Dear Peter, you can start with the following monographs and papers:

Péricart J. 1987. Hémiptères Nabidae d'Europe occidentale et du Maghreb. Faune de France, 71

Wagner E. & Weber H. 1964. Hétéroptères Miridae. Faune de France, 67

Carvalho J.C.M. 1955. Keys to the genera of Miridae of the world (Hemiptera). Boletim do Museu Paraense Emilio Goeldi, 11(2): 1-151.

Anyway, you have to find revisions of the different genera and group of species, asking for halp to specialists (such as Attilio Carapezza in Italy).

Regards,

Alessandro

Hi dear Peter

I think the journal: European Journal of Entomology will useful for you and this article:

1- Revision of Phaeochiton Kerzhner, 1964 (Heteroptera: Miridae: Phylini)

Fedor V. KONSTANTINOV.

ur. J. Entomol. 105 (4): 771-781, 2008 | 10.14411/eje.2008.102

2- http://www.aemnp.eu/PDF/50_1/50_1_33.pdf

3-Taxonomy and phylogeny of the Central European bug genus "Psallus" (Hemiptera, Miridae) and faunistics of the terrestrial Heteroptera of Basel and surroundings (Hemiptera) , http://edoc.unibas.ch/79/

good luck

I suggest, for starting, the same volumes proposed by A. Biscaccianti, published in the series "Faune de France". Another work could be: Stichel W., 1957, Illustrierte Bestimmungstabellen der Wanzen. Europa. (Hemiptera Heteroptera Europae), Berlin (in German Language). This is a less recent work, which probably needs some updates.  

With best regards,

Rinaldo Nicoli

Dear Kobor,

for a first approach, at least up to genus level, another work could be useful, even if not regarding specifically central Europe: "Tamanini L., 1989 - Tabelle per la determinazione dei più comuni Eterotteri italiani (Heteroptera). - Memorie della Società Entomologica Italiana, 67 (2) (1988), pp. 359-471". This work regards approx. two-thirds of Italian genera and one-third of Italian species, and it is carefully illustrated.

Best regards,

Rinaldo Nicoli

Dear Peter,

for Nabidae best is Péricart (1987): Hémiptères Nabidae in Faune de France 71

For Miridae best is Wagner (1952): Miridae in Tierwelt Deutschlands (1952) with corrections in Wagner (1967): Cimicomorpha also Tierwelt Deutschlands. Or if French is better for you: Wagner & Weber (1964): Miridae Faune de France 67. You'll have to check a waste amount of revisions afterwards or you need the help of a a specialist

For an overview I recommend the picture - CD of Gerhard strauss ("Corisa")  ([email protected])

Best regards,

Ralf Heckmann

Dear all!

Thank you for your answers, I hope that they'll be useful and I can ID my samples.

Best regards,

Peter

Hi, 

    Search for the long list of works of I Kerzhener for Nabidae, no one knew better the Nabids!

Thank you, Eduardo!

Dear Kobor,

for European Miridae (but principally for Mediterranean Region) there are also the following works by Wagner: Wagner E., Die Miridae Hahn, 1831, des Mittelmeerraumes und der Makaronesischen Inseln (Hemiptera, Heteroptera). Teil I, Teil II, Teil III, Entomol. Abh. Mus. Tierk. Dresden, 37 (Sup.),pp. 1-484; 39 (Sup.), pp. 1-421; 40 (Sup.), pp. 1-483. Wagner E. & Weber H.H., Die Miridae Hahn, 1831, des Mittelmeerraumes und der Makaronesischen Inseln (Hemiptera, Heteroptera). Nachtraege zu den Teilen 1-3.  Entomol. Abh. Mus. Tierk. Dresden, 42 (Sup.), pp. 1-96.

Best regards,

Rinaldo Nicoli

Dear All!

I've tried to wind up the publications you mentioned, but could not access any of them. If any of you has a digital copy of them would you be so kind to send it over? I would be extremely grateful!

Thanks,

Peter

Dear Pete,

attached you`ll find the first paper.

Best wishes,

Ralf

Dear Ralf!

Thank you, it helps a lot.

Best regards,

Peter

There is no key in these volumes, but a lot of information on ecology (host plant records etc.) and high-quality photos, and also the taxonomy is modern (in contrast to e.g. Wagner or especially Stichel; do not know Pericart that well, but he's not about Central Europe, as far as I understand):

http://www.amazon.de/Wanzen-Band-Cimicomorpha-Microphysidae-Flechtenwanzen/dp/3931374572

and

http://www.amazon.de/Wanzen-Band-Dipsocoromorpha-Leptopodomorpha-Cimicomorpha/dp/3931374491/ref=sr_1_fkmr1_1?ie=UTF8&qid=1447075384&sr=8-1-fkmr1&keywords=A.+Melber+%26+J.+Deckert%3A+Wanzen.+Band+1

Unfortunately, they are only available on old-fashioned paper, but all 5 Heteroptera volumes by the authors are highly recommended. If you use Wagner's key that was posted by Ralf Peter above and check it with the taxonomy etc. in Wachmann et al., you'll get exactly what you want.

Good luck,

V.

Thank you, Viktor!

Peter,

for Nabidae: what about a key of the Nabidae in Polish (Cmoluchowa Alicja, Klucze do oznaczania owadów Polski)? Although it does not include all species e.g. those of Prostemma), has a drawings of paramers. I use a rather old key for Nabidae of Kerzhner (but very good) - males and females are determinable safely according the drawings of genitals.  

With the key of Miridae is a greater problem - it is necessary to use a number of articles. Also it is possible to compare an "older" Wagner with 3(4) part a newer Miridae key of Wagner (Wagner, E. Die Miridae Hahn, 1831, des Mittelmeerraumes und der Makaronesischen Inseln (Hemiptera, Heteroptera)- but it is for all for the area around mediterranean Sea. In Polish there is a key for Isometopinae and Deraeocorinae (Gorczyca, Herczek, Klucze ..., 2002)

Magdalena Rohacova

Magdaléna,

Nabidae-problem seems to be solved because I've found that about this group there is an issue of Fauna Hungariae (Benedek P. 1969) which is quite accurate. Though the papers you mentioned will useful for sure.

Regarding Miridae I've started with Wagner which was uploaded in the answer of Ralf (see above), but I think that the comparison with other keys is necessary.

Summarized: thank you for your answer and I will look up the keys given by you!

B.r.

Peter Kóbor

Dear Peter,

I attached a key for Polish Nabidae, I know that problem with identification in this family seems to be solved, but maybe you will use this key to compare some facts, features or details :)

Best regards

Grzegorz

Dear Peter,

attached you'll find the Nabidae in Faune de France. It will help you!

In the females it's possible just to pull out the genital segment from the rest of the abdomen.

Best wishes,

Ralf

Dear Peter,

few answers before Magdaléna mentioned about polish keys to Isometopinae and Deraeocorinae. I attached this keys too. I think it will be helpful to you.

Best regards

Grzegorz

There is one more key to Phylinae among polish keys to subfamilies of Miridae.

I attached them in this answer (I could not attached two files)

Best regards

Grzegorz

Here is a new key for Nabidae:

Book Damsel bugs (Hemiptera: Heteroptera: Nabidae) of Poland: ide...

Best regards

Grzegorz
