It doesn't have to accompany it. Each species has a unique name and may be
referred to alone. Each taxon (clade or species) may be prefaced by one or more
taxa which include them, either by hypothesis (subjective) or by definition
(objective), but these lists do not constitute single names. Examples:

_mongoliensis_ (2) Osborn 1924 (1 full species name)

_rex_ Osborn 1905 (1 full species name)

_rex_ (1 abbreviated species name; can be used after full version is cited if
there are no species with homonymous abbrevations)

_Tyrannosaurus_ _rex_ Osborn 1905 (1 full clade name, 1 full species name)

_Saurornithoides_ _mongoliensis_ (1 full clade name, 1 abbreviated species

_T._ _rex_ (1 abbreviated clade name, 1 abbreviated species name)

_Troodontidae_ _Saurornithides_ _mongoliensis_ (2 full clade names, 1
abbreviated species name)

_Dinosauria_ _Ornithischia_ (2 full clade names)

But these are unstable, unless you decide upon some objective means of which
genus name to make part of each species name. And in that case, the genus-based
praenomen will not have anything to do with the species' actual relationships;
names like _Megalosaurus wetherilli_ will be possible.

That "commentary" (the citation) is part of the full name.

But species are not always guaranteed to stay in "their" genera (this case
aside). Non-type species move about all the time, which is good because it can
reflect the latest thinking, but is bad for trying to achieve stability with
"genus + species" combinations.

As evidenced by the widespread usage of "T-Rex", I don't think "normal" people
care too much about such fineries of nomenclature. Whether _Triceratops_ is
made a clade or a genus or a species, kids will still call them "three-horns".
