I still think the outgroup homogeneity effect covers this idea more directly as a term. Here's from Dave Myers' Social Psychology text: Outgroup homogeneity effect: Perception of outgroup members as more similar to one another than are ingroup members. Thus "they are alike; we are diverse."
Here's the source: Ostrom, T.M., & Sedikides, C. (1992). Outgroup homogeneity effects in natural and minimal groups. Psychological Bulletin, 112, 536-552.
