Caro Claudio. For me it is a beautiful maschio of Dorcadion ( Pedestredorcadion ) veluchense ( Pic, 1903 )

Hi Collegues!

They can be Dorcadion taborskyi Heyrovsky, 1941
but I see D.veluchense similar as following specimen:
http://www.zin.ru/animalia/coleoptera/rus/pedestdn.htm - D.veluchense - (last line) det.Danilevsky
http://www.biolib.cz/en/taxonimage/id101628/ D.veluchense

It belong to group II: ossae-taborskyi-veluchense

Stripes are divided [1] so it can be rather D.taborskyi:

Dorcadion (Cribridorcadion) taborskyi Heyrovsky, 1941
D. lianokladii Breuning 1962
D. margheritae Breuning 1964
D. joanninae Breuning 1967
D. wewalkai Breuning 1974

(four times described by Breuning as different species (1962-1974!)

According Pesarini Sabbadini 2007 this species distributed widely:
nomo Grevena: 4 km a Sud-Ovest di Krania; n. Joanninà: Milia, Metsovo,
Passo Kataras (loc. typ. di D. margheritae); n. Trikala: Koridallos, Piniada; n.
Karditsa: M. Karava; Ftiotide: Domokos, Stilida, M. Eta (loc. typ. di D. taborskyi),
Paliuri (in vicinanza del loc. typ. di D. Iianokladii), Makrakomi (in vicinanza del
loc. typ. di D. wewalkai); Focide: Kastelli, Elikonas.

Attribute [1] - taborskyi
[2] - divided stripes can be taborskyi and veluchense
[3] - interesting detail. Pesarini Sabbadini clear:

"Quanto alla superficiale somiglianza con D. veluchense, con il quale D.taborskyi coabita al Passo Kataras e sulle pendici del M. Karava nel Pindo centrale, la distinzione delle due specie è del tutto agevole in base alla conformazione della
fascia suturale, normalmente conformata in D. taborskyi e sostituita in D. veluchense da un paio di fasce presuturali fortemente accostate alla sutura, che di regola è priva di fascia, anche se talora presenta una fascia sottilissima".

D.taborskyi is variable species. Determination need confirm. Regards

Jacek, it cant be taborskyi for sure . And taborskyi aint really very variable - have seen/collected/revised them hundreads from many places...

Btw, taborskyi belongs to ossae group and veluchense to septemlineatum group which is characteristic with 7 stripes ( 2 extra sutural bands ). I have seen a few taborsky with something what looked like these 2 extra sutural bands, but they were almost invisible and much slimer and most in females what is characteristic for all Pedestredorcadion group. And there is still difference in body shape.



P.S. Zin.ru and Danilevsky co are absolutely useless with connection to European species of Dorcadions !

1.

Do you suppose that it is not D.veluchense >> http://www.zin.ru/animalia/coleoptera/images/d004.jpg


"D.veluchense" det.Danilevsky is very similar as "ours" strange specimens from first post.

I agree with You that it can be D.veluchense - perhaps m.peristericum BREUNING, 1946 (it was my first idea... )



Moreover Pesarini & Sabbadini 2007 p.73, key:



and here will be taborskyi...

Zdeno, have you (or did you see) the same D.veluchense as Dorcadion of Claudio?

Regards!

Good morning Jacek. I will try to reply on your questions.

- first photo is definitely something from septemlineatum group : septemlineatum vs veluchense. Collecting datas are needed.
- citate from Andrea`s and Carlo`s work about that presutural band : I respect these guys very much. They are my teachers, but nobody is 100% perfect. " presuturale band unbroken for septemlineatum group " : thats not always right !
- yes, I have seen veluchense with " broken band "...a few collected by myself ( later will do photo for you ) and f.e. 1 is here : http://www.biolib.cz/en/taxonimage/id101628/. Im going there again in 2 weeks time - esp. for these...

Septemlineatum group is characteristic, like I said before, with 2 extra sutural bands, which hasnt got any other specie in Greece. Sp septemlineatum has both, well, all bands much wider and veluchense slimer. And body shape. "septemlineatum " - they look like you stud up on them , much wider body.

My opinion...maybe I m wrong...if you want to be 100% sure, send that photo to Andrea and Carlo...

Thank You! I agree with yours opinion!

Ancora nessuns determinazione ?
