- [The interest of the works on Nematinae of Muche, is that all of the European species (at the date of the draftings) are quoted, besides those of Central Europe of whom it gives keys, but also those who are localized outside the Central Europe and whose it gives the geographical location.]

[The use of the Key of Berland 1947 leads to errors of determination]
----------
* Determination of sub-Family Nematinae (with radial Cell not divided), see :
* Determination of Genus (sensu Prous & ali) of West Palaearctic
- A Genus created (after the work of Muche 1974) by Lacourt can be confused with a Nematus, that is Dinematus with apex of Clypeus truncated straight.
- Our capture (see the photo of Clypeus) does not belong to this Genus.
- - Other Characteristics of our capture :
- Tibiae 3 with a longitudinal furrow (see photo).
Forewings with 3 radial Cells closed [if 2 radial Cells (Vein 2r-m absent) then Euura (pars)].
* Determination of species (with key of Muche 1974)
- - Characteristics of our capture :
- Stigma of Forewings pale with a brownish spot.
Tibiae 3 blackish.
- [To help the determination, I added the photo of the apex of the Abdomen (the shape of the Sawsheat & the length of its hairs are important criteria for the Nematinae)].
tibialis was also captured in Italy
