Structure of ductus bursae+corpus bursae long (ca. 0.9 mm), weakly sclerotized; without distinction between ductus bursae and corpus bursae; corpus bursae formed by terminal elongate portion of ductus bursae, without signum.

Remarks. The species identification of the moths as P. teramni is stated by Vári himself.
Mine. An underside mine, tentiform, transparant, arbitrarily in disc, whitish on underside, no distinct folds visible, but mine strongly contracted. Fine black frass in one or two clusters; pupation without cocoon; pupa protrudes through lower epidermis before adult emerges; often more than one larva, up to six larvae found in one mine (Vári 1961: 225, De Prins & De Prins 2005: 369).
