We present a simple method for identifying candidate white dwarf systems withdusty exoplanetary debris based on a single temperature blackbody model fit tothe infrared excess. We apply this technique to a sample of Southern Hemispherewhite dwarfs from the recently completed Edinburgh-Cape Blue Object Survey andidentify four new promising dusty debris disk candidates. We demonstrate theefficacy of our selection method by recovering three of the four$\textit{Spitzer}$ confirmed dusty debris disk systems in our sample. Furtherinvestigation using archival high resolution imaging shows $\textit{Spitzer}$data of the un-recovered fourth object is likely contaminated by aline-of-sight object that either led to a mis-classification as a dusty disk inthe literature or is confounding our method. Finally, in our diagnostic plot weshow that dusty white dwarfs which also host gaseous debris lie along aboundary of our dusty debris disk region, providing clues to the origin andevolution of these especially interesting systems.
