Just trying to make sense of that cladogram. The Barbata group in particular seem to be all over the place. For example, I've always considered the following groups to be closely related species.
callosum / barbatum / lawrenceanum
wardii / venustum / sukhakulii
papuanum / bougainvilleanum
Yet from my interpretation of the cladogram they are not that closely related at all. Callosum is more closely related to wardii and purpuratum then it is to either barbatum or lawrenceanum. Papuanum is more closely related to barbatum and superbiens than it is to bougainvilleanum. Venustum and sukhakulii are closely related but not to wardii.
