The present study was conducted to research some Actinosporeans species in Oligochaetes (Branchiura sowerbyi). From April to May, 2004, Oligochaetes were sampled from the Daewi Reservoir located in Kunsan, Jeonbuk and a drainageway of the fish farm located in Wanju, Jeonbuk. Tow species of Actinosporeans not reported yet in Korea, Raabeia sp. and Triactinomyxon sp., were detected from Oligochaetes. Actinosporeans detected are recorded to Raabeia sp. E and Triactinomyxon sp. F. A total of 200 Oligochaetes were investigated from two sites, and 28 individuals (14%) were found infected: 27 individuals (13.5%) with Raabeia sp. E and one individual (0.5%) with Triactinomyxon sp. F.
