Not all species reproduce sexually. Not all sexual reproduction involves pairs.
I would say none. Maybe to be a member of a species requires at least a history of a single breeding pair?

Tertiary question: we know that Vulcans/Romulans were descendents of the Progenitors, but are Talaxians?
If not, it might not be technically possible for them to interbreed at all, meaning that a Vulcan/Talaxian hybrid could never occur naturally, and also that Tuvix would probably be genetically incompatible with everything and everyone. Therefore, no species - only an anomaly produced by a freak transporter accident.

“A single Tuvix is a curiosity. A wonder, even. But thousands of Tuvixes – isn’t that becoming a race?”
