[Taxacom] North America, Central America + S.E. Asia sister taxa

[John Grehan]

I will also be interested to know where the related groups are, and also the details of the range of the two sister taxa.

The Schisandraceae have a distribution between eastern India across china to Japan and south to Sulawesi, and Florida and central eastern Mexico next to the Gulf of Mexico - at least according to one rendition of that family but perhaps that's all changed with subsequent molecular classification.

Ah, so the carabid clade is?*east* of the Rockies - then my suggestion of?trans-Pacific connections for the carabids was probably wrong, and it's?more likely to be?a Tethyan group.??I agree with Ken that the group was probably?present?earlier?in Europe and central Asia, although?there is no?need for these populations to have had any special phylogenetic significance.?

Kip -?where is?the sister group/s of your clade?

Hi Kip,
? ? ? 
 Your beetles sound like they may have a somewhat similar evolutionary origin to a bird sister-group pair, Hemiprocnidae and Apodidae.?  The Hemiprocnidae has a South East Asia range that is broader, but centered around the Vietnam-Myanmar area.? 

? ? ? It's sister group Apodidae apparently arose further west in Eurasia (with at least one stem-genus known from Europe).? Your beetles could have spread west into eastern North America along with Apodidae.
Of course, Apodidae has spread and diversified much further, but your beetles could have had competitors that prevented them from expanding into South America, Africa, etc.? Anyway, I would not be surprised to find European fossils that are stem members of your North and Central American beetle group.

Dear All,
I am looking for examples of taxa with demonstrated sister groups in which one is endemic to all or part of South East Asia and the other to all or part of North and/or Central America. Any citations or clues appreciated.
