Large Tongatapu White-eye (Zosteropidae gen. & sp.)

This enigmatic species is mentioned in a list which is included in S. T. Turvey’s ‘Holocene Extinctions’ from 2009, it is supposed to come from the island of Tongatapu, Tongan Islands.

I could not yet find out any more about it, but the author might as well just have mixed up the islands here and probably did actually mean the large white-eye form that is known from subfossil remains found on the island of ‘Eua, the neigbor island of Tongatapu.
