Ilybius biguttulus (Germar)
Based on a combination of diagnostic characters: shallow emargination of the terminal segment, body size, and relatively broad metasternal wing. Most similar to eastern I. incarinatus and I. confusus but can be separated by metasternal wing width (narrower in the other 2 species) and elytral sculpture (need scope to confirm). Thanks for the nice detailed images!

Female
Due to emarginate terminal abdominal segment. Possible to get an enlargement of that region? It may get it to species...if not possible trying keying it out using Larson (2000).
