Diagnosis.
North American specimens have brownish grey forewings with a discal black chevron-like mark and a distally adjacent dirty white spot. They are very similar both in maculation and genitalia to the Nearctic
gelidella
(Busck)
, which is also reported to feed primarily on willow (
Hodges 1974
). The similarity in pattern between the two was noted by
Clarke (1941)
. The male genitalia of both species has the digitiform process of the sacculus straight, relatively thick, apically rounded and extended to about three-quarters the height of the valva, and the cucullus of the valva is broadly rounded; differences between the two species appear subtle and have not been studied. In the female genitalia of
conterminella
, the signum is near the posterior third of the corpus bursae or near the constriction of the ductus bursae, whereas in
gelidella
it is in the anterior third of the corpus bursae; as in male genitalia, differences are subtle and have not been studied in relation to individual variation. The two species are more than 5% barcode divergent.

Note.
The three North American records were collected in relatively remote locations and probably indicate that the species is native, hence Holarctic in distribution. The very close similarity in morphology with the North American
gelidella
means that the two species would be very difficult to distinguish without the help of barcodes, and there could be unrecognized specimens of
conterminella
among
gelidella
material in collections.
