The ectal end of the duct terminates in an inconspicuous nephropore anterior to the ventral chaetae in the originating segment, without forming a distinct vesicle.

Both areas became completely dry prior to our 2008/2009 collections, suggesting this species may require a dry period in order to complete its life cycle.

was not present in several earlier collections at the swamp site, suggesting a very patchy distribution. Additional immature worms collected at other sites are provisionally assigned to this species, based on the relatively long proboscis and nephridia in VIII and IX.
