as discussed below. Tom Rickman, please change your database accordingly. Sorry for the trouble. Giving this one an accurate name was difficult. Thank you for the specimen. More examples (including a needed male) from your area would help secure the species determination.

not Lionepha disjuncta
This is not Lionepha disjuncta - it is not flat enough, and the elytral striae are not prominent enough, and it is not the right shape. Possibly Lionepha lindrothi but one can't identify it for sure based upon this photo.

 
Thank you David Maddison for your expertise.
Today I ran this single female specimen through the species identification key by Maddison & Sproul (2020) which appeared in a comprehensive review of the genus Lionepha. See https://bugguide.net/node/view/1786364.

Here are my external findings that take this specimen to L. lindrothi Maddison & Sproul, 2020:

Small (ABL 3.8 mm); elytra relatively convex (not flat); elytral striae weakly impressed (including the inner five); elytral microsculpture well impressed throughout with mesh cells stretched transversely to the ratio "feel" of 1.5:1; tibiae dark as the body.

It is probably not similar L. australerasa which has microsculpture more erased and pronotum not as rounded.

New species listings for Lionepha may be followed at the Post-2012 Registry of Nearctic Caraboidea. BugGuide images currently under "L. erasa" need to be restudied in light of the new review.
