In 1976 one of the authors saw a pet turtle which he recognised to be Phrynops hogei. This was remarkable because hitherto the type specimen, first described in 1967, was the only one known to scientists. However, since 1976 three other live animals have been seen, and also eight museum specimens. From the new information the authors conclude that the range of the species is small, and also that the type locality was wrongly given. They think the turtle may well be endangered, and suggest a captive breeding programme for its conservation.
