Holotype ♁ [ Ukraine ]: the Crimea , Yalta , Nikita ( Nikitskiy ) botanical garden, 20.V.1981 , leg. Vasilyeva (ZIN). Diagnosis . Ectoedemia similigena is very similar to E. turbidella and cannot be distinguished by external characters on the basis of the little material studied. The male genitalia have a distinctly longer valval tip than turbidella , and the gnathos is much narrower. Th e female genitalia have the posterior apophyses not reaching beyond the anterior ones and the signa are distinctly wider. Partial redescription. Male forewing length ca. 3.0 mm, antennal segments 55. Female forewing length 2.6 mm, antenna broken. Specimens too much worn or broken for detailed description, similar to E. turbidella , overall paler. Male genitalia (Figs 24–26). Capsule length 325 µm . Tegumen produced into widely rounded pseuduncus. Gnathos with central element narrowly triangular, smooth. Valva length 215 µm , in ventral view with almost parallel sides, evenly curved towards demarcated, inwards curved tip, pointed and cut off at end. Aedeagus 365 ♁µm long, very long (1.12 × capsule length) and stout, with two pairs of prominent
