Forum Entomologi Italiani

Dear colleagues.
Who can help in the accurate identification of the beetle?
Protaetia (Netocia) sp.

asiatica

Hello Zdeno.
No, it's not Protaetia (Netocia) asiatica.
I made ​​a comparison with N. asiatica of my collection and look at the literature .
It is similar to N. asiatica, but differ in structure mesothorax and habitus. In addition, its elytra not have a characteristic sculpture from N. asiatica.
I have a suspicion that it is possible Netocia hungarica armeniaca f.. tristicula
For comparison, here are photos of a typical Netocia asiatica f. asiatica (Armenia, Gegharkoonik, Gavar distr. 18.05.2013)

Hmmmm. With these images, to my mind, this is P. asiatica, I agree with Zdeno.

The elytras are very different from ungarica's ones... Can you make a better foto ?

The mesosternal process seems to be very close to asiatica's one...

What are the differences you noticed ?

Regards,

Stéphane

Tigran, I have collected specimens like yours - almost completely back in Aragatz. I have a feeling, that these black ones are just old worn specimens. I have also compared aedeagus with the classic ones ( white patches ) from around Khosrov and it matches the specimens from Aragatz...
+ hard to say from this photo, but from around Vedi ( ca 20km N ) I have 1 completely black funebris...it looks different a bit that this one, but the angle can mislead...

Dear Stéphane
I made ​​a comparison with a series of P. asiatica and with a series of P. hungarica armeniaca,
From P. asiatica this beetle has the following features.
1 A narrower habitus
2 On the elytra virtually absent familiar to P. asiatica ribs (elytra almost smooth).
3 Pigidium more elongation will.
4 Pronotum shaped like a typical P.asiatica, but it is more convex. This differs not only from P. asiatica.
5 lug mesothorax without hairs, its upper edge projecting more than the asiatiki points on it larger.
I will make a few more photos for comparison.

Regards, Tigran.

Zdeno typical coloring for P.asiatika f. typica such. With white pattern.
This is why I brought the picture of a typical P.asiatica for comparison with beetle of Goris.
Too your P. funebris funebris. Absolutly black P. funebris are often caught in the lower reaches of Armenia. It's called P. funebris funebris f. geghardica

Aethiessa?

Dear Marco.
No, it is not Aethiessia.
In Armenia living one species Aethiessia mesopotamica rugipennis.
Well Aethiessia m. rugipennis different other Cetoniinae structure of the hind legs and trim.
Furthermore, the hairs on the lower side of the body at A. mesopotamica rugipennis always black.

Hi,

I found the "global look" different from P. ungarica armeniaca (more elongate, upper face without the typical "sweet" aspect, ...)
It seems that there are some ribs on the last middle part of elytras with some white places no ?
The lake of setae can be explained by the fact it seems to be an old specimen (which is confirmed by the very attenuated thorns on anterior tibias).
Have you found other specimens like this one ?

Thaks Stefane.
If we take into account the structure of the hind tibia, they are in many respects similar to the shins P. hungarica armeniaca.
Regarding the habit. Large P. hungarica armanica also have a narrow habit.
This beetle of course "worn".
Its main difference from P. hungarica armeniaca, this structure of the pronotum. it is convex and round.
However, the dimple on elytra resembles to elytra P. hungarica armanica
White spots are not constantly sign. In P. hungarica armanica they too are available in some instances.
On the other hand, I venture to suggest that it is possible to black aberration P. hungarica armaniaca (f. tristicula) or P.ignisternum?.
For yet, this beetle in a single number and a female.

I would be very happy if someone from the members of the forum posted photos P. hungarica armeniaca f. tristicula.

For comparison, I will lay of photos to series P. hungarica armeniaca from Armenia.

Dear Colleagues,
(who are interested).
In all likelihood, this beetle is P. (Netocia) aethiessina !
Thanks very much for help Bogdan Vasko.

Bogdan knows very well the Cetoniidae of these regions, so if he said aethiessina, I can't say anything else. Thanks for his help !

Yes, Mr. Bogdan drew my attention to a few interesting details.
The question of membership of this instance is not completely resolved course.
But I am also inclined to think that this P. aethiessina

Fortunately, I managed to find some males are very similar to my beetle from my colleague, whom he gathered in the same place where I caught my beetle. I hope that soon question the species of this beetle is allowed of course.
