Hello dear forum!
I'm new here, and if you don't mind, will post some grasshoppers from time to time hoping for your help in determination

Here's the first one I took in my country (Georgia, Tbilisi, 31.07.2016). The image is clickable.



Best regards,
Armen

Hi Armen

Welcome to our Orthoptera forum! Of course, we help whenever we can

The one on the picture is Euchorthippus pulvinatus, male

Best regards

Hi Florin!
Thank's a lot for you help I wasn't sure about the determination. The only Euchortippus species I've found mentioned for Georgia was Euchorthippus transcaucasicus (a pity, there are no pics I could compare with), so is it possible that instead of mentioned Euchorthippus pulvinatus it's a Euchorthippus transcaucasicus male?

Here's the link on the local Acrididae checklist (not sure if it's complete) http://biodiversity-georgia.net/index.p ... =Acrididae

Hi Armen

Thanks for this hint. I haven't studied the Orthoptera fauna of Georgia before. But I recently got some unpublished notes from Dragan Chobanov where only Euchorthippus pulvinatus is mentioned.

I quickly checked the original description. It's quite old and shows no usefull drawings. But Euchorthippus transcaucasicus seem to look similar to Euchorthippus pulvinatus. If I have time I'll check some literature but probably not before next week.

All the best
Florin

I'm not in a hurry, Florin, and will wait for your conclusion as long as it takes!
Until then I'll post another topic

Sincerely,
Armen

But it's more fun to study your picture than to do what I should

In the old book about Grasshoppers of the U.S.S.R I found a key including Euchorthippus transcaucasicus. It seems realy to be this E. transcaucasicus on your pic. Do you know Euchorthippus pulvinatus? One difference is bodysize: Euchorthippus transcaucasicus is bigger. On the picture it's only possible to recognize that the specimen seems to be stronger than a "standard" Euchorthippus pulvinatus.

But also coloration and the foveola looks like it is described in the key for Euchorthippus transcaucasicus.

All the best
Florin

Well, that's great! It means, that it's the first pic of a live specimen on the internet
No, I'm not familiar with E. pulvinatus, but the specimen on pic was not smaller than an average Oedipoda coerulescens male (they were sitting side by side, so I managed to compare them).

So, should we call it Euchorthippus transcaucasicus or Euchorthippus cf. transcaucasicus?
