Biblio :

- Muche 1974 : ... Nematus ... in “Deutsche Entomologische Zeitschrift - N.F. Band 21 - p.1/34”
    [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)].
Thus Nematus.
    We can add to the diagnosis of the Genus (see on the photos) :
    ... Claws bifurcate.
    ... Mandibles basally abruptly broadened.
* Determination of species (with key of Muche 1974)
    - Characteristics of our capture :
      Stigma of Forewings pale without a brownish spot (see photo of Imago)
      Frontal pad (green curve drawn on the photo) unbroken.
      Body pale, orange, +/- red.
      Sawsheat (in dorsal view) with edges almost parallel (see photo).
      Head not broadened behind Eyes (see photo).
      Thorax pale & orange, with only 2 black spots.
      Antennal segment 3 shorter than the segment 4 (see photo).
Thus miliaris (= capreae in Muche )

miliaris was also captured in Italy
