37.108 Coleophora salicorniae (Glasswort Case-bearer)
ws: 12-14mm; Jul-Aug; glasswort (Salicornia spp); saltmarsh on English coasts from Cornwall to Yorkshire, N&S Wales.
Coleophora salicorniae §1 male
ID: Forewing plain, unicolorous, not white, without white markings, not metallic; antenna ringed fuscous to apex, basal segments thickened with buff scales > C.clypeiferella/salicorniae both of which may show one or two forewing stigmata.
The thickening of the antennal flagellum is for 2 segments in male and to 1/4 in female C.salicorniae and to 1/6 in both sexes of C.clypeiferella.
C.clypeiferella is distinct in having the first abdominal tergite strongly sclerotised in the form of a shield with two rows of stout peg-like spines.
Male genitalia: in C.salicorniae the anterolateral angle of the sacculus is produced into a broad rounded process, while the postero-lateral angle bears a narrow pointed process; the uncus also appears distinctive in being produced into a pointed/beaked apex; the tegumen in both species is very long but in salicorniae it is distinctly narrowed before the attachment to the uncus; the prongs of the aedeagus are untoothed.
In C.clypeiferella the lateral margin of the sacculus is drawn into a point, but there is no distinct anterior or posterioir process; the uncus is rounded at the apex; the tegumen remains broad to the point of attachment of the uncus; the prongs of the aedeagus each has a broad-based tooth.
