Based on my understanding this would not be correct usage.  The 
designation in the case you note should be Staphylococcus n. sp.
meaning Staph new species. 

It is possible that for multiple undescribed species you might 
use Staphylococcus n. spp.; however, this situation is usually
handled with Staph n. sp A, Staph n. sp. B, etc.
