Group C: Identification from male genitalia
1. Median lobe of gnathos exceptionally broad and notched > 37.066 Coleophora laricella
nb: Specimens of C.salicorniae that bypassed identification in the C.clypeiferella vs C.salicorniae section would key here. It has a small sacculus with a short spine projecting posteriorly.
3. Sacculus small and triangular with a distinct anterolateral projection
3a Sacculus with a small posterolateral projection and a concave lateral margin
> 37.015 Coleophora serratella 3b Sacculus without a posterolateral projection; ventral* margin fairly straight; cornutus at level of base of tunica > 37.014 Coleophora coracipennella 3c Sacculus without a posterolateral projection; ventral* margin somewhat sinuate; cornutus in vesica anterior to tunica > 37.017 Coleophora prunifoliae * It is almost impossible to lay the sacculi open in these species, but if they were laid open the ventral margin would become anterior. |

5. Sacculus with a posterolateral projection and a concave lateral margin
5a Lateral margin of sacculus deeply notched between anterior and posterior projections; sacculus about as broad as valvula > 37.100 Coleophora solitariella
5b Lateral margin of sacculus shallowly concave between a small projection at the anterolateral angle and a longer projection at the posterolateral angle; sacculus much broader than valvula > 37.040 Coleophora lithargyrinella
5b Lateral margin of sacculus shallowly concave between a small projection at the anterolateral angle and a longer projection at the posterolateral angle; sacculus much broader than valvula > 37.040 Coleophora lithargyrinella
6. Sacculus with a distinct anterolateral angle, lateral margin fairly straight, terminating in a small posterolateral projection > 37.024 Coleophora vitisella
|
8. Sacculus with a convex anterolateral margin, without a distinct anterolateral angle or projection and ending laterally or posterolaterally bluntly or in a pointed projection
8a Multiple short blunt spines on inner surface of sacculi > 37.005 Coleophora lutipennella
8b Posterolateral point projecting posteriorly; valvula ~twice breadth of sacculus > 37.013 Coleophora siccifolia

8c Posterolateral point projecting posteriorly; apex of aedeagus serrate ventrally > 37.023 Coleophora idaeella
8d Lateral point projecting laterally; apex of aedeagus smooth > 37.025 Coleophora glitzella
8e Sacculus blunt or slightly pointed; apex of aedeagus very acute; very small species (fw 2.5-4mm) > 37.028 Coleophora juncicolella
8f Sacculus blunt; aedeagus with many small spines at apex > 37.022 Coleophora lusciniaepennella
8g Valvula projecting well beyond sacculus (valvular projection beyond apex of sacculus almost ½ length of sacculus) > 37.029 Coleophora orbitella
8h Valvula projecting only a little beyond sacculus (valvular projection beyond apex of sacculus ¼ to ⅓ length of sacculus > 3 species with identical genitalia
8f Sacculus blunt; aedeagus with many small spines at apex > 37.022 Coleophora lusciniaepennella
8g Valvula projecting well beyond sacculus (valvular projection beyond apex of sacculus almost ½ length of sacculus) > 37.029 Coleophora orbitella
8h Valvula projecting only a little beyond sacculus (valvular projection beyond apex of sacculus ¼ to ⅓ length of sacculus > 3 species with identical genitalia
