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 — Not applicable. Ecology — Not applicable. Remarks — IRNP specimens from lichen zone pools. Specimens appear to be in the subgenus Pentapedilum (based on lack of frontal and cephalic tubercles, thoracic horn branching, segment eight spur, and lack of dorsal setae on anal lobe) and possibly near the epleri/tritum group, but subgenus and species cannot be determined with certainty using pupal exuviae morphology. Variation suggests more than one species may be represented.
