a. Prominent long sclerotised"tail" clearly visible from ostium for posterior ½ of ductus bursae, (due to) relatively sparse circumferential spiculation, ostial plate quadrate
ai. Ostium posterior from a large "U"-shaped incision in posterior margin; signum small > 37.063 Coleophora albicosta aii. Ostium posterior from a shallow "U"-shaped incision in posterior margin; signum large > 37.0567 Coleophora coronillae aiii. Ostium anterior and exceptionally broad > 37.070 Coleophora tamesis In all other species in B6 dense circumferential or bilinear spiculation at least partially conceals any "tail"-type sclerotisation running through it
|
b. "Tail" very short or absent anterior to long bilinear/ flanked linear densely spiculate section; ostial plate transverse; incision in posterior margin almost reaches anterior margin; signum medium-sized
bi. Posterior margin slightly produced either side of notch > 37.058 Coleophora conspicuella bii. Posterior margin unadorned > 37.025 Coleophora glitzella |
c. Ostial plate clearly broader at anterior margin than at posterior margin (~2-3x); ostium central; signum fairly large
ci. Anterior margin of ostium strongly sclerotised; anterior margin ~2x width of posterior margin
> 37.042 Coleophora saturatella cii. Anterior margin of ostium no more strongly sclerotised than rest of ostial plate; anterior margin ~3x width of posterior margin > 37.061 Coleophora lixella & 37.062 Coleophora tricolor (these seem to be inseparable) |
d. Ostial plate transverse; ostium posterior
di. Ostium "U"-shaped from an incision in posterior margin extending halfway to the anterior margin; "tail" quite short > 37.041 Coleophora genistae dii. Ostium "V"-shaped, a shallow notch in posterior margin, "tail" long > 37.107 Coleophora clypeiferella |
e. Ostial plate quadrate; ostium central
ei. Anterior apophyses shorter than ostial plate; posterior margin deeply incised
> 37.059 Coleophora vibicella eii. Anterior apophyses longer than ostial plate; posterior margin notched but not incised > 37.033 Coleophora trifolii & 37.035 Coleophora alcyonipennella Although externally inseperable from C.frischella the female genitalia of C.alyonipennella may be inseparable from those of C.trifolii |
f. Ostial plate elongate; ostium anterior > 37.034 Coleophora frischella
