Abstract: 

The complex geological history of the Indonesian island Sulawesi has
shaped the origin and subsequent diversification of its taxa. For the
endemic freshwater snail Tylomelania a vicariant origin from
the Australian margin has been hypothesized. Divergence time estimates
from a mtDNA phylogeny based on a comprehensive island-wide sampling of Tylomelania
fit regional tectonic constraints and support the ‘out-of-Australia’
vicariance hypothesis. The Banggai-Sula region of the Sula Spur, the
Australian promontory colliding with West Sulawesi during the Miocene,
is identified as a possible source area for the colonization of Sulawesi
by the ancestor of Tylomelania. The molecular phylogeny also shows a rapid diversification of Tylomelania
into eight major lineages with very little overlap in their
distribution on the island. Haplotype networks provide further evidence
for a strong spatial structure of genetic diversity in Tylomelania.
Distribution boundaries of the major lineages do at best partially
coincide with previously identified contact zones for other endemic
species groups on Sulawesi. This pattern has likely been influenced by
the poor dispersal capabilities and altitudinal distribution limits of
this strict freshwater inhabitant. We suggest that late Miocene and
Pliocene orogeny in large parts of Sulawesi has been the vicariant event
driving primary diversification in Tylomelania.
