11. Limnodrilus amblysetus Brinkhurst et al., 1990

( Fig. 1H )

Limnodrilus amblysetus Brinkhurst et al., 1990: 910 .

Limnodrilus silvani Eisen, 1879:19 ; Liang, 1987: 196.

Material examined. One individual was collected from Bureun­myeon, Ganghwa­gun , Incheon, E: 126°31′ 38.89″ N: 37°39′51.10″, 7 April 2013 (collector: Jung J). This specimen was mounted on a slide and deposited at NIBR ( KOSPIV0000216811 ) .

Remarks. L. amblysetus has chaetae, all of which are bifid or bluntly simple-pointed ( Fig. 1H ), and the nodulus of anterior chaetae is located at a slightly proximal position ( Brinkhurst et al., 1990). Our specimen agrees well with the description of Brinkhurst et al. (1990).

World distribution. North America, China, Japan.
