I would say yes.
Just the Name, Please
Please don’t add information to a name in addition to the name itself, e.g. “grumblefoots (this genus is monotypic, just ID to species!).” We use names in a lot of places for a lot of different reasons and adding extraneous information just makes them more confusing to users and more cumbersome to incorporate into designs (e.g. they might make it impossible to show a common name and a scientific name at the same time). If there is a real problem with misuse of a name, we would prefer to handle it in code and not in the name itself.
If a species has no common name in usage, please don’t make one up.
