Possibly Pagastia due to submental and head setation. Below you find old comments.
Naming history:
- Orthocladiinae indet4
- Diamesinae indet3
- Pagastia indet
Characters
- mentum: 2 small median teeth, 6/7? lateral, submental setation very far away caudad below 6/(7?)th lateral tooth, large ventromental plates;
- postoccipital margin: dark brown

Hi,
first I placed it to Nanocladius, but within Chaetocladius or maybe Parakiefferiella there are similar specimens, but the submental setation isn't the same. The I found a similar submental setation in Pagastia (Diamesinae) but I have no further descriptions or photos available. The “2nd?-stage” head belongs I suppose to the same taxa group, because: a) is in same sample b) same submental setation. Any further suggestions?

It can be confirm that it is not Nanocladius. Setation submenti is a key character of Pagastia, i agree with your opinion. It may be Pagastia orthogonia/lanceolata, both of them are distributed in Palaearctic mountain area, you'd better check some papers of Makarchenko or Endo.
