Hmm, considering:
- we can't see clearly any of the most important features used when keying parasitica (propodeum; face; surface texture & carinae on the thorax and gaster) and
- parasitica are notorious for being both subtly variable in colour AND looking very similar and
- Gavin Broad & Matt Reidel both won't even commit to tribe, let alone to genus
... all suggests my pessimism was well founded!

Pessimism was founded............ non,.le realism is founded! ?
?Matt has just re-examined my Coelichneumon, I wonder sometimes if we use the same keys or the same decriptions............ moi and others arrivont not with the same species! ?
?Even Horstmann gives up helping me for this group! ?
?I believe that the difficulties of this group, the dispersed literature...........le makes that much publishes anything believing to control the subject, all that complicates the revision! ?
?But especially, the opinions of those which never published on this group are painful! ?
?For let us ichneumons, one is still at the stage to re-examine the types......... when they are found! ?
?That made several hundreds of species which change name or are red?crites per annum! ?
?To go to throw a glance on TAXAPAD of Yu, you will include/understand, it makes the synthesis of knowledge of this group on a world level! ?

Certainly, finding literature is one of the most serious problems when studying parasitica. Then when you find a key you often find it is 50 years old and has been superceeded by many name changes and additional species - all written-up in individual papers published in different countries, in different languages!

That is why all keys should be published on the internet within a wikipedia like project... Publishing keys in written form is quite contraproductive.
The nicest example of the problems associated with the current system is that of the Eastern-Palearctic region, where three very different cultures (Chinese, Japanese, Russian) meet, each with very different language and writing. Also the countries hava relationship far from being friendly, which has restricted communication even further. Furthermore, the use of English is far from general in any of these countries.

he problem is still much more serious than you think it! ?
?Not badly of species for lack of communication, described in the Eastern European countries are already described and put gradually in synonymy! ?
?To open the wikipedia................with all those which think that to make a key...........des recent work is simple coming from Bulgaria introduced a crowd of species which also should be downgraded! ?
?Moreover all reliable European specialists from go away! ?
?It is simpler to go to describe faunas of the Latin America, of Australia, or India or North Africa that of the probl?mes of European fauna and one has less of literature to compare and especially less contradictors! ?

Dear Camille,
at present I am in Munich. Here I have discussed the photograph with Erich Diller. We do not know which species is figured, but it is not Pristiceros infractorius.
Sorry, we have tried your best.
Best wishes,
Kees
Zwakhals!

Just received this -
From Dr. Martin Schwarz via Gavin Broad
Dear Gavin,
The mystery wasp is a male of Ischnus inquisitorius. This species is very
variable in coloration.

And yes, the perfect enigma.................une dozen synonyms. ?
?It passes from Ichneumoninae to Cryptinae, and in various tribes and it is not sure that it will remain there!
?
?However common in Europe!
