[Taxacom] Taxacom Digest, Vol 185, Issue 22

[Brendon E. Boudinot]

Dear John,

Would you please clarify the hypothesis that you are proposing? If I
understood you correctly, you are hypothesizing that the most recent common
ancestor of the crown group of the genus *Syscia* was distributed across
Gondwana, and that subsequent rifting, *etc.*, led to the
presently observed distribution of the clade? If this is not correct,
please do outline the scenario.

Cheers,
Brendon
