Diagnosis.
This species has ochreous-buff forewings with veins somewhat highlighted with creamy white, and sparsely peppered dark brown scales, especially in the distal half. It is confusingly similar to several other
Coleophora
, especially among the seed-feeding groups and including several undescribed species (JFL pers. obs.) and can be recognized with certainty only through examination of the genitalia. In male genitalia, the tegumen is pyramidal, the gnathos ellipsoid and laterally compressed, the transtilla arms are markedly developed and outwardly upcurved, nearly joined medially, the apex of the sacculus has a few short dentate projections, the cucullus is broadly rounded, the valvula markedly sclerotized and digitiform, and the juxta rods each have one tooth, subapical on the right arm, medial on the left one; the overall configuration of the phallotheca with its long and curved outer tube, long, multi-coiled appendix, and long cluster of small, closely set cornuti, is very similar to that of several other seed-feeding species exemplified by
duplicis
Braun. (For genital terms of
Coleophora
, see
Landry & Wright 1993
.) In female genitalia, S8 is roundly trapezoidal with a notched posterior margin, the colliculum is as long as S8 with a blind sac at its anterior right extremity, the ductus bursae is very long with at least six coils in its anterior section, the spinulate section of the ductus is anteriorly curved and about as long as the membranous looped section, and the signum is double, one typical thorn-like with a short, stubby point, the other rasp-like and very small. This
type
of double signum is found in several seed-feeding species, such as the
duplicis
complex, with differences in size.

Note.
The
type
series of
C. cervinella
which consisted of
two females
was collected in a salt marsh (where several of the host plants of
atriplicis
occur). McDunnough suspected the synonymy of this species and wrote in an undated note placed in the CNC collection tray with the
type
: “Possibly falls to
atriplicis
descr. from Europe”. This species is undoubtedly more widely distributed than current records indicate but it is not recognizable without examining the genitalia. The occurrence on both the east and west coasts of North America as well as deep in the Okanagan valley of
British Columbia
and scattered localites in
Alberta
suggest that it could be Holarctic.
