Olona Picturewing Fly (Drosophila toxochaeta)

The Olona Picturewing Fly was described in 1990.

The species is known from three (?) specimens that were collected in 1972 and 1973 in the wet forest on the island of Moloka’i, Hawaiian Islands; two two of them had been reared from the stems of the Hawaiian endemic nettle shrub Olona (Touchardia latifolia Gaudich.). [1]

The Olona Picturewing Fly was not seen alive since the 1970s and is thus considered most likely extinct.
