First Record of Six Marine Ciliate Species of Genus Strombidium (Ciliophora: Spirotricha: Oligotrichia) from Korea with Ecological Notes

Abstract

To supply the morphological and ecological information of oligotrich ciliates in Korea, water samples were seasonally collected in Gwangyang Bay and Jinhae Bay from August, 2010 to February, 2012 and processed by quantitative protargol staining method. As a result, six species belonging to the genus Strombidium Claparede and Lachmann, 1859 are identified: Strombidium emergens Kahl, 1932; S. datum Lynn et al., 1988; S. epidemum Lynn et al., 1988; S. tressum Lynn et al., 1988; S. bilobum Lynn and Gilron, 1993; S. pollostomum Lynn and Gilron, 1993. These six species were newly reported from Korean coastal waters. Strombidium emergens is a middle sized Strombidium (20-50 [mu]m in length) and has open and deep oral groove to girdle portion. Strombidium dalum is a small sized Strombidium (
