Fredericus Anna Jentink (20 August 1844, Wymbritseradeel – 4 November 1913, Leiden)[1] was a Dutch zoologist.
[1] In 1895 he was president of the 3rd International Congress of Zoology in Leiden[2] and he was among the founding members of the International Commission on Zoological Nomenclature besides Philip Lutley Sclater, Raphaël Blanchard, Julius Victor Carus, and Charles Wardell Stiles.
[3] Jentink's main research field was the taxonomy of mammals, where he described several marsupial, bat, and rodent taxa.
[5] The original provenance of this species is still unknown[4] but alternatively it might be possible that it is a hybrid between the greater spot-nosed monkey and the moustached guenon.
[6] Jentink published the Catalogue ostéologique des mammifères (1887), the Catalogue systématique des mammifères (1892) and Mammals Collected by the Members of the Humboldt Bay and the Merauke River Expeditions:Nova Guinea (1907).
