The new species resembles superficially solely the rather remote species Xenonola limbata (Plate 2, Figs 5, 6 ; gen. figs 11, 12) due to the unusual and in Hampsonola unique forewing pattern, the extensive blackish inner part of the forewing, but the two species differ in several details of the forewing shape and markings. The most conspicuous differences, besides a number of fine differences in the wing pattern, are the much broader forewing and more expanded blackish part of the wing reaching the tornus in H. diehli , while the blackish forewing area is shorter in X. limbata , being terminated at the proximal two-thirds of ventral margin There are no other similar species known in Meganola or in any Eurasian noline genus. The male genitalia of the new species display, surprisingly, a closer relationship with H. indistincta (Hampson, 1894) (gen. figs 8, 9), according to the following distinctive features: H. diehli has conspicuously shorter, apically rounded uncus (that of H. indistincta much longer, apically pointed), somewhat thicker tegumen without process ( H. indistincta has rounded, finger-like process on tegumen), narrower, apically less dilated dorsal and considerably shorter ventral lobe of valva; similarly shaped, but medially less bent harpe; much shorter, broadly rounded vinculum (it has triangular apical process in H. indistincta ); the configuration of the aedeagus is practically identical in both species.
