Posterior setas on f2 and f3 absent - not arrogans, montana, punctifrons, robusta.
Frons not completely shining - not hyalipennis.
Anterior margin of frons shining - not elata, ferruginea, fuscinervis.
Either frey or silvatica.
But on your image is clearly visible that brown part of occipital spot is subtriangular which divides T. sylvatica from T. frey.
So, Tetanocera sylvatica.
