 Found in my house in Oslo, Norway

With the Dutch key (Van Veen) and the Germans key (Geller-Grimm) I arrive at Tolmerus atripes. However, this species is not known from Norway or Northern Europe.

Small black asilid with rather long wings, ca12mm.

What do you think?

 The legs are partly (dark) red. atripes would have entirely black legs. Females are near to impossible to ID. This one looks like atricapillus
