looks funny; suspect a fancy staph or rather an agyrtid

Deinopteroloma
It's an omaliine staph, Deinopteroloma - I think probably D. pictum. The other species, D. subcostatum, has a lot of punctures between the two elytral striae closest to the elytral suture on each elytron. This specimen seems to lack that, but the image is a bit fuzzy in that region. Both are pretty widespread from California to British Columbia, and subcostatum gets up to Alaska. The species were originally placed in Anthobium, then Moore described a new genus Mathrilaeum, for them but it turned out that they are (relatively) close to some Asian species that had been described much earlier from Burma under the name Deinopteroloma. Smetana has described more Asian species (see American Beetles, vol. 1, p. 339). (This is in the tribe Anthophagini of the subfamily Omaliinae.)

 
DId the image get replaced?
This is pretty clearly D. subcostatum - the numerous punctures next to the sutural stria are now visible. Compare to the new photo of D. pictum.

 
Yes it did...
quite a while ago..it's definitely of the same specimen.

 
thank you, Dr. Thayer, for your prompt & detailed comment
