Nice new paper in Biology Letters about using molecular data to validate the species-level taxonomy of a hummingbird species known from a 100-year old specimen. For more click here.
While not quite the same, there has been an interesting flourishing of descriptions of new species of frogs that appear to have gone extinct many years ago. For a recent example, see here for a paper on Sri Lankan shrub frogs by Madhava Meegaskumbura. Similar papers will also soon be coming out for other genera of frogs. It’s a true shame that we are now describing species that have recently gone extinct because of habitat destruction or the spread of infectious diseases.
