Hello AdYRuicanescu,

in my opinion is this Trachys problematicus. Trachys fragariae has no hairs on the elytra and pronotum!

Penso proprio che Tomasius abbia ragione. Non è T. fragariae.

The hairs are not visible if I don't use a diffuser. So when I made the identification, some years ago, I didn't know about the trick with the diffuser. I have to agree with Tomasius about the T. fragariae. But I have other T. problematica also here: viewtopic.php?f=73&t=21960 and it differs in shape. The front is not so concave between the eyes and the body shape is more oval.
I like this collaboration and I seem to learn more here than in my all single activity. Thank you.
Cheers.

You're right, it looks a little bit different to Trachys problematica. Another possibility is Trachys ahenata Mulsant & Rey, 1863, but I don't know this species very well, so I can not say without any doubt if it is.

Yes you're right. I see here: http://coleoptera.ksib.pl/search.php?ta ... en&dds=par Trachys pumila Illiger, 1803 (synonym with T. ahenata Mulsant & Rey, 1863). Unfortunately, the single guide I have in Trachys is Schaefer, 1948. - Les Buprestides de France. It should be very productive if someone of us can make a guide of European Trachys and Habroloma. I think they are not so many species.

Be careful, Trachys ahenata isn't synonymised with Trachys pumila! After Löbl & Smetana (2006) is Trachys ahenata a valid species. The southern balcan species "Trachys pumila" lives in Phlomis sp.

Well, this will make it harder then. Because they are 3 species with a similar habitus. I have the books (Schaefer, Curletti, Bily, Muhle & co. Lobl & Smetana) at my job, I will check where I found T. ahenata synonymised to T. pumila. I have only my database "Buprom" here

The Trachys pumila-group is very difficult, because there exist a few species wich names are not correct identified. Also Trachys phlyctenoides is after Löbl & Smetana a valid species.
Fact is, that your specimens are not the southern balcan "Trachys pumila" wich lives in Phlomis sp., thats why I wouldn't call it Trachys pumila.

Certainly not these ones I collected in Transylvania, far enough for the Southern Balkans.

Now I am confused because I have not a new guide.
