Hi,

I'm having some difficulties deciding on the species of this specimen, and I don't have any identified material with which to compare.
Outer vertical bristles seem to be relatively large, and mid tibiae seem to have 3 ad. But the calyptrae are white with yellowish edge, but perhaps this is a less important feature. As for the genitalia, I can't make up my mind with only illustrations to compare.
All things considered, I think it's probably T. solivaga, but would like confirmation if possible.

The number of bristles is difficult and sexual dimorph.
Me personally rely more on the length of outer vertical bristle, which is pretty strong in your case, hence solivaga indeed.
