As the type for subgenus Californicallis, M. agrifolicola can be distinguished from other Myzocallis species by characters diagnostic of this subgenus. Specific morphological features distinguishing it from congeneric species require examination of the original species description (Richards 1966) and the subgeneric key provided in Quednau and Remaudière (1994).

Habitat

Associated with oak (Quercus) in California.

Distribution

California, western North America. The specific epithet and subgenus name suggest a geographic restriction to California.

Some sources (e.g., Catalogue of Life) list this species as a synonym, though GBIF and other taxonomic databases currently recognize it as accepted.

Subgeneric placement

The subgenus Californicallis is one of ten subgenera recognized in Myzocallis, distinguished from nominotypical Myzocallis and other subgenera by morphological characters detailed in the 1994 revision.
