Host Plant: Broussaisia arguta . Coll: D.A. Polhemus. Deposited in D.A. Polhemus’s personal collection at the Smithsonian, Washington D.C. Etymology. This species is named after Dr. Patrick O’Grady (Hawaiian Dipterologist) for his invaluable contributions to this project and for his positive scientific mentorship of G.M. Bennett. Discussion. Nesophrosyne ogradyi represents a lighter form than N. broussaisiai . External morphology is nearly identical to N. kaupoi . Nesophrosyne kaupoi is distinguishable from N. ogradyi by its absent apical processes.
