Group G: Forewing with longitudinal and oblique pale streaks without scattered fuscous scales
21 Species
In all these species short oblique streaks run between the discal streak and the costa in the apical ⅔ of the forewing.
All except C.pennella are some shade of ochreous in colour and only in C.pennella is size helpful in identification.
6 of them can be identified on external features (if we ignore the possibility of C.calycotomella).
Note that MBGBI3 describes many of these species as white with coloured streaks, but in my opinion they all appear coloured with white streaks with the exception of C.pennella and perhaps to a lesser extent C.currucipennella.

Species that may be looked for here but are keyed in other groups
C.pyrrhulipennella (Group F) may show a few white scales in the position of oblique streaks.
C.argentula, C.artemisicolella and C.versurella (Group H) usually have scattered fuscous scales but these may be few in number and overlooked

1. Forewing predominantly white > 37.065 Coleophora pennella
Scape not tufted; forewing >7mm, slightly falcate at apex; antenna white, spotted black on underside
Scape not tufted; forewing >7mm, slightly falcate at apex; antenna white, spotted black on underside
2. Antenna white, unbarred, scape tufted > 37.056 Coleophora serpylletorum
|
3. No subcostal streak
3a Scape with a long tuft; antenna ringed fuscous
> 37.054 Coleophora currucipennella The coloured oblique streaks may be substantially more fuscous than the longitudinal streaks and this marking with fuscous scales may cause the specimen to be looked for in Group H. 3b Scape not tufted; forewing <7mm, not falcate at apex; antenna variable, often almost entirely white or indistinctly ringed
> 37.038 Coleophora lineolea In specimens of C.lineolea with a more distinctly ringed antenna, external features may not provide sufficient confidence of identity - it is also keyed from the genitalia. |
4. Discal and plical streaks each divided longitudinally by a fine ochreous line; antenna white, dotted black on underside in ♀
> 37.036 Coleophora conyzae 37.037 Coleophora calycotomella also keys here
Male genitalia are shown at Moth Dissection and differ from those of C.conyzae. Note that 37.095 C.trochilella may show a division in the plical streak only; it has antennae ringed to the apex.
|
5. Antenna white with such indistinct ochreous bars that it appears entirely white above, spotted blackish below > 37.070 Coleophora tamesis
As the forewing is very similar to the remaining species in this group and the antennal features somewhat variable, this species is also keyed from the genitalia
|
All other species in Group G have a white antenna ringed or barred to the apex or with the rings/bars fading towards the apex
All show a pale subcostal streak (though in some species all streaks are a little obscure). They are very similar.
The remaining species require genital determination.
