37.072 Coleophora otidipennella (Wood-rush Case-bearer)
ws: 10-13mm; May-Jun; field wood-rush (Luzula campestris), heath wood-rush (Luzula multiflora); common throughout Britain
ID: Group G - forewing streaked with oblique stripes to costa, without scattered fuscous scales > 25 species
Female genitalia: Ductus bursae (DB) with a spiculate section immediately adjacent to subgenital plate (SGP); incision in posterior margin (PM) of SGP extending less than 1/2 length of SGP; introitus vaginae not sclerotised; incision in PM broad, ostium a slit with sclerotised edges at anterior margin of SGP, signum moderate, scobinate section of DB anterior to spiculate section.
Male genitalia: Currently keyed as - sacculus with a smoothly rounded anterolateral angle (but it does appear slightly angulate); sacculus without a posterolateral process; sacculus with finely crenulate lateral margin (but the most posterior of these crenulations is the largest and could be interpreted as a process); tunica of aedeagus very short, several cornuti in vesica. (Key probably needs some revision)
