Steigertrude

Steigertrudes were an extra-terrestrial species who looked like warthogs.

The Doctor once had an encounter with Steigertrudes which involved android replicas.

One Steigertrude owned a restaurant on Hyspero which was visited by the Eighth Doctor, Sam Jones, Iris Wildthyme, and Gila. (PROSE: The Scarlet Empress)

According to Icarus, they were "art criminals", a race "pledged to trawl the Enclave in perpetuity burning up artworks of any kind". The group which raided Earth's art treasures was comprised entirely of females, and were led by Emba, who was atypically keeping the art rather than burning it. (PROSE: The Blue Angel)
