Corynoneura sp. C Epler

Figs 12A–C

Diagnosis. Generally small size, less than 4mm; head capsule with finely granulose dorsal surface, no sculpturing evident; antenna ( Fig. 12A) 4-segmented, total length 1.8x the length of head, basal segment 302 µm long, 3 rd segment darkened, AR 1.1; mandible with three inner teeth; mentum ( Fig. 12B) with three median teeth, central one about one third the size of outer pair, 5 lateral teeth, 1 st lateral slightly smaller than 2 nd lateral; subbasal setae ( Fig. 12C) with lateral spinules arising along most of the main shaft, lightly sclerotized ring around socket.

Notes. Our single larva, keyed to Corynonura sp. C in Epler (2001).

Ecology and habitat. Larvae of Corynoneura are found in both lentic and lotic habitats and in fast flowing waters are often found in fissures in submerged stones ( Cranston et al. 1983). In this study of headwater streams, they occurred mainly in riffles. Most species of Corynoneura are bivoltine with extended emergence from July to late October and a smaller emergence in December ( Coffman 1973).

Sampling sites. Algonquin and Massasauga Provincial Parks and Muskoka District.

Nearctic distribution. Canada: Ontario. USA: North and South Carolina.
