49.160 Celypha rufana (Rufous Marble)
ws: 16-19mm (BTM, MBGBI5.2), fw 7.5-9.0mm (Sterling & Parsons); (May) Jun-Jul (Aug); tansy (Tanacetum vulgare), mugwort (Artemisia vulgaris); RDB in Wales and NW England and more recently found in Kent.
Celypha rufana §4 female
ID: Forewing finely reticulate with varying shades of brown, otherwise unmarked. Lacks the median fascia of C.striana. Similar to C.rosaceana which can usually be distinguished by its pinkish suffusion, but this fades with wear. C.rufana is also said to have a broader forewing than C.rosaceana (BTM).
Female genitalia: Illustrated in MBGBI5.2 (p344, f184) but this illustration is not very helpful as the peri-ostial sclerotisations are not drawn clearly and it shows the bursa copulatrix of C.rosaceana without a signum (it has one); shown at Moth Dissection, where insets simply (and unhelpfully) labelled "A" and "B" illustrate the difference in the peri-ostial sclerotisation between C.rufana and C.rosaceana. In C.rufana there is a long heavily sclerotised portion of introitus vaginae / ductus bursae extending from the ostium at the the posterior margin of the subgenital plate for ~2x the length of the subgenital plate and there are a pair of heavily sclerotised lateral arcs extending from the ostium to the posterior margin of the subgenital plate. In C.rosaceana the sclerotisation of the introitus vaginae does not extend beyond the subgenital plate and its posterior portion (extending from the ostium) has a poorly sclerotised wedge.
