I don't see the discal bristles on tergite 3 and 4, also with Tschornig I would not key there as I see more than 1 bristle at the base of r4+5 and I am not sure if it has 4 st. Also more early in the key of Tschornig I have problems interpreting if the prealar seta is larger or smaller than the posterior notopleural seta, just posterior to the notopleuron there is one large seta and just in front a small seta, I am not sure if the small one also counts as a prealar, or if only the big seta is the prealar seta. Unfortunately I don't manage to take good pictures of it with my cell phone.

Here are some additional pictures of the specimen including a ventral view of the abdomen.
