It all depends what you mean by higher and lower.  I would avoid this usage
if you can.
That said, look to other protists in this order:
1) other ciliates
2) dinoflagellates
3) apicomplexans
4) oomycytes
5) chrysophytes

These are all part of a "late eukaryotic radiation".
The first 3 form the Alveolata
The latter 2 seem to always come out near the first 3 in molecular analyses.
If that doesn't help, try Saccharomyces.
