Maccaffertium
I am very in favour of Maccaffertium but as a subimago and not knowing the size makes it to difficult to go near species. However based on the wood grain that puts the size around 8 mm, by the forewings matching Lewis 1974 b, 156, and abdomen matching 143, this is all very suggestive of pulchellum. Lewis 1974 b, has that species in your area too.

Change your title to Maccaffertium

I was a cabinet maker so I am very familiar with wood grain size.
