An interesting paper published in the latest issue of Bulletin BOC, the authors summarize the confusing history of this bird. They also mention that mtDNA by Naturalis revealed that it represents a melanistic specimen of G. philippensis.
It is a shame though that the results by Naturalis remains unpublished.
