I see a problem with the "taxonomically homogeneous" since many taxa are not.
All obligatory mutualistically symbiontic organisms are excluded (you
mention symbiont, but the symbiont is the part of a symbiontic
relation, e.g. both the algae taxon and fungus taxon each are a
symbiont in a lichen.

Contradict if my German biology is at odds with English.

The problem is, that individual and set are mixed, so that the
"homogeneous" appears to apply also to the individual. Proposal:

Definition:     The information class pertaining to a specific
instance or set of instances of a life form or organism (virus,
bacteria, symbiontic life forms, individual, colony, group,
population). Sets must reliably be known to taxonomically homogeneous
(including obligatory symbiontic associations).
