This specimen was mounted on a slide and deposited at NIBR ; KOSPIV0000216891 . Remarks. According to Timm (2009) , this species has 2­6 chaetae with slightly longer, thinner and straighter upper tooth in anterior ventral bundles ( Fig. 1L ), the penial sheaths of this species look funnel shaped with thin walled.
