===Generate QuickStatements to add "instance of: placeholder taxon" to items with P28 statements===

===Generate QuickStatements to link interaction hosts to their genera===

Have to avoid assigning labels like "Cryptotermes symbiont", instead use "symbiont of Cryptotermes" to avoid false matches.

List interactions where symbiont is member of Alphaproteobacteria according to Wikidata

Get items with a parent taxon that is mapped to a taxon in Wikidata, relying on the taxonomy that is given there.

We rely on parent taxon being mapped to Wikidata, rather than the taxon itself being mapped to Wikidata, because not all taxon items represented in this Wikibase are suitable for being added to Wikidata, e.g. informally named taxonomic units, even though there is some information on their taxonomic position.

Query works without timeout even with large taxa like Bacteria.
