Exactly! It belongs just to this tribe: Stizocera wagneri (Gounelle, 1913). There are no other pictures of this species in the Web, but it is similar to S. phtisica (Gounelle, 1909).
There is a fairly old key in Portuguese done by Martins & Napp (1983, Papéis Avulsos de Zoologia 35/7: 79-92), which includes all species described until that time and a still valid genus Nostizocera. Nonetheless, it is not an easy key, since it is mainly based on the sculpture of the prothorax and other characters scarcely guessable from photo.
