It is endemic to the state of Rondônia, and its range bordered by the Rio Mamoré, Rio Madeira, Rio Ji-Paraná, Serra dos Pacaás Novos[2] and possibly Bolivia. It was only described in 2010, and its name refers to the famous Amazonian explorer Cândido Rondon.[2] Prior to its description, it was included in Emilia's marmoset (Mico emiliae).[2] Rondon's marmoset is a member of the silvery marmoset (Mico argentatus) group within the genus Mico. Like others in its group, its pelage is generally silvery-gray. It has dark fur on much of its head, forehead and the sides of its face, which contrasts with a whitish patch in the middle of its forehead. The fur on its legs become reddish-brown on its shins and almost black at the ankles. Its tail is mostly black. It averages about {{convert|330|g|oz}} in weight. Length excluding tail averages about {{convert|22|cm|in}} and the tail averages about {{convert|31|cm|in}}.[2] Exudates are an important part of Rondon's marmoset's diet, and like other marmosets its digestive tract is specially adapted for this purpose.[2] Adaptations include chisel-like lower incisors, which can gouge gum-producing trees to begin a flow of exudate, and an enlarged cecum, which helps digest the exudates.[2]Despite being able to tolerate habitat disturbance, Rondon's marmoset may be the most threatened species in the genus Mico.[2] It is considered vulnerable by the IUCN,[1] though it has been suggested that data deficient would be more appropriate.[2] Another callitrichid, Weddell’s saddleback tamarin (Saguinus fuscicollis weddelli) also occurs over much of Rondon's marmoset's range.[2] However, Rondon's marmoset is rare or absent from areas where Weddell's saddleback tamarin is common.[2] Weddell's saddleback tamarin is known to take over Rondon's marmoset's gum feeding sites.[2] References1. ^1 2 {{Cite journal | author = de Oliveira, M.M. | author2 = Rylands, A.B. | author3 = Ferrari, S.F. | author4 = Silva Jr., J.S. | last-author-amp = yes | title = Mico rondoni | journal = The IUCN Red List of Threatened Species | volume = 2008 | page = e.T136804A4341743 | publisher = IUCN | date = 2008 | url = http://www.iucnredlist.org/details/136804/0 | doi = 10.2305/IUCN.UK.2008.RLTS.T136804A4341743.en | access-date = 25 December 2017}} {{Callitrichidae nav}}{{Taxonbar|from=Q1187101}}{{DEFAULTSORT:marmoset, Rondon's}}2. ^1 2 3 4 5 6 7 8 9 10 {{cite journal|title=Rondon’s Marmoset, Mico rondoni sp. n., from Southwestern Brazilian Amazonia|author1=Ferrari, S.F. |author2=Sena, L. |author3=Schneider, M.P. |author4=Silva Jr., J.S. |lastauthoramp=yes |journal=International Journal of Primatology|doi=10.1007/s10764-010-9422-6|year=2010|url=http://www.springerlink.com/content/q1784x5700x53524/fulltext.html}} 4 : Mico|Endemic fauna of Brazil|Mammals of Brazil|Mammals described in 2010 |
