Species g.  C. species algonquian.

Nearest neighbor Bin in BOLD database is BOLD:ADC3157
An unidentified species from British Columbia.

Adult: Some adults may be in the Sublette collection in the Museum of the University of Minnesota.

Male: Only a photograph of the male hypopygium is available (see below).
Anal point relatively broad.  About 12 setae in a large pale circle on tergite IX.  Superior volsella of D-type(e) of Strenzke (1959), Inferior volsella extends to just beyond the tip of the anal point, gonostylus narrowing relatively gentlyly over posterior third.

Male terminalia (left) and pupal spur (right) of C. species algonquian.

Pupa: caudolateral spur of segment VIII with about 3 spines (see figure above).

Fourth instar larva of the semi-reductus type, of medium size (fem. 12.9-14.0 mm; male 12.2-13 mm), lateral projections 170-250 µm).  Posterior pair of ventral tubules longer (ant. 0.78-1.15 mm; post. 1.1-3.25 mm), anal gills very long, 4-6 times longer than wide.  Gula dark and frontoclypeus also darkened.
Mentum (Fig.c) with pointed teeth, c1 tooth broad, c2 teeth moderately seperated but tend to continue edge line of centre tooth (type IB); 4th laterals markedly reduced (type III).
Ventromentum - VMR about 0.33-0.36. Pecten epipharyngis (Fig.a) with about 14 sharp, variable teeth (type D).

Cytology:  4 relatively short polytene chromosomes with the thummi arm combination AB, CD, EF, G.  Centromeres not noticeably heterochromatic.
Arm G relatively short, normally paired at ends, with a small median nucleolus that may be polymorphic and a Balbiani ring near one end.
Main nucleolus in arm E at 3f.  No inversion polymorphism in specimens examined.

Arm A1:    1a - 2c, 10 - 12, 3i - 2d, 9 - 4, 13 - 19                ie. as holomelas
Arm E1:    1 - 3e, 5 - 10b, 4 - 3f, 10c - 13                    ie. as aberratus
Arm F1:   

Found:  Ontario - Bat Lake (45.577°N, 78.523°W), Algonquin Park, Nipissing Co.; Frontenac Provincial Park, Sydenham (44.5178°N, 76.5394°W)(BOLD).
