molecular data. A new species, Primavelans glabricollaris, and a new record, Pacificincola perforata from Korea are herein described in detail and illustrated by scanning electron microscopy.

  • Three cheilostomatous bryozoan species collected from Gageodo Island of Korea in 1999, which are Chorizopora brongniartii (Audouin, 1826), Microporella marsupiata (Busk, 1860) and Celleporina costazii (Audouin, 1826), are newly added to the Korean fauna. The redescriptions of three species are provided with distributional data and detailed illustrations herein. As a result of this study, a total of 32 bryozoan species from Gageodo Island waters are now reported.
