One of the most common questions during the last couple of weeks has been "how did you end up with a Darwin specimen?" The short answer is that I was the right person at the right time.
Here is the long answer: Insect systematists are very specialized scientists. I can identify most beetles to families. I can identify rove beetles (the family Staphylinidae) to the subfamily level and I can identify most Staphylininae (one of the subfamilies of rove beetles) to tribes and subtribes. I can name almost all species in my taxonomic expertise (the subtribe Xanthopygina) but ask me about subfamilies of Orthoptera or Diptera and I have no clue.

The Darwin specimen happened to belong to the subtribe Xanthopygina and I guess I was the best person in the world to tell if this was a new species and a new genus.
Back in 2008 my colleague
Alexey Solodovnikov (University of Copenhagen) told me that there was a "Darwin Xanthopygine" in the Natural History Museum of London. To be honest, I think I just said "OK" and did not think much about it. Later, I even visited the BMNH and I failed to locate the specimen myself. The thing is, I was not really looking for it. My main goal during that visit was to photograph the vast type collection of Xanthopygina by
Sharp. So I was really photographing types and paid little attention to unsorted materials.
Alexey later told me that he had found the Darwin specimen in a box of random unsorted Staphylinidae that included both new and historical materials. Realizing that this is a Xanthopygine, he transferred it to the unsorted materials of the genus
Trigonopselaphus, as the best guess on where this specimen might belong
. However, at this point neither Alexey, me or anybody at BMNH knew/realized that this specimen was considered lost according to
Smith (1987)

Trigonopselaphus sp. |
Fast forward a few years and I have decided to revise the genus
Trigonopselaphus (revision is in progress). Typically, one requests all described materials (types) and any unsorted/unidentified materials that belong in that genus. I requested materials from several museums, including BMNH. It was only then that I saw the Darwin specimen and quickly realized that it is a new genus and new species. But it would be another few months before I realized that the specimen was considered lost, while I compiled an inventory of all rove beetle specimens collected by Darwin.
The thing is, it takes a lot of time and preparation to be able to tell if a specimen you see is "new". If I had seen the Darwin specimen in 2004 or 2008, I would have been able to tell that is is a Xanthopygine, but I do not think I would have been able to recognize it as something new.
