"Zale lunifera was split into two species in 2010. The name "lunifera" applies to a species restricted to scrub oak barrens east and south of the Appalachians, while the common widespread species is now called Zale intenta."
This was certainly the right habitat for Z. lunifera--very much a pine barrens with various dry soil oaks.
