Group F: Forewing with longitudinal pale streaks
without oblique pale streaks
12 Species, two of which are extinct
All of the extant species can be identified on external features. |
|
1. Species with a distinctive antenna
1a. Upper surface of antenna clothed in long fuscous scales from base for at least ½ its length; apical region white > 37.109 Coleophora wockeella
A large species; pale streaks limited to costal and plical; discal streak may or may not be present; veins marked with ferruginous scales. 1b. Antenna white with its upper surface clothed in pale ochreous scales from base for ⅖ of its length
> 37.060 Coleophora ochrea Dorsal, plical and discal, but not costal, pale streaks are present; oblique streaks are present but are ochreous-brown 1c. Antenna black with a white apex > 37.045 Coleophora chalcogrammella
Small species; ♂has an additional white ring on one or two segments at ¾ |
1d Antenna white, unringed, scape with a long tuft
Both these species have a yellowish ground colour and broad, bold, (subcostal, discal, plical and dorsal) white streaks. They also differ in size, though there is some overlap. 1di Brown wedge between subcostal and discal streaks about as broad as the subcostal streak > 37.058 Coleophora conspicuella 1dii Brown wedge between subcostal and discal streaks at least twice as broad as the subcostal streak > 37.059 Coleophora vibicella The extinct C.vibicigerella would also key here; it would be distinguishable by having a broad white costal (rather than subcostal) streak and by its smaller size. |
The remaining species have the antenna white ringed fuscous either to the apex or fading towards the apex.
2. Forewing brown. Costal streak dominant; plical streak narrower but prominent; discal streak weak or absent
2a Forewing colour at apex very dark brown
> 37.042 Coleophora saturatella (Forewing ochreous to brown at apex)
2b Outer aspect of hindtibia brown with a white median line > 37.044 Coleophora discordella 2c Outer aspect of hindtibia white with an ochreous line (where??) > 37.041 Coleophora genistae |
If C.vulnerariae were extant it would need genital dissection to distinguish it from C.albicosta.
Male: In C.albicosta a small spinous process from the lateral end of the sacculus projects posteriorly beyond the margin of the sacculus; in C.vulnerariae a shorter tooth in a similar position does not cross the saccular margin.
Female: Ostium broad; spiculation of posterior half of ductus bursae sparse in C.albicosta; narrow and dense respectively in C.vulnerariae.
(No images of female C.vulnerariae at Moth Dissection, illustration in MBGBI3 shows a quadrate ostial plate in C.albicosta, elongate in C.vulnerariae - but it is actually clearly elongate in C.albicosta)
