Remarks. Caradja compared his new species with Agonopterix angelicella (Hübner, [1813]) , seen as a having the same external appearance, only more delicate. Also, in his description, Caradja points out the lack of the dark rings on the apical joint of palpi, this character excludes conspecifity with A. archangelicella ( Caradja, 1920) . Hannemann examined Caradja’s type and dissected its genitalia ( Fig. 16) but left no comments on it, making us believe that he did not noticed the features that clearly indicates belonging of this specimen to another genus Exaeretia . Furthermore, the external appearance and genital structures of the species Exaeretia amurella Lvovsky, 1990 described much later correspond to those of D. exquisitella Caradja. The small differences in the external appearance and the shape of upper outgrowth of cuiller in the male genitalia structures are probably within the frame of individual variability.
