Anthonomus defossus? Snout Beetle Fossil

These images show snout beetle or weevil insect fossils of the Order Coleoptera, Family Curculionidae found in the Florissant Formation of Teller County, Colorado, USA. I wonder if this insect was in the Anthonomini weevil tribe in the subfamily Curculioninae and maybe genus Anthonomus (Gemar, 1817) or species Anthonomus defossus (Scudder, 1876).  It dates to the Chadronian Stage (37.2 - 33.9 million years ago) Eocene Epoch of the Paleogene Period. Thanks to Doug for the image. Fossils were uncovered in September 2021. Field of view is 2 mm.
