The Pu Hoat muntjac is a species of muntjac known only from the Pu Hoat region of Vietnam, which borders Laos. It is sometimes considered conspecific with Roosevelt's muntjac, and its habitat and behaviour are likely to be similar (Wikipedia, general species account).
It has been recorded only once, at its type locality of Hanh Dich Village, Que Phong District, Nghe An Province.
