So I suppose we can safely say that this species is no longer considered extinct?

Well that is not certain. Because it is known that very low numbers of the host species can result in the extinction of the parasitic species. They cannot infect others good enough. At present, only one male has been discovered, so it is not possible to say that he has the mite.

At present, only one male has been discovered, so it is not possible to say that he has the mite. Exactly, we must remember that some species can succesfully survive in small groups with a very low genetical diversity (Wisents and Cheetah's are good examples) while other species are not so resistant. Maybe the mite was just such a case. Another option is that the largest population of the mite was present in that part of the woodpecker population that has died out. The surviving Woodpecker population might have been relatively free of the parasites and the mite population was too small to survive and eventually went extinct of interbreeding. Anyways: we won't be sure unless we find a living specimen of this species. |

BTW: mites are arachnids and not insects.

Pterotrogus principalis should be the full name. source: S. V. Mironov; J. Dabert; R.
