Diagnosis. Dorsal surface of head ( Fig. 48A) coarsely granular without tubercles; cephalic S3-seta ( Fig. 48B) plumose; labrum as in Fig. 48C; labral lamella pectinate quadrate plate; SI seta comb-like on inner side with bases contiguous; premandible bifid, with distinct brush; antenna ( Fig. 48D) 5-segmented with large triangular spur on apex of pedestal, 2 nd segment short with petiolate LO and blade reaching the tip of segment 5, AR 1.2; mandible with pale dorsal tooth and two dark inner teeth; mentum ( Fig. 48E) with single pale median tooth about as wide as the 2 nd lateral; VM plate fan-shaped, widely separated, with not striated band along anterior margin; posterior end of abdomen as in Fig. 48F; procercus large, directed posteriorly, with 6 distally branched apical setae; supraanal seta with basal spines; anal tubules short, conical.
Notes. This species appears to be the same as C. sp. B in Epler (2001) and C. sp. 2 in Oliver et al. (1978). The larvae build portable horn-shaped sand cases ( Fig. 48G).
Ecology and habitat. Larvae were found in riffle and pools of headwater streams typically occurred among the woody debris of study streams. This species was found sympatrically with Micropsectra in all habitats sampled. Larvae have been recorded in small cool mountain streams ( Hudson et al. 1990).
Sampling sites. Little White River, Arrowhead and Algonquin Provincial Parks.
Nearctic distribution. Canada: Ontario, Northwest Territories. USA: Ohio, Alabama .
