Figs 27, 28 Etymology: The species is named in honour of Jurgen Lenz, a German lepidopterist who lives and works in Zimbabwe , and actively collecting Alucitidae and Pterophoridae . Diagnosis: Externally, this new species is distinguished from all congeners by the dark (almost black) colour of the wings, and by the double pectinate antennae. In the male genitalia it is similar to M. antennatus in the shape of the saccus, gnathos and aedeagus, but can be easily distinguished by the shape of the anellus (its branches are widened towards the apex in the new species but are parallel-sided in M. antennatus ) and the valves (supplementary appendages are developed at the very base in the new species, whereas they are situated above the base in M. antennatus ). Description: Male . External characteristics: Head, thorax and tegulae dark grey, almost black. Labial palpi also dark, very long, more than 5× as long as eye diameter.Antennae dark brown, double pectinate. Wingspan 12–17 mm ( holotype , 17). Forewings dark brown, almost black. In distal part of wing all blades have a slanted, light grey, narrow band. Towards middle of wing, where splitting of blades ends, is a black contrasting band perpendicular to wing. Tops of all six blades of forewing terminated by distinct black spots. Hindwings plain, dark brown. Legs yellow. Figs 27, 28.
