Dingotangs were chimera-type GELFs: orangutans with the heads of dingoes.
The Dingotangs, along with the other residents of their asteroid belt, were brought there from Earth aboard the Mayflower. The GELFs mutinied and the ship drifted through the omnizone.
Members of the Great GELF State, the Dingotangs were brutal and crude, employed as guards at the prison camp Cyberia on Lotomi 5.
One of the Dinotangs, Deki, had a Symbi-morph consort that he forced to pleasure Lister. (Last Human)
