a. Spiculate section without an anterior tail; Ostium posterior from an incision in posterior margin
ai. Ostium extremely wide (>½ diameter of ostial plate); incision in posterior margin of ostial plate extremely wide (>½ diameter of posterior margin)
> 37.066 Coleophora laricella
> 37.066 Coleophora laricella
aii. Ostium "U"-shaped; posterolateral angle of ostial plate rounded; signum large with a semicircular base plate and a long spike
>37.027 Coleophora potentillae
>37.027 Coleophora potentillae
aiii. Ostium "V"-shaped from a broad notch in posterior margin; signum medium with a small base plate > 37.036 Coleophora conyzae
b. Spiculate section without an anterior tail; Ostium central from an incision in posterior margin;
bi. Posterior margin of ostial plate narrower than anterior margin (~2:3); signum medium-sized
> 37.056 Coleophora serpylletorum Posterior margin of ostial plate about same length as anterior margin; signum large in remaining species in section H4b
|
bii. Signum with a semicircular base plate and medium-length curved spike (shorter than width of base plate) > 37.026 Coleophora violacea
biii. Signum with a fairly flat base plate and medium-length curved spike (shorter than width of base plate); ostium with an anterior pouch
> 37.021 Coleophora arctostaphyli
biv. Signum with a fairly flat base plate and a long, fairly straight spike (as long as the width of the base plate) > 37.031 Coleophora ahenella
c. Spiculate section with an anterior sclerotised tail
ci. Ostium diamond-shaped in posterior half of ostial plate; introitus strongly sclerotised, broad and broadest near anterior margin > 37.104 Coleophora adspersella
Remaining species in section H4c are all very similar. They all have a short anterior apophyses; the ostium varies in detail but in all it involves the posterior margin; sclerotisation of the anterior margin of the ostium is continuous with a tapered introitus and a tail than runs through and anterior to any spiculate section. |
cii. Ostial plate only slightly transverse; posterolateral margin rounded; signum with narrow base plate (spike longer than width of base plate) > 37.051 Coleophora kuehnella
In all remaining species in this section the ostial plate is very transverse and the signum has a broader base plate (spike not longer than width of base plate)
|
ciii. Ostium from a "V"-shaped notch occupying ¼-⅕ of the posterior margin; posterior margin otherwise straight and forms a ~90° angle with lateral margins; anterior margin of ostium not or not obviously pouched
ciii𝝰. Anterior apophyses shorter than ostial plate > 37.052 Coleophora ibipennella ciiiβ. Anterior apophyses about same length as ostial plate > 37.053 Coleophora betulella |
civ. Sclerotised tail not or hardly obscured by spicules
civ𝝰. Anterior margin of ostium obviously pouched; very few spicules > 37.054 Coleophora currucipennella civβ. Anterior margin of ostium only a little pouched; spicules present > 37.055 Coleophora pyrrhulipennella |
cv. Sclerotised tail at least partially covered by dense spicules; anteroventral margin of ostium obviously pouched; ostium~⅓ diameter of ostial plate
cv𝝰. Posterior margin of ostial plate forms a slightly obtuse angle with lateral margins > 37.049 Coleophora anatipennella cvβ. Posterolateral angles of ostial plate somewhat rounded > 37.050 Coleophora albidella |
