Discussion

Of conservation concern.

Harmonia guggolziorum occurs in the southern Inner North Coast Ranges. Molecular phylogenetic analyses have indicated a sister-group relationship between H. guggolziorum and the other serpentine-endemic species of Harmonia (H. doris-nilesiae, H. hallii, and H. stebbinsii; B. G. Baldwin 2001).
