Figs 35A–E

Diagnosis. Head capsule without tubercles; Labrum and premandible as in Fig. 35A; SI seta bifid; premandible with single apical tooth, brush very weak; antenna ( Fig. 35B) 5-segmented, AR 1.1–1.2; mandible ( Fig. 35C) with shorter apical tooth, about as long as combined length of distal two inner teeth; mentum ( Fig. 35D) with bifid median tooth without accessory tooth and 5 lateral teeth; VM plates (see Fig. 35D) elongate, tapering to a broad truncated base, with indication of a posterior lightly sclerotized extension; long beard consisting of 12–13 setae; posterior end of abdomen as in Fig. 35E; procercus with small posterior spur, 5 apical setae; anal tubules short conical; posterior parapod short, as long as width at the base, some claws with sharply angled teeth.

Notes. Larva generally agrees with Saether’s (1985: 97) species description, although, there was no mention of a spur on the procercus.

Ecology and habitat. Larvae of this species are shredders and occur in high numbers in leaf litter.

Sampling sites. We found the larvae inhabiting streams in all the provincial parks and districts located in our study area.

Nearctic distribution. Canada: Alberta, Ontario. USA: North Carolina, Ohio, South Carolina, Tennessee .
