Diagnosis and Notes

Very similar in appearance to C. stigma. The female AR is 1.02-1.1; the SD 3,6-10 (and differing from stigma of which the SD is 3,8-10). The spermatheca is spherical, with a short diverticulum.
The figure of the genitalia is taken from Glukhova (1989) and of the spermatheca from Kremer (1966); the wing does not appear to have been illustrated, but is described as being almost identical to that of C. stigma.
