Thanks to gomphus who indicated me an forgetting as regards the color of the Thorax of the .
Accordingly I have rectified.
---------
Besides, For the :
- I deleted the coloring of Femora 2 useless for the identification.
- Only the coloring of Knees 1 (not all the Femur) is useful for the identification.
=============================================
The 2 insects captured in the same place and practically at the same time, in Cne : Pontoise (Dépt. Val-d’Oise) - 15 VI 2002
--------
Biblio (main) :
- Haris 2000 : in “Folia Entomologica Hungarica, LXI - p.95/148" - Study on the Palaearctic Dolerus ...
- Muche 1969 : ... Dolerini ... in “Entomologische Abhandlungen - Band 36 Supplement - p.72/94"
======
Determination of sub-Family Dolerinae, see :
Eyes are in shape short oval (length / width << 2)
Thus, they are Dolerus

- Wings hyaline
- Tergits without transverse sculpture
- Tergits entirely orange, except the Tergit 1
- Apex of longer setae of Cerci is at the same level as the apex of longer setae of Sawsheat (see photo)
- Apical setae of Sawsheat clearly apically curved towards the inside (see photo)
    [the drawing the most exact of setae of Sawsheat is given by Muche]
*** Of where the determination [aericeps = bajulus]

******
- Head in dorsal view behind the eyes parallel or narrowing
- Ratio (Length of Antennae / Length of Abdomen) :
.... Ratio of our capture = 0.87 [if not, Ratio = about 1-ε]
- Thorax entirely black (include Pronotum & Tegulae)
- Wings hyaline or almost hyaline
- Knees 1 orange
- Femora 3 black
- Tibiae orange (Tibia 3 : except 1/3 apical black)
- Tergits smooth (without sculpture)
