That is certainly a difference.  The real question is, is it
a genus level difference, or only a species level difference.
That sort of decision is at least partly a judgement call,
and there is bound to be some difference of opinion on this.

The difference in armor shape seems, to me, to be slightly more
substantial than can reasonably be included in one genus.
