Hi. I suppose image on the right does not picture M. rondoni, what one can tell looking on the pictures in The Handbook of the Mammals of the Wold, volume 3, p. 306 (tabl. 19) or in All the Mammals of the World. I think it could be mistake, as a monkey n the picure looks more like M. melanurus. Mpn (talk) 13:30, 26 December 2023 (UTC)[reply]
But here is a completely different drawing of this monkey, the same author. Similar (author of Toni Llobet) in All the Mammals of the World from 2023. Arturo24 (talk) 19:15, 26 December 2023 (UTC)[reply]
