3rd version :
I deleted the comparisons between pm & mj, because there are exceptions for the Xoridinae which do not allow to generalize.
Of where this 3rd version.
-----
2nd version :
I had based the determination of P.(Calliclisis) on 2 photos of species a priori well determined, in fact they were not her (The 2 photos disappeared of the Net) !
The shape of the nervures observed on photos, thus did not characterize the Calliclisis.
Of where this 2nd version.

These keys owe a lot to the work of Gavin Broad (The key concerns only Great Britain)
    They also take into account genera & species absent in Great Britain.

Thanks for F. di Giovanni (Eopteryx) who allowed me to improve the table of Keys of genera & sub-genera.

Fundamental characteristics of Poemeniinae & Xoridinae :
- Forewings with vein 2m-cu present
- Head sub-spherical (obvious character, more or less obvious for some other Ichneumonidae)
- Poemeniinae (excluded Pseudorhyssa) :
    Epicnemial carina entirely absent.
- Pseudorhyssa (sub-family Poemeniinae) :
    Mesoscutum with conspicuous transverse rugae & Epicnemial carina present.
- Xoridinae :
    Mesoscutum without transverse rugae & Epicnemial carina present.

There is obviously other numerous Ichneumonidae which also possess these caracteristics, thus let us see the determination of the 2 sub-families object of the present message.

Good work JP, just some points:

1. Ischnoceros can be easily distinguished from the other Xoridinae for the presence of a frontal horn.

2. You forgot the poemenine genus Cnastis, which has wrinkled temples (as Neoxorides and Podoschistus) and a tooth on tarsal claw I and II (Neoxorides has tarsal claws simple - Podoschistus has teeth on tarsal claws 1-2-3). Here the description of the european C.bulgaricus: A Review of the Genus Cnastis TOWNES and a Key to the Palearctic Species - Linzer biologische Beitrage 28/1: 231-236

http://www.landesmuseum.at/pdf_frei_rem ... 1-0236.pdf

I send you a mp

Filippo

Saluti,

Thank you for your observations.

For the genus Ischnoceros, Thank you for this fundamental precision,
I am probably going to modify my key, when I can it.

For the genus Cnastis, I had referred to FE (who does not quote it) and to Townes (which quoted it for only Eastern Europe and Japan). I had not thus verified with Taxapad !
I think (as what takes place for certain other genera or species) that we shall not capture Cnastis to the West of Bulgaria.
However I will how see integrating this genus into my key.

Ciao.
D & JP Balmer
