J. Longino, Jan 2020: Casadei-Ferreira et al., 2020 resurrect P. obscurior, which had been synonymized under P. susannae. They say that the two species differ in pronotal pilosity of the major, but that sites of sympatry are unknown. Pheidole susannae is a widespread, somewhat weedy species, with variable pronotal pilosity in majors. I have not been able to see the difference they describe.
