The male genitalia of the three species are very similar in type (see the Figs 14-21), the new species (Figs 14-17) can be distinguished fromM. longicornis (Figs 18-19) by its weaker but slightly longer uncus, more rounded fultura inferior, more arcuated valva, longer cucullus, shorter and basally remarkably broader harpe, different carina and differently shaped and sclerotized field of vesica, without distal dilatation. Comparing with those of M. antherici (Figs 20-21), M. leily has slenderer, distally not so extended uncus, slenderer valva, slightly longer cucullus and basally broader, thicker harpe. Figs 16-21. 16 = Metopodicha leily sp. n., paratype, genital capsula, 17 = Metopodicha leily sp. n., paratype, aedeagus, 18 = M. longicornis BOURSIN, 1957, male genital capsula, 19 = M. longicornis BOURSIN, 1957, aedeagus, 20 = M. antherici CHRISTOPH, 1884, male genital capsula, 21 = M. antherici CHRISTOPH, 1884, aedeagus
