Oggetto del messaggio:  Virgichneumon digrammus (Grav. 1820) ♀ - Ichneumonidae - Ichneumoninae - Oxypygi (sensu Wesmael)

Capture in the garden remained uncultivated of our house - Cne Donzy (Départ. Nièvre - France) - 17 IX 2010
=======
Biblio :
- Perkins 1960 : RES - Handbooks ... Ichneumonoidea … Vol VII (2aii)
- Berthoumieu 1894/1897 : Ichneumonides d'Europe et des pays limitrophes
- Constantineanu 1959 : in "Fauna RPR - Vol. IX - Fasc. 4", ... Tribul Ichneumoninae Stenopneusticae" (in Rumanian)
- Schmiedeknecht 1906/1908 : in "Opuscula Entomologica" - Part 1/6 (p.1/413)
---------
Our capture is a ♀, because there are 6 visible Sternits (see the photo), the ♂ having 8 visible Sternits.
---
The Abdomen is apically acute and the apex of last Sternit is distant from apex of Abdomen
Thus our capture is an Ichneumoninae, an Oxypygi Wesmael
-----
The criteria allowing to identify the capture are :
- The Antennae are semi-ringed with white
- The Scutellum is ivory
- The Coxae 3 have not Scopa (see the photo)
- Femora & Tibiae are reddish (except the apex of Tibiae 3 blackish)
- Postpetiole closely punctuate (but badly visible on our photo)
- Tergits entirely black, except the last one ivory

We obtain, after a lot (...) of stages, the identification.
---
digrammus was also captured in Italy
=====
NB - this sp. is :
- Barichneumon for Perkins
- Melanichneumon nudicoxa for Constantineanu
- Ichneumon balearicus & nudicoxa for Schmiedeknecht
