Specimen(s) collected during a study of coastal rock pools of Lake Superior at Isle Royale. Two shoreline zones were differentiated using a line between upslope “lichen zone” pools and downslope “splash zone” pools. See citation for details. Distribution — Widespread in Nearctic, including many southeastern U.S. states. Ecology — Swiftly flowing water, in gelatinous tubes with sand grains incorporated. Northern and montane streams, lakes, and pools, and streams in southern localities. Remarks — IRNP specimens from splash zone pools. This is the only described Nearctic Synorthocladius species, though an additional undescribed species has been suggested based on reared adults.
