Discussion. Stenorhamphus mixtus was described as a fossil in the genus Collarhamphus due to apparently sharing similarities with all three extant Collartidini genera. As the three genera of Collartidini share many similarities, distinguishing between them can be extremely difficult. However, our morphological analyses placed Collarhamphus within the Mangabea + Stenorhamphus clade. Though not within Emesinae , previously described coleopteran Baltic amber fossils have been placed within extant genera ( Alekseev, 2013). We feel confident in synonymising Collarhamphus with Stenorhamphus . This further emphasises the age of this group to be between 36 to 54 million years old ( Wolfe et al., 2009) and that little morphological change appears to have occurred during this period.
