S. warneri vs. S. xylosus

Hello everyone,

Can anyone suggest a test (or 2 or 3) which would differentiate 
Staphylococcus warneri from Staphylococcus xylosus? I would think xylose 
is one, but here is why I ask:

A senior colleague of mine went to see the Riboprinter this week. He took 
three organisms which I had identified with Vitek. Two were 
Staphylococcus haemolyticus, and they checked out on the Riboprinter too. 
The third one, however, had ID'ed on Vitek as 97% S. warneri/3% S. 
xylosus. According to the Riboprinter, it was S. xylosus. I'm curious 
(and so is my colleague) to try some additional supplemental testing, 
although I may run a repeat Vitek on it as well.

Thank you kindly for your help.
