Use of parentheses

Presumably the origin of the problem is precisely that it could be
interpreted that "a species-group name is combined with a generic name" Bus
when this species is described as Aus (Bus) xus...?
(I.e., a confusion between "generic name" and "genus-group name".)
Article 5.1 states "The scientific name of a species [...] is a combination
of two names (a binomen), the first being the generic name and the second
being the specific name.", and article 6.1 : "The scientific name of a
subgenus, when used with a binomen or trinomen, must be interpolated in
parentheses between the generic name and the specific name; it is not
counted as one of the words in the binomen or trinomen."
Here, the original name of the species is the binomen Aus xus Smith, 1900;
that Smith placed it in a particular subgenus Bus doesn't change anything
to this.

Note that, with old publications, it can sometimes be difficult to decide
whether a species was actually described as Aus (Bus) xus or as Bus xus,
which can also be the source of inconsistencies in the use of parentheses.
