Aegomorphus wojtylai Hilszczanski and Bystrowski, 2005
Previously, this species was mistakenly confused with A. clavipes; in fact, in addition to coloration, it clearly differs in the structure of the male genitalia. The range is similar to that of A. clavipes, but apparently A. wojtylai is somewhat more northern-most likely absent in the Caucasus, etc. (although the southern boundary is not yet clear). In Russia, it is found from the western borders to Primorye. The biology is similar to that of clavipes, where beetles are caught together on the same forage trees.
Male - Orenburg region, female-Altai.

Thanks for the info...
I didn't even know about the new species... ahem, interesting.
and what are the clear taxonomic differences between one and the other (except for genitalia), what exactly is in the color-bandages or what??

In color-it is the bandages that are the key point, but still males often have to be opened - there are also lighter wojtylai, darker clavipes...
And some females are one hundred percent distinguishable so far and generally do not work.

I wonder what exactly happened to the bandages? the base of the elytra is darker?

As a non-expert on egomorphus, it seems to me that the upper row is voltilae, and the lower clavipes, except for the last one smile.gif

Intresno, who catches egomorphs how? I just haven't caught it yet. They say it's coming to light. Where else and when to collect it?

This is the first time I've heard about catching these barbels in the light, and, to put it mildly, I doubt that this is the case . Here, in the Yaroslavl region, from the second decade of June to the very end of July, Aedomophis can be collected on the trunks of old poplars and aspens (often together with Xylotrechus rusticus). It is quite difficult to detect, you have to look closely: the beetle perfectly imitates the color of the bark of forage trees. But it is sometimes found in the mass.

in the spring, it is well cut down from the same poplars and oaks. it pupates under the bark.

I totally agree with KGD, the top one is clavipes, the other three are papal (although the last one is not so unambiguous). The lower row is almost certainly all clavipes, judging by the color and shape of the body (as can be seen from the pictures, in wojtylai the elytra are more parallel, they are not as flat and extended in the shoulders as in clavipes).
By the way, Aegomorphus never caught the light (although I have quite a lot of them), but where does the information come from? Something really hard to believe.
Beetles are best collected during the day on freshly cut birches, poplars, aspens, oaks, bird cherry, etc.

"Beetles are best collected during the day on freshly sawn "
How long to wait after I cut them? tongue.gif

A friend who caught them in the Caucasus told me about fishing for light. Maybe I got the view mixed up, I'll check again.

19.02.2007 16:31, Archypus

KDG, Cerambyx, you have confirmed my suspicions about 2, 3, 4. The bandages are clearly more pronounced, the bases of the n / wings are very darkened. 2 and 3 have a brown color. Unfortunately 2 and 3 females. Does this mean that I can't be 100% sure that this is wojtylai?

2 and 3 were collected in a log cabin of gray alders, 4 flew on a freshly cut birch; clavipes from dead poplars and aspens, 8 flew through the window of a Moscow apartment smile.gifEverything else was told by Dmitrich. When in danger, beetles often bend their legs and fall into the grass.

I think at the expense of the 2nd and 3rd beetles you can be quite sure yes.gif

Dear Colleagues,
Because I feel much better in English I will stay with that language. I understand most of Russian from your conversation (Have experience using Russian keys mainly for parasitoids). I am impresseed by your ability for determination of Aegomorphus. I fully agree with KDG and Cerambyx that numbers 2,3 and most probably 4 is A. wojtylai, the rest are clavipes.
I would be interested in your experience with rearing and type of galleries by wojtylai to compare with clavipes. In Poland I have reared it only from Quercus, but I saw specimens from Mongolia reared from Betula. Galleries of wojtylai are here much different than clavipes ones. A. wojtylai larvae penerate deep into wood while clavipes feed under the bark and only pupate sometimes shallowly in the wood.

With all the best, Jacek Hilszczanski

Hello Jacek!
Nice to see You here, my respect to fellow entomologist.
I believe that the talk in Russian above leads us to the conclusion of both A. wojtylai and A. clavipes share the same host wood-plants, but the character You've stated for the larvae regarding the allocation into wood is also noted here.
I would believe that specialists who dealt with cerambicidae, lamiinae in particular, will comment this in more details.

I have heard that recently Aegomorphus wojtylai Hilszczanski and Bystrowski, 2005 was reduced by M. Danilevsky to synonyms of A. obscurior (Pic, 1904), but I have not seen the article. Can one of our respected cerambycidologists comment on this situation?

Here is my contribution to this topic: Aegomorphus clavipes Schrank, 1781 (male). I sometimes come across a beetle on aspen logs in the Moscow region. This instance was caught: 11.06.2000. (Moscow region, Balashikha district, okr. der. Poltevo).
Re: Today I decided to add a female from the same place.

I don't know if I agree or not, because I didn't study the taxonomy of this group. I think the experts know better.

Corrected the name to match the currently accepted one. Thank you for the correction.
