Hello! Can you help me identify the bug? Chisinau neighborhood, May 2, 2018. Thank you in advance!

It's a pity that no one knows my bug... still.

Southern border of the North Taiga subzone.

On the basis of foresters, near the sawmill.

Is it Monochamus urussovi or Monochamus sutor? Is it possible to determine the gender?

Good day everyone!
Dear forumchane, experts, help, please, in determining these bronzes.
The only thing I know is that they're from Africa.

Hi!
The date is April 5.
Yekaterinburg.
Is it possible to determine the beetle's family, genus, species, and sex from these images? Dermestidae?
Length 3 mm.
In a wooden building, in a heated room caught.

Megatoma tianshanica (like her), male

Only in the Reference Book that identifies quarantines... the shape of the mace is not very similar. I also tried to understand what it is (URL 31340), but I didn't find out (some people think that M. graeseri, others that M. tianshanica)

I identified them as graeseri, but I was convinced that it was tianshanica.

What morphological features should be recorded on the image to accurately determine the species?

The mace of the male's antennae is clearly visible in the photo. I'd like to see some more genitals. And it is better to send a copy/copies (I'm not sure about the photo) Jiri Hawe

Khava's name is Yura. Or am I missing something?
