Preparations of genitalia: 5 3, 2 Ƥ.

Description & Diagnosis. Wingspan 24–26 mm, in general smaller than the externally similar L. farinata which also occurs in Turkey. Forewings a little narrower than those of farinata , greyish white, without discal dot, grey underneath, with the basal and central area brown. Hindwings on upper- and underside like forewings ( Fig. 23 ). Male genitalia ( Fig. 49 ) similar to those in L. griseata griseata , with short sclerotized costa with weakly marked distal tip (not a free process like in farinata and coassata ), differing in the much larger harpe with a pointed, tooth-like apex and the longer dorsal arm.Juxta in L. ancyrana vase-shaped, nearly two times longer than in L. griseata griseata . Saccus much shorter than in farinata , but longer compared to griseata ; aedaegous longer and more distinctly curved compared to griseata ( Figs 47 –53).

Bionomics. Collected in May and June at 1400m.

Distribution. Turkey (Map 5). May also occur in W. Iran.
