20 July 2008, The Netherlands, Havelte.
On small path, in the sun.

I see a lot of M. cing.ulatus, but this one was larger (20-22 mm). Or is it perhaps an other genus?

Hi Klaas,

I think it is a Machimus arthriticus. Do you have more pictures of this specimen?

Greetings, Danny Wolff

Hi Danny,

I have 4 pictures, but more or less from the same point of view.
What info do you need for an id?

Thorax
I think some spines of scutelum broke off.
(Probably there have been 6 spines, 4 pale ones in the middle and a smaller one at each side. Or it is just 4 spines)

Hi Klaas,

yes, now it is clear that it is M. arthriticus. The very brown coloured wings and wing veins confused me a little bit. But the short spine-like hairs on the humeri ("shoulders"; other Machimus have fine hairs) and the spines on the underside of the front femora together with the colour of the legs are good characters.

Greetings, Danny Wolff
