I am not a primatologist (actually, I'm a marine biologist; a bit
of a stretch, no?), but I recall reading in a couple of animal
behavior seminars from my grad student days that most primates
that exist in structured social groups have sex-specific dispersal
patterns, that is, that males disperse from such groups whereas
females do not. The group "lineage", then, is not isolated from
gene flow from other groups as males imm/em-igrate from/to groups.
Speciation would be impossible in the face of continued gene flow.
Somebody more knowledgeable than I please insert some information
about patterns of dispersal among current social primates.....
