I'm guessing it's a Hainan Blue.  However, it's not really clear to me whether female Hainan Blue and Blue-throated Flycatchers could safely differentiated.  I suspect they could be impossible to ID in the field.  It seems the back and nape is grayer on the female Blue-throated than the Hainan Blue but I suppose there could be some variability with that mark.
