Having checked some keys I definitely think it is T. ferruginea.

The apical setae are rather variable and many ferruginea (checked from genitalis) have only one strong preapical. The frontal stripe is very different in fuscinervis. One good (but not 100% reliable) character is the number of ad setae on hind femur: 3-4 in ferruginea, 2 in fuscinervis.

The frons shining/not shining is very easy to use use you have seen the various forms.
