Silvanidae - Ahasverus advena

Size: 2.7mm
This appears to be a new one for my backyard. Hope I got it to the correct family. After that, Cryptophagus seems likely, and if I'm running D&A's key correctly, C. valens Casey seems to be a possible determination. From what little I can tell on the web, C. valens might be an invasive import (but D&A doesn't read that way). Corrections welcome :)
