Figs 14A–F
Diagnosis. Head yellowish brown; SI seta bifid; pecten epipharyngis consisting of 3 equal sized scales; premandible ( Fig. 14A) with single narrow tooth, without brush; antenna ( Fig. 14B) AR 1.7; mandible ( Fig. 14C) weakly rugose on outer margin; mentum ( Fig. 14D) with broad median tooth, about 2.5x as wide as 1 st lateral tooth which are broadly rounded apically, 2 nd lateral reduced, slightly set off from 3 rd lateral; VM plates with lightly sclerotized basal extension; body with long thick setal tufts ( Fig. 14E); posterior end of abdomen as in Fig. 14F, anal tubules, cylindrical about 0.75x as long as posterior parapods.
Notes. There exists some uncertainty regarding the identity of C. (C.) annulator and its separation from the Nearctic species Cricotopus (Cricotopus) slossonae Malloch and Cricotopus (Cricotopus) varipes Coquillett ( Epler 2001) .
Ecology and habitat. Some larvae within the complex have temperature preference of 17 °C and tolerance range of 10.7–23.6 °C ( Rossaro 1991). Some larvae within the complex occur in high elevations (i.e.> 2000m) found over boulders of cold streams, to the soft sediments of the lower reaches of streams and lake outlets ( Sublette et al. 1998). Some species within the complex are univoltine ( Tokeshi 1986).
Sampling sites. Massasauga, Arrowhead and Algonquin Provincial Parks and Parry Sound District.
Nearctic distribution. Canada: Ontario.
