L. pittfieldae is the only member of its genus found anywhere in the fossil record, though their are five living species. All of those species are uncommon in the West Indies, which may point to why only one example of L. pittfieldae has ever been found; it was uncommon in that area as well.
I chose this animal today because it just goes to show that there are things out there that we may have never known about. This particular wasp was only discovered two years ago and is known only from one tiny specimen. How many other fascinating creatures of the past are still undiscovered?
