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 — Larvae in genus generally occur in moss, hygropetric areas, acidic streams and areas near springs. Remarks — One IRNP specimen from a lichen zone pool. Specimen does not match any described exuviae, but pupae of many species remain unknown. Appears to match “virgatus group”, which is distinct enough that it may warrant subgeneric status. Notable traits include lack of oral spines on tergites, caudal spines present on all tergites and sternites except segment one (with longest spines on tergites two, seven, and eight), sternite three with a distinctive medial patch of elongate and thin spines, anal segments with three robust spines about 12-17 μm long, no anal macrosetae, and total length about 2 mm.
