"Spomenik" definitely means "monument" or "memorial". In a specific context, it also means "tombstone".

"Spomenica" is much less used. I'm a native speaker -- born and raised in Belgrade -- and I've only heard it in very specialized and rare occasions, so I'm having a hard time translating it correctly. In the context I've heard it used, it's an award or recognition, usually in the form of a scroll or a medal.

I like the authors use of the native word "spomenik" to talk about this specific style, but it's definitely just the author's artistic choice.
