It does seem distinctive. But this is still the first evening spent with the new…

batch of DNA. I think I should give it another look tomorrow. The species is quite striking. Isn’t it?

I’ve kidded David (every once in a while) about the preponderance of rhacopus that is produced in Luzerne County. It seems there are other Vaginatae as well. And this one is extraordinary.

Very best,

Do you have enough data to generate a cryptonomen temporarium for this species at this time?

We have DNA from this material now. It is a new species.

It has the TCT… initial string on the nrLSU gene (hence, it is in the provisional series “Penetratrices”). I’ve just got the nrLSU sequence so far. It is genetically distant from just about everything in the Vaginatae (where it appears to belong). Of course, with the unusual “left hand end” of nrLSU, its best matches are to a few species of the Penetratrices group such as sp-AUS09, sp-AUS11, and insinuans.

More sometime soon.

Thanks for this cool material.

Very best,


Thanks Dave,
