Berosus rugulosus?
So, using Ms. Van Tassell's 1963 key, the elytral apices are without spines; the last abdominal sternite has two small teeth, and the mesosternal protuberance is hoodlike and excavated. Would B. rugulosus be accurate? I was guided by Margarethe's dialog with you at: https://bugguide.net/node/view/383636/bgpage And, Jesse Ray's excellent elytral spine detail (mine has none) at: https://bugguide.net/node/view/686358/bgpage
