These keys
owe a lot to the work of
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.
