Some Tropes can be broad. Some can be so broad that even a specific form of them can be Tropes by themselves.
Let's say there's a trope for "Juggling". You realize that "Scarf Juggling" and "Knife Juggling" are common too, to the point where you can think of half a dozen examples for both. Those would be Sub-Tropes, whereas "Juggling" is generally their Super-Trope. In logic terms
, "Juggling" is the genus and the different kinds of juggling are the differentia; they share the same common theme in their definition, but they each have additional features that distinguish one from another.
What makes a sub-trope can vary. Perhaps the most common way is that several examples of a trope have a distinctive common element unseen in the other examples. This distinctive element makes the sub-trope the same, but more distinctive than the broader trope. A trope can have several possible variations built in, and once examples of any of those variations are common/distinctive enough, they form a sub-trope. Any sub-tropes should be listed instead of the super-trope, because the sub-trope implies the super-trope's presence.
Heck, some tropes can be sub-tropes of more than one super-trope. This can be a shared aspect of them or actually combining the two tropes.
The definition of the super- and sub-tropes are what's important. Every example of a sub-trope will also be an example of its super-trope.
Compare Sister Trope.
Compare/Contrast The Same, but More Specific (when a distinction is not enough to make a separate trope).
