I went through the keys but I find difference among the two females posted here (22 mm and 19 mm): the elytral apices, median spot at suture, basal pattern on elytra, pronotum are little different from s. grisator (18 mm male and female, below).
 
Are these diff or the same S. grisator? |

Actually, these spms are known under S. grisator indeed.
I believe that nobody has already seen the type in Copenhagen. A picture is very welcome.

In my opinion, beetles imitating barks show a morphological variability of body structures much greater than ones imitating other insects (e.g. Clytini) or having aposematic (=warning) coloration (e.g. Trachyderini, Pyresthini).
In other words, the same species may show different structures, while different species might have converging coloration. |

Here a link to a picture of S. grisator Fab., but not the type.
It seems the same species than your pictures 3 and 4.
Pattern of 1 & 2 look a little bit different, but the problem is "what is S. grisator Fab. ?? " |
