We identify a high frequency of Type 1 XUV disks, reflecting recent outer-disk star formation, in a sample of 31 E/S0s with stellar masses primarily below M∗ ~ 4 × 1010 M⊙. Our ~40% identification rate is roughly twice the 20% fraction reported for late-type galaxies. Intriguingly, in the dwarf mass regime (below M∗ ~ 5 × 109 M⊙) where gas fractions increase, Type 1 XUV disks occur in ~70% of red-sequence E/S0s but only ~20% of blue-sequence E/S0s, a population recently linked to active disk rebuilding, especially in the dwarf regime. Our statistics are preliminary, but could indicate that Type 1 XUV disks in dwarf E/S0s are primarily related to weak/inefficient outer-disk star formation rather than to star formation capable of driving substantial disk growth.
