Your classifications are kind of uneven: according to the NCBI taxonomy "insects" is a superclass, "viruses" is a superkingdom. Why do you have the "other eukaryote" class?

If you have found a specific level (e.g. class or superclass) you could parse the NCBI Taxonomy download files (FTP): first, match your species, second, go up in the tree until you hit your level.

Nonetheless, it's hard to pick a level that feels right. E.g. the superclass of humans would be gnathostomata (class: mammals). Drosophila seems to have no class...

You can use NCBI's taxonomy common tree to get the tax tree,

and you can write a script to reformat it.

You can use the EBI's Ontology Lookup service to query the NEWT Taxonomy Ontology (which is the same NCBI taxonomy but "ontologized" by people at UniProt):

http://www.ebi.ac.uk/ontology-lookup/

The lookup service provides webservices with methods like:

public Map getTermParents(String termId, String ontologyName);
public Map getTermChildren(String termId, String ontologyName, int distance, int[] relationTypes);

which you can use with whatever taxonomy category and specie you want to check whether a particular specie is a child (is included) of that taxonomy category (regardless if that is a class, kingdom, superclass, etc, you would just need to iterate/change distances). Probably you want to go from the specie tax id and up until the root (using getTermParents) and see if you pass by the category for which you want to count.

Good luck!
