The small moth appears to be a Kearfott's Rolandylis Moth (Rolandylis maiana).
It took a few trips through the same set of moth plates for me to figure out that this is probably a Decodes basiplagana, a tortricid that appears to lack a common name.
After I posted this on Flickr, Ali Iyoob suggested Palmerworm Moth (Dichomeris ligulella), which seems to fit the shape of this moth pretty well. Sometimes it pays to revisit unsolved identification problems!
