The topology of the tree shows that the genus Dactylopius is monophyletic (they share a common ancestor) and that node 16 divides each tree into two branches which separate the genus biogeographically
Scytalopus parvirostris (apparently disjunct from Amazonas, Peru south to central Bolivia) is known unequivocally from the Cordillera Vilcabamba (across the Rio Apurimac from the main chain of the Andes, biogeographically
closer to Cuzco) in extreme eastern Junin; it may also occur more widely as it is also known from the main chain of the Andes in nearby Ayacucho and Pasco.
The most important issue to highlight is that, although the island lies outside the tropics, biogeographically
the shores may be considered tropical since the majority of their species are known from the Indo-West Pacific Region.
, both the mainland source and island target SDTF areas are large.

Australia was biogeographically

The Maghreb region is highly biogeographically

It has not been previously recorded on any Caribbean island (excluding Trinidad, which is biogeographically

If these relationships are correct, biogeographically
they would also agree with the sister relationships found between other endemic species of the Costa Rican Pacific minforest in the Caribbean minforest zone.
