Figs 11A–E
Diagnosis. Labrum as in Fig. 11A, SI seta simple; premandible ( Fig. 11B) with one apical and one inner tooth, and weak brush; antenna ( Fig. 11C) 5-segmented, with 3 rd segment subequal to 4 th, large LO, AR 1.2; mandible ( Fig. 11D) with 4 inner teeth; mentum ( Fig. 11E) with broad bifid median tooth, 4 lateral teeth (5 th vestigial or absent), with pale vertical “grooves”; VM plates small originating from 1 st lateral tooth; (abdomen missing).
Notes. The species is not typical in having a simple SI (usually serrated or divided), single apical tooth (usually two) on premandible and an overhanging abdominal segment 9, with the procerci directed posteriorly ( Cranston & Oliver 1988).
Ecology and habitat. As xylophagous species, larvae are wood miners ( Cranston & Oliver 1988, Saether 1983). Unlike Orthocladius (S.) lignicola larvae that were often encountered when sorting through the samples, larvae of this species were only found by detailed examinations of woody debris. Generally Chaetocladius species have a temperature preference of 6.6–9.3°C ( Rossaro 1991).
Sampling sites. Killarney and Arrowhead Provincial Parks and Muskoka District
Nearctic distribution. First published record for Canada: Ontario. USA: Oregon , North and South Carolina.
