No.

At the moment there are no species in OWL 1.1. Reification is used in  
the RDF mapping to encode axiom annotations (a bit brokenly at the  
moment). Being used as syntax like that would suggest ruling them out  
(i.e., it's that sort of consideration that make domain modeling  
using rdf:List owl full), but one hopes the criteria will evolve a  
bit ;)
