Discussion
Documented hosts from the flora area are Dalea formosa Torrey, D. frutescens A. Gray, Psorothamnus emoryi Rydberg, and P. polydenius (Torrey) Rydberg (Fabaceae). Other species in these genera apparently serve as hosts in Mexico. The taxonomic limits of Pilostyles thurberi are poorly understood. It is difficult to circumscribe the host range of this taxon.
