Mitochondrial DNA sequences from populations of these 5 species from throughout their distribution (Maui, Lanai and Molokai) were used to infer the geographic history of the species on East Maui and to determine whether diversification likely occurred in situ, or alternatively whether diversification occurred in allopatry on different volcanoes.
We discuss the possibility that such variation could provide the raw material for habitat selection leading to allopatry.
They are hypothesized to have speciated in allopatry during the Pliocene or earlier (Trewick and Morgan-Richards 2005), and they now have broadly parapatric distributions (Trewick and Morgan-Richards 1995, Bulgarella et al.
First, it is possible that the initial evolution of traits driving reproductive isolation may have occurred under allopatric conditions (Pettengill & Moeller, 2012); a new species that evolved under allopatry may subsequently come into contact along an edaphic boundary and appear identical to parapatric species in being relatively young, ecologically divergent, and reproductively isolated.
