One female from Geospiza fuliginosa from Narboro, and one male 

 from Geospiza species from Hood. It is surprising to find this else- 

 where extremely widespread and abundant Docophorus of passerine 

 birds so rare in the Galapagos Islands. The only host genus noted 

 is one peculiar to the islands.
