Male. Unknown. Hosts. Reared from galls induced by an unidentified Cecidomyiidae on Ocotea tenera ( Lauraceae ). The galls are induced in male flowers on male trees and resemble the fruits produced on female trees.

Distribution. Costa Rica.

Material examined.

Holotype ♀ COSTA RICA, Puntarenas, Monteverde vicinity, 1200–1500m, iii.1997, from Ocotea male flower, N. Wheelsprite ( NHMUK).

Etymology. Named after the host plant from which this species was reared.
