Metanarsia moroccana sp. nov. is described from Eastern Morocco. The species is remarkable in having an unmodified recurved labial palpus and the adults active in October. Adults and male genitalia of the new species are illustrated, and the adults compared with the most superficially similar Metanarsia dahurica Bidzilya, 2005. An annotated list of the species of Metanarsia is provided.
As a result of the first revision (
This contribution is devoted to the description of an additional new species from Morocco. The species can be easily recognized superficially by its reddish brown forewing in combination with a recurved labial palpus. The presence of these two characters in the newly described species is unique in Metanarsia: other species of the genus with similar forewing pattern have straight labial palpus, whereas species with recurved palpus differ in the colour of the forewing. Additionally, M. moroccana sp. nov. seems to be an obligatory autumnal species whose adults fly in October, uniquely among Metanarsia. An annotated list of species of Metanarsia, updated according to taxonomic changes proposed in the last few decades, is provided.
Male genitalia were dissected and spread using standard methods (
Pinned specimens and details of external morphology were photographed with a Canon EOS 5DSR DSLR camera attached to an Olympus SZX12 stereomicroscope. Slide-mounted genitalia were photographed with a Canon EOS 600D DSLR camera mounted on an Olympus U-CTR30-2 trinocular head mounted on a Carl Zeiss compound microscope. For each photographed specimen, sets of 10–20 images were taken at different focal planes and focus-stacked using Helicon Focus 6 with the final image edited further in Adobe Photoshop CS5.
The material examined is deposited in Staatliches Museum für Naturkunde Stuttgart, Germany (SMNS).

The monophyly of Metanarsia is still unconfirmed. A combination of a very short ductus bursae and extremely long corpus bursae without a signum was considered as an autapomorphy of the genus (
It is obvious that additional species of Metanarsia will be described when more samples have been sequenced (
