남해 중앙부의 가막만 입구해역에 설치된 sediment trap의 와편모조 시스트 및 시스트에서 발아된 유영세포에서 국내 미기록 와편모조 시스트 9종을 관찰하였기에 형태적 특징을 고찰하였다. 미기록 와편모조 시스트는 모두 종속영양종으로 와편모조문 (Dinophyta), 와편모조강 (Dinophyceae), 페리디니움목 (Peridiniales)에 속하였다. 미기록 종은 Brigantedinium majusculum (Protoperidinium sinuosum), cyst of Diplopsalis lebourae, cyst of Protoperidinium excentricum, cyst of Pt. sp. cf. nudum, cyst of Pt. obtusum, cyst of Pt. ventricum, cyst of Protoperidinium sp.1, cyst of Protoperidinium sp.2 및 미동정된 cyst of Peridinales 등이었다.

A study searching for unrecorded and taxonomically undescribed indigenous species has been conducted since 2006. Samples were collected from many sites in coastal waters and offshore in Korea as well as around Jeju Island. Since 2008 we have found 13 unrecorded species belonging to family Diplopsaliaceae, Heterocapsaceae, Kolkwitziellaceae, Protoperidiniaceae and Thoracosphaeraceae. The species are as follows, Preperidinium meunieri (2014), Heterocapsa ovata (2015), H. pseudotriquetra (2015), Diplopsalis lenticula (2008), Protoperidinium abei (2009), P. diabolus var. longipes (2010), P. depressum (synonym: P. parallelum (2008)), P. latispinum (2016), P. punctulatum (2010), P. solidicorne (synonym: P. spinosum (2010)), P. subpyriforme (2010), P. pacificum (2013), Scrippsiella hexapraecingula (2009) (note; The numbers in parenthesis refer to the year that the species was reported as unrecorded indigenous species by National Institute of Biological Resources, NIBR hereafter). Among these, 5 species were described as newly recorded species in Korean waters, and 8 were re-described in this study.
