is a species of the Waikamoi forest area (Fig. 101), with historically collected specimens from Olinda and Kula Pipeline (~1200 m elevation) complemented by more recent collections in the Honomanu drainage at ~1700 m elevation. Associated ecological collection data are limited to beating ferns, and sifting moss and leaf litter.
