Ectoedemia (Ectoedemia) turbidella (Zeller)

Figs 21–23, 27–28

Diagnosis. Externally E. turbidella cannot be distinguished from E. albida or E. similigena, although these two are generally paler. Th e male genitalia are characterised by the short demarcated valval tip, the relatively longer aedeagus (1.22–1.27 × capsule length) and triangular gnathos (Figs 21–23). Female genitalia have prominent widened posterior apophyses, reaching beyond anterior ones and very short and narrow signa (5–6 cells wide, 2.7–5.1 × as long as wide) (Figs 27–28). For differences from hannoverella see diagnosis of that species (Van Nieukerken 1985).

Biology. Hostplants: Populus alba L. and P. canescens (Aiton.) Sm., never on saplings. Univoltine, larvae from September to November, adults fly from April to June.
