Larva of the semireductus-type.

Cytology: 4 chromosomes with the thummi arm combination: AB, CD, EF, G.
Specific sequences of North American populations not described.  Arm E should have a distinctive sequence, and there should be a nucleolus in arm C.
murA:
murE1:    1 - 3e, 4, 10b - 5, 11 - 10c, 3f, 12 - 13
murF:

Found: Alberta - Amisk Lake.

            European specimens in deep sediments.

Molecular Data:
The mtCOI and CytB and the Gb2β sequences for a European specimen are in GenBank (and the COI sequence is also in BOLD)

Identified by P. Michailova (Dinsmore & Prepas 1997, p. 2171).  Kiknadze (pers. comm.) found none in a small sample she checked from Amisk Lake.  Sæther (2012) lists this material as C. entis.
If correctly identified, this means C. muratensis would be a Holarctic species.
