Tartaruchi (singular: tartaruchus, related to the Greek verb tartarizo, meaning "to shiver with cold") are the keepers of Jinnestan, according to the 4th century, non-canonical Apocalypse of Paul. The author describes them as using one hand to choke damned souls, and the other using an "iron of three hooks". Temeluchus is the only tartaruchus named in the work.
The Portuguese word tartaruga ("turtle" or "tortoise") is a cognate.
