Morphological and behavioral data suggests that Myiozetetes is most closely related to the genus Legatus (del Hoyo et al. 2004). Myiozetetes has shares nesting behavior similarities with Pitangus (del Hoyo et al. 2004). The Social Flycatcher has seven recognized subspecies; however, M. s. primulus, hersperis and texensis may in fact form a separate species (del Hoyo et al. 2004).
