The '''Colobinae''' or '''leaf-eating monkeys''' are a [[family (biology)|subfamily]] of the [[Old World monkey]] family that includes 61 [[species]] in 11 [[genus|genera]], including the [[black-and-white colobus]], the large-nosed [[proboscis monkey]], and the [[gray langur]]s. Some classifications split the '''colobine''' monkeys into two tribes, while others split them into three groups. Both classifications put the three African genera ''[[Black-and-white colobus|Colobus]]'', ''[[Red colobus|Piliocolobus]]'', and ''[[Olive colobus|Procolobus]]'' in one group; these genera are distinct in that they have stub thumbs (Greek κολοβός ''kolobós'' = "docked"). The various Asian genera are placed into another one or two groups. Analysis of [[Mitochondrial DNA|mtDNA]] confirms the Asian species form two distinct groups, one of langurs and the other of the "odd-nosed" species, but are inconsistent as to the relationships of the gray langurs; some studies suggest that the gray langurs are not closely related to either of these groups,<ref name=Sterner2006/> while others place them firmly within the langur group.<ref name=Osterholz2008>{{cite journal | last1=Osterholz | first1=Martin | last2=Walter | first2=Lutz | last3=Roos | first3=Christian | title=Phylogenetic position of the langur genera Semnopithecus and Trachypithecus among Asian colobines, and genus affiliations of their species groups | journal=BMC Evolutionary Biology | publisher=Springer Nature | volume=8 | issue=1 | year=2008 | issn=1471-2148 | doi=10.1186/1471-2148-8-58 | page=58|pmid=18298809|pmc=2268674 | doi-access=free | bibcode=2008BMCEE...8...58O }}</ref>
