a. Ostium entirely posterior
ai. Densely spiculate section without an anterior tail > 37.089 Coleophora pappiferella
Ostium from a narrow "V"-shaped notch in posterior margin; spiculate section about as long as anterior apophyses Densely spiculate section has an anterior tail in remaining species in H3

aii. Midline sclerotisation of introitus apparent behind ostial plate
Ostium from a shallow notch at posterior margin; introitus narrow and broadest near posterior margin > 37.069 Coleophora caespititiella aiii. Introitus not noticeably sclerotised; posterolateral margin of ostial plate rounded, posterior margin produced around a "V"-shaped ostial notch > 37.108 Coleophora salicorniae

b. Ostium anterior or anterocentral
bi. Densely spiculate section without an anterior tail
bi𝝰. Ostium central its anterior margin broadly strongly sclerotised; spiculate section shorter than ostial plate+anterior apophyses > 37.060 Coleophora ochrea biβ. Ostium anterior, tear-drop-shaped from a narrow incision in the posterior margin (so narrow that the sides touch); spiculate section longer than ostial plate + anterior apophyses > 37.071 Coleophora glaucicolella
