What subtle physical difference distinguishes female Panamanian white-faced capuchins?
They may exhibit brownish or grayish elongated frontal tufts that contrast with their pure white cheeks and throat.
Despite the close physical resemblance between the Colombian white-throated capuchin (*C. capucinus*) and the Panamanian white-faced capuchin (*C. imitator*), subtle morphological distinctions exist, particularly in females of the Panamanian variant. A specific feature reported for these females is the potential presence of elongated tufts of hair on the forehead area. These tufts are described as being brownish or grayish in color. This coloration is noteworthy because it stands out in contrast against the adjacent areas of their face, specifically their pure white cheeks and throat, serving as a potential subtle physical marker for identification when distinguishing them from the closely related Colombian species.
