While better known than the Angolan Talapoin,[2] and recognized as distinct as far back as 1969,[4] the Gabon Talapoin remained un-named until 1997. Kingdon pointed out that the presently used binomial, where the specific name is a reference to the Ogoue, is a nomen nudum:
A nomen nudum, 'Miopithecus ogouensis' is used here [in Kingdon's book] in anticipation of a formal description.[2]
However, it can be argued than his description is valid per ICZN rules,[5] as he provided an illustration (possibly a valid type), a description, and specifically said the name was intended for this new species.[2]
