Dear Elena,
here I'm attaching you photos of female T. fragilicornis (ZFMK, Bonn Museum). Regarding your photos, definitely it is not Savtshenkia because of elongated hypovalvae. The female from your pictures has typical reduced hypovalvae of virgatula species group (Vestiplex), so it is T. fragilicornis.
Cheers, P.
